Then we moved to some heavier-duty 7-gauge flat stock, again testing how each bit made it through the test. We did our best to maintain similar speeds and pressure throughout each portion of every test. Afterward, we did our best to hand sharpen each of the larger bits with a file. The bits that passed these tests were given awards based on their strengths.

While we don’t have an immediate use for a dozen ¼-inch drill bits, we do like that a full-time shop can order enough bits from Drill Hulk to replace their most commonly used sizes without purchasing a whole kit that contains unneeded sizes. However, we did notice that these bits can walk slightly, despite the 135-degree split point.

Manufacturers measure drill size by the “throat distance,” or the distance between the drill bit and the stand that supports the motor. Manufacturers like to double that distance to size their drill presses. For example, a drill press with a length of 6 inches from bit to stand would be a 12-inch drill press.

Drill presses are most useful for drilling precision holes in materials like wood, metal, and plastic. These holes could be for furniture joinery, bracketry, and other custom projects.

For those building their workshops around furniture and cabinet making, there’s no replacement for a good benchtop mortiser. While this isn’t exactly a drill press, DIYers can remove the mortising chisel and use it for some of the same functions (albeit with a longer bit). This makes it versatile enough to offer a drill solution in a pinch, with the ability to cut perfect mortises in sturdy stock. The 3/4-horsepower motor has plenty of power for hardwoods like walnut and locust but only runs at one speed (1,725 rpm). During the test, the first thing I noticed was the Powermatic’s advanced hold-down system, as it can slide back and forth to clamp a workpiece in place. Also, it had lots of power, not letting the bit bog down at all while drilling through wet wood. The accurate depth stop is a plus, and the fact that it can handle different mortising chisels sizes is as well. My only complaint is that it’s not exactly a drill press, so it will require longer bits, but it’s more than capable of most drilling needs.

Through hands-on testing, we found a number of drill bit sets that rise above the competition and help make holes in myriad metals. Some of the results were truly surprising. For those of you working on a project that requires drilling through metal, read on to learn about the factors to consider before shopping for the best drill bits for metal.

While drill presses are kind of an old-school tool, they have gotten some recent updates to make them a little safer. Features like bit guards help to keep hands away from a spinning drill bit and prevent scraps of metal and wood from flying toward the user’s face. Oversize on/off buttons help users quickly shut a machine off if something does go wrong.

During the test, I found the Jet to be incredibly smooth and quiet compared to the other models. I also liked that it offers many pulley combinations for adjusting speed (which was a little confusing at first). Also, the heavy-duty motor didn’t appear to bog down at all, regardless of what I threw at it. The only real concerns with this model are that it’s expensive and very heavy (over 150 pounds).

Other helpful accessories include clamps and jigs that can bolt to the drill press’s table to hold workpieces at specific angles for safe and accurate drilling.

To be 100 percent upfront, we have never liked DeWalt drill bits. We have found that they’re usually relatively low quality and pretty much “throwaways.” But this particular kit was incredible when it came to drilling metal. They didn’t walk at all, and they cut long, continuous, spiraled shavings—the sign of a sharp bit. The rounded shanks on the smaller bits did spin a little, but the no-spin shanks on the larger bits were great. Each bit stayed cool with a spritz of lubricant and remained sharp throughout the test. And, surprisingly, this budget kit drills through wood faster than some of the much more expensive drill bits in the test.

When it comes to enlarging hotels in metal materials, a step bit like the ones in this five-piece kit from Comoware is the tool for the job. This kit features five different sets of bits, each with a series of steps, totaling 50 sizes from one kit. Sizes range from ⅛-inch to 1 ⅜-inch wide.

Bits that drill through metal are further classified by the types of metal they puncture. For example, some bits are capable of drilling through ferrous metals, such as cast iron, and others through nonferrous metals, such as copper and tin.

Look for the words “metal drilling bit” on the package, followed by a list of metals the bit is designed to puncture. Here are a few additional tips that will help drill smoother holes and keep bits in tip-top shape.

Some shank designs are more conducive to drilling through metal than others. Most shanks for this type of drill bit are either no spin or hex.

The table tilts either side up to 90 degrees, making drilling endgrain on woodworking projects a snap. It includes the drum kit with 1-, 1½-, and 2-inch drums and sandpaper. When used in sanding mode, the drum oscillates up and down. The unconventional round worktable features a circular cutout for the sanding drum—perfect for fine, detailed sanding jobs.

