These drill bits also allow you to counterbore holes and drill in at the same time using different types of drill such as a glass drill, msonry drill, or even a handheld drill.

Before we go into detail on different drill bits, let’s first review exactly what a drill bit is. Drill bits are essentially cutting tools that are attached to either a drill press or a manually operated drill.

A drill bit is attached via a drill chuck in order to drill holes- which is a clamp that will hold the drill bit in place- and are used to make holes or enlarge holes within various materials, such as solid metal and wood using a drill bit.

6. Installer drill bits are a special type of twist bit used for wire installation. They can be long and they can drill through a variety of materials. Once through the surface, you can put a wire into a small hole in the bit and use the bit to draw it back through the hole. Then you can attach the wire to an additional wire and pull it through the hole.

11. Forstner drill bits are good for drilling flat-bottomed holes in wood that can hold dowels. The bit has a point for precise positioning. Best used with drill presses that allow force and control.

First off, what is the difference between metal and wood drill bits—or plastic, glass or ceramic tile for that matter? There are many ways to answer that question—from the bit design and tip angle to the length and flute design. Let’s start with the most fundamental aspect of drill bits: the metal compositions and finishes, since that has a huge role in what materials a bit can handle, how hot it can get and how it will perform overall.

Flutes are the spiral grooves cut into the drill bit. A fast spiral has more twists per inch and facilitates large amounts of swarf (shavings) at low drill speeds. A low spiral has less twists per inch and is used in high-speed drilling where swarf is expelled quickly. Standard twist drills tend to have two flutes with low spirals. The part of the bit where the flute ends and transitions into the part inserted into the drill is called the shank. The shank can be cylindrical, or for a tighter grip and more torque, it can be hex or slotted drive system (SDS).

Made from all kinds of metals, these drill bits feature a cutting edge on the bottom end with a twisted groove that is cut onto the body and runs from the top to the bottom (also known as the flute).

These drill bits have a look that resembles that of a brad nail, hence their name. They also feature two spur cutting edges that allow for less splintering on wood, which is why they are primarily used in woodworking.

15. Tile drill bits typically have a hard and sharp carbide tip that can drill holes in tile without causing chips and cracks.

9. Auger drill bits are wood-borers with screw tips that start holes easily and pull bits through the material quickly. They come in long sizes and have big flutes to aid in sawdust removal.

It pays to choose the right drill bit for your project. Picking the right one is all a matter of knowing the basic drill bit features, the types of drill bits out there and the metals and finishes that make a difference. That and a few tricks of the trade and you can make perfect holes anywhere and every time.

These drill bits have outer teeth that are able to cut perfect holes, similar to hole saw drill bits. They also have a radial blade that can slice out the core, similar to that of a spade drill bit. They feature a threaded tip too, allowing the user to pull the drill bit through the wood.

These are drill bits that are great for general-purpose DIY, designed to create accurate and clean holes in materials such as plastic, wood, and metal.

4. Countersink drill bits are used to create a conical surface hole with a smaller hole in the center to allow a screw to sit flush with a metal or wood surface.

2. Step drill bits are good for drilling metal up to ¼” thick as well as wood. The beauty of these cone-shaped bits is they enable you to use one bit to drill holes with different diameters. They are useful in enlarging holes in sheet metal.

12. Plug cutters bore holes into wood, creating leftover plugs that can be replaced over the tops of screws to conceal them.

They are woodworking drill bits that are often used by professionals, such as electricians or plumbers, in order to drill holes in walls for wires or pipes.

Usually made from either high-speed steel, carbide, or carbon steel, Brad Point drill bits are similar to twist drill bits, but they feature a long and sharp point at the end.

They can be used for a variety of purposes, including making holes in walls for plumbing, drainage pipe installation, or cutting masonry.

These drill bits- also called step drill bits- are used for making existing holes larger so that screws are able to stand more firmly when placed within the hole. They lead to smooth holes that are perfect when working with softer materials and thin sheet metal.

Augers have a screw top which not only helps to make the hole but also makes it easier to create a clean hole when you are pulling the drill bit out.

Another drill bit that is used for boring holes, installer drill bits are designed with a flute that has a hole in it so that wire can be pulled through it, making them ideal when it comes to installing devices with wires such as phones, security systems, or computers.

7. Spade drill bits are typically used to drill large holes in wood—up to 1-1/2”. The flat blade has a sharp point at the lead to position and guide the bit.

1. Twist drill bits are the classic drill bit for everyday use. Depending on their