There’s only one good way to test drill bits for metal: We needed to put some holes in some metal! We grabbed some scraps of metal off our welding cart, chucked some bits into our drill, and started drilling.

The bits didn’t cut quite as fast as some of the other drill bits in the test, but they did retain their edge nicely. They also didn’t walk at all when starting the bit, and the tap size chart inside the kit could definitely come in handy. What we didn’t like was the fact that every bit, despite its size, features a rounded shank. But the sturdy case with a spring-loaded latch ensures this kit stays shut, and the rubber molding on the case can prevent it from slipping off of a work surface.

Look for a model with a laser guide to really take a drill press game to the next level. These guides are often crosshair-shaped lines that align with exactly where the drill bit point touches the workpiece. Once adjusted, it will be easier to pinpoint every drop of the drill press.

I took this into consideration as I was putting together a list of the best benchtop drill presses. Doing so was a lot of work, as I wanted to suggest only top-quality models with features that matter. So, I pulled several models from brands that had those features, and then I pitted them against each other.

Even the most seasoned drill press operators can use a bit of guidance now and then. Choosing a drill press with an onboard light will help them see better if the drill press is in the darker corners of a workshop, ensuring more accurate drilling.

These are great bits, but we found they were better for enlarging holes than actually drilling them (at least when it comes to metal). If we started with another bit to drill the initial hole, we could quickly work up to the desired size with the Comoware (the tips of the bits themselves just didn’t seem sharp enough for metal). We liked that there are so many sizes in one kit, and the spring-loaded center punch worked well for locating the bit.

For hobbyists and folks who work on literally small projects, Dremel’s drill press rotary tool workstation can turn their standard rotary tool into a mini drill press. This workstation offers 2 inches of travel and features a telescoping pole for attaching the onboard bit and tool holder and other attachments. The rotary tool simply attaches to the workstation with a plastic nut.

This kit comes with 14 bits from 1/16 inch to ½ inch, all of which are made of high-speed steel. The smaller bits have rounded shanks while the larger bits have no-spin shanks. Each bit features the brand’s “black and gold” coating designed to keep them from rusting. Everything stores away in a see-through case, helping to keep the bits organized and easy to find.

There’s a lot to know about benchtop drill presses, and there may be a few new or lingering questions. Check out the answers to some of the most common questions below.

We did dislike that the smaller bits have rounded shanks, as they can be a pain, particularly when the bit is about to drill all the way through the material. However, the large bits have no-spin shanks and do a great job of staying in place. The tips stayed sharp making hole after hole, and they remained cool to the touch during use (while using cutting oil).

Most drill bits are made from HHS, cobalt, or carbide. A bit’s material can influence how effective it is at drilling through different kinds of metals.

There are a lot of handy attachments and accessories available for benchtop drill presses. From sanding kits to mortising chisels, the right accessory kit can turn a standard, run-of-the-mill drill press into a highly functional production machine. Many of these accessories simply tighten in place in the chuck.

This model from Wen was one of the easiest in the bunch to assemble. I also liked that it’s lightweight and compact, allowing for picking it up and moving it with ease. However, the 4208 drill press has two areas of limitation: the ½-inch chuck and its 2 inches of travel. As such, it’s best for light-duty use. And while it doesn’t have a crank to lift and lower the worktable, the affordable price point can buy some forgiveness.

A benchtop drill press is an ideal addition to a workshop, making a clumsy, potentially dangerous job safer and more accurate. Instead of holding a workpiece precariously in hand, users can clamp it to the drill press’s worktable. DIYers can use them for sanding and grinding as well. Some specially designed models, known as mortisers, can even create perfect joinery.

Benchtop drill presses are pretty standard, though there are some differences among brands, sizes, and features. Taking all the above information into consideration, I carefully considered a variety of benchtop drill presses and then performed hands-on testing with the following models to ensure they were top-tier quality.

It’s a bad idea. While you can install a router bit in a drill press, it’s not safe. Drill presses run at much lower rpm, so the bit will likely grab the board and shoot it across the table, possibly leading to injury.

Clamping devices not only hold a workpiece in place for better accuracy but also prevent it from kicking loose and hurting the drill press user. Most of these devices are accessories that users have to buy separately, however.

Pro Tip: When drilling metal, it’s a good idea to keep a can of lubricant or cutting oil nearby. A quick spray on the bit helps to keep the heat down on the tip and maintain a sharp cutting edge.

Home improvement centers often dedicate an entire aisle to drill bits, which come in a plethora of types and sizes for drilling holes in a variety of materials. Many drill bits can pierce through more than one type of material, but not all drill bits can drill through metal without heating up and snapping in half. Labels on drill bits indicate the type of material for which they’re suited, so it’s easy enough to find ones that are designed to drill metal. Depending on the type of metal the user is drilling through, some bits suit the task better than others.

Drill bit coatings affect how a drill bit operates. Most metal drill bits are usually coated with titanium or black oxide. This coating is designed to reduce friction, which keeps the drill bit from heating up and eventually breaking. Because the coating reduces friction, it can also help increase drill speed.

The best way to drill through thick metals is to use a drill press rather than a handheld drill—a press best achieves a clean, smooth hole. Be sure to drill slowly and use cutting fluid to lubricate the bit, too. Let the bit cool down every few minutes to keep it from overheating and breaking.

This model is compatible with Dremel models: 100, 200, 275, 285, 300, 395, 398, 400, 800, 3000, 4000, 4200, 8100, 8200, and 8220.

It’s not a bad idea to clean drill bits after using them. After drilling, wipe away any residue on the bit with a soft cloth and then rub a bit of cutting fluid on it before storing it.

The shank is the nondrilling end of the bit that fits into the drill’s mandrel or “chuck.” For hex shank bits, the shank size of the bit chosen (typically ¼ inch, ⅜ inch, or ½ inch wide) should match the chuck size of the drill.

I really enjoyed working with the Wen 12-inch drill press during the hands-on testing. The motor was quiet, the long travel was a plus, and the digital speed readout on the front of the drill press helped keep track of the speed.

That said, DIYers who are new to benchtop drill press ownership may not be sure of what to look for in a new purchase or even how to operate a drill press. While drill presses aren’t necessarily a niche tool, they’re less prevalent in home workshops than they used to be. Here are some things to consider when looking for the best benchtop drill press for a shop.

When a DIY project requires some precision drill work, only the best benchtop drill press will do. These handy tools are excellent for boring precision holes in wood, metal, and other materials, and modern models have a lot to offer.

This Wen has a laser guide and onboard work light, but it lacks a bit guard for safety. Old-school drillers will appreciate this, but it might be intimidating for new users. However, the one area the Wen could use some work is speed adjustment: The lever was incredibly stiff and difficult to manipulate, even with the drill running. But the worktable, its crank, and the roller certainly made up for it.

The Bosch bits’ tapered tips can quickly penetrate the metal, balance the bit, and produce a clean, even hole. The set includes 21 bits ranging in size from 1/16 inch to ½ inch and is packaged in a plastic storage case.

Wen makes some powerful electric tools, and the 4214 variable speed drill press is no exception. This 12-inch drill press has a digital display, so users always know the exact speed of the drill, which adjusts between 580 and 3,200 rpm in very fine increments. It has 3⅛ inches of travel as well as an adjustable depth stop for repeatable results. The 2/3-horsepower motor has plenty of power for most any shop project, and the worktable is adjustable up to 45 degrees left and right. The table also features a crank handle for raising and lowering.

These bits did a fine job of drilling through our test materials. They didn’t walk when we started the holes, and they bored through the metal at a reasonable pace. The case itself has a cheap plastic tab to keep it shut, but otherwise, it does a good job of keeping these bits safe and organized. They stayed cool while drilling and retained their sharp edges even after several holes. Our biggest complaint is the rounded shank, as the small bits did spin a bit in the chuck.

The ideal horsepower rating for a benchtop drill press is between 1/2 and 3/4 horsepower. These ratings ensure the press is powerful enough to get the job done but still reasonable enough in terms of weight and size to place on a workbench.

One of the best features of the Irwin 29-piece set is the range of sizes available. Each bit increases by 1/64-inch increments between 1/16 and ½ inch, meaning there is a bit for almost any size hole.

Most drill bits fit both standard corded and cordless drills. While these small pieces of metal all look pretty similar, each type of drill bit is designed to make holes in specific materials—including wood, plastic, and metal—but won’t work as well on other materials.

These bits are made for hard use. Their construction is durable, retaining an edge while drilling through thick ¼-inch steel. The no-spin shank prevented the chuck from slipping, boring right through the metal without stopping. They also stayed cool while drilling.

Travel refers to how far the chuck can be moved up and down. For instance, a 2-inch travel means that the user can lower the tip of a drill bit 2 inches. The greater the travel, the thicker material a drill press can potentially drill through.

The 4208 drill press from Wen packs quite a few features into a package with a small price tag. This drill press has five preset speeds: 740; 1,100; 1,530; 2,100; and 3,140 rpm. Its 8-inch throat is large enough for most projects. It has 2 inches of travel, and the worktable tilts up to 45 degrees to the left or right. The 1/3-horsepower motor might seem light by industrial standards, but many DIYers are likely to find it serves their needs just fine.

I found a lot to like about the Shop Fox drill press during the test. First, the wide speed range and high-quality worktable made drilling easy and accurate. Also, I liked the spindle sander attachment as it attaches easily and does a great job of smoothly sanding. My biggest complaint is that the power button is on the left of the machine rather than the front like most other models, which could be a safety issue.

These bits are made from high-speed steel for strength, and they feature a titanium coating for reducing friction and increasing durability. The kit comes with a carrying case with a foam insert with recesses for each bit and a spring-loaded center punch for marking the holes’ locations.

Add a drop or two of lubricating oil to the bit and then grab the broken end of its shank with a pair of pliers. Twist counterclockwise to remove the bit.

Many DIYers don’t bother sharpening their bits when the cutting edges become dull and they have trouble drilling a hole, but it’s tool maintenance worth doing. You’ll get a longer life out of your drill bits if you sharpen their cutting edges with a bench grinder.

When I tested this workstation, I quickly realized that it isn’t for everyone. First, the power and drilling capability falls on the attached Dremel, so speed and control will vary from case to case. But I liked that this model had 2 inches of smooth travel, though the handle did bottom out on the 2×4 I was drilling (which was only 1½ inches thick). When I attempted to drill through steel, the Dremel bogged down immediately, which will probably be typical for most models. Also, I found it important to really tighten down hard on the positioning knobs to achieve accurate drilling.

The first test was assembly, as many large power tools can be difficult to put together. All of these models were fairly straightforward to assemble, with a few being just slightly easier. Next, I tested each by drilling through steel, adjusting the speed, and drilling through wet wood. Next, I checked out all of the additional features to ensure they worked.

DIYers and pros who go through a lot of ¼-inch drill bits for their heavy-duty metalworking projects may benefit from the Drill Hulk’s ¼-inch cobalt steel set. This 12-pack of bits features jobber-style lengths, which means their lengths are relatively long compared to their diameters. They’re made from durable cobalt high-speed steel, feature 135-degree split points for drilling through metal without walking, and have a no-spin shank to prevent them from spinning in the chuck.

DIYers looking for a 10-inch drill press that they can rely on but also lift on and off their benchtop may want to check out this model from Ryobi. This drill press features five adjustable speeds between 620 and 3,100 rpm, and the ½-inch chuck has a travel of 2⅛ inches, allowing this relatively compact model to handle some bigger drilling jobs. I really liked this model from Ryobi. The laser was bright and easy to see, even with the onboard light turned on. I also really liked that this model’s worktable had a crank system, as many smaller drill presses don’t. While my particular model did chatter a bit, the compact and lightweight design made it easy to lift on and take off the bench.

Whether you’re just getting into metalwork or you want to expand that drill bit set, adding metal drilling bits to an arsenal of tools is a good investment. If drilling through metal is a new endeavor, there may be some questions that need answering.

While we’re not huge fans of general-purpose bits typically, especially when it comes to drilling metal, these Bosch bits were excellent. They didn’t walk when starting a hole, and they removed long shavings of metal, proving they remained sharp while drilling. We were so shocked that these bits were this good that we kept drilling with them to see if it was a fluke. They drilled holes faster than the other bits in the test, which really surprised us.

Avid metalworkers looking for a quality drill bit set for their metal projects may want to upgrade to the Irwin 29-Piece cobalt-alloy steel drill bits set. This set includes 29 drill bits from a 1/16-inch bit to a ½-inch bit, with bits larger than ⅜-inch wide having reduced-size shanks so they can fit smaller chucks.

It depends on what kind of metal you’re drilling through. Titanium bits are suitable for drilling through soft metals such as aluminum, while cobalt bits are better suited for drilling through hard metals like cast iron.

Those looking for an all-around capable set of drill bits may want to check out the Bosch black oxide metal drill bit set. Manufactured from high-speed steel and coated in black oxide, Bosch drill bits can withstand friction and heat so you can drill continuously without the bits heating up.

When looking for a set of high-quality drill bits for metal, you may want to consider the Irwin 63137 set of bits. Made from cobalt high-speed steel, they’re designed specifically for hardened steel. They have 135-degree split-point tips, helping them to resist walking when starting a hole. They also resist wear and heat, making them a solid choice for drilling through metal materials. Bit sizes range from 1/16 to ½ inch wide, and the bits larger than ⅜ inch wide have reduced shanks.

Horsepower is a nice-to-know number, but it’s not as crucial for workshop benchtop drill presses as it is for floor models in production settings. Speed variability is far more important than horsepower when it comes to a benchtop drill press.

Shop Fox knows that most hobbyists need their workshops to be as versatile as possible. The brand’s 13-inch benchtop drill press/spindle sander is designed for both drilling and sanding, which is why this 3/4-horsepower drill press turns the spindle at speeds between 250 and 3,050 rpm. The 13¼-inch swing allows easy manipulation of large workpieces without issue, especially when sanding.

Folks who need to drill a few holes in some metal surfaces but don’t want to break the bank on a set of expensive drill bits may prefer the DeWalt DWA1184 black and gold drill bit set. This set of all-purpose bits can drill wood, plastic, or metal and features 135-degree split-point tips to help prevent walking.

My favorite is the Wen 4214 5-Amp 12-Inch Variable Speed Drill Press. The motor is quiet, and it comes with an integrated laser and light as well as a digital speed readout. To make sure all of these benchtop drill presses have what it takes, I performed hands-on testing with all of the following models. Keep reading to learn about what I liked and what I didn’t.

These drill bits are made from durable cobalt-alloy high-speed steel, helping retain a sharp edge while drilling. They all fit inside the sturdy hinged case with a spring-loaded latch to keep the kit closed when not in use. The case also has a tap guide inside to help you identify which bit to use for a particular bolt or fastener.

Drill presses commonly come with speeds varying from 200 to 3,600 rpm. Generally, the harder the material, the lower the required speed. This reduces the heat generated by the drill to help maintain a sharp cutting edge on the bit. Some materials require higher speeds than others. For instance, drilling through pine at a high rate is fine, a piece of oak requires a medium rate, and various metals require low rates of speed.

Jet tools are just as at home in a production setting as they are in a DIY workshop, and that includes this powerful benchtop drill press. The J-2530 from Jet has a 15-inch throat and 3/4-horsepower motor for drilling through some serious materials. The worktable tilts 45 degrees left and right and swivels up to 360 degrees when the user needs it out of the way. The motor has 16 speeds, adjusting from as low as 200 rpm to as high as 3,630 rpm. It has a 3⅜-inch travel to complement its wide throat. It also features an oversize on/off switch and a bit guard.

To bolster my own research, I interviewed Paul Kropp, a master woodworker and the co-founder and COO of Bakes & Kropp, a nationwide kitchen design and cabinetry company, who gave his insight on the use of benchtop drill presses in a professional setting. His main advice to shoppers is to look for “adequate horsepower to spin a big hole saw or Forstner bit … and solid pivot points for adjustment.”

Finally, I considered the saw’s weight, size, and price, and I assigned awards to the models that passed my tests. The result is this list of some of the best benchtop drill presses on the market today.

Standard benchtop drill presses range from 1/3- to 3/4-horsepower models. Either will do for most workshop-based projects. If a drill press starts to bog down, the user is putting too much pressure on the bit. This is bad for the bit, the chuck, and the spindle, so lighten up.

Researching shank design, bit material, and bit coatings can be confusing, but fortunately, drill-bit manufacturers make shopping relatively easy for the customer. Drill bits are labeled not only by the size of the hole they’ll drill but also by the type of materials they’ll drill.

First, we drilled into some relatively light-duty 11-gauge steel angle iron, testing a few bits from each pack. We wanted to see how well they’d retain their edge, how hot they’d get, and how long it would take them to bore a hole in the metal.

According to Kropp, these tools are “an excellent way to utilize the precision of a drill press in a compact footprint,” so shoppers with limited space in their workshop can still tackle projects that require a drill press without it taking up the entire space.

We tested these Top Picks products to ensure that they had what it takes for drilling metal. To qualify as one of the best drill bits for metal, the bit needed to perform well in the metal that it’s designed to drill. Bits also need to be durable and able to withstand the friction and heat produced when drilling through metal. The following recommendations are all at the top of their class for metal drilling, and one (or more) may be an asset to your tool collection.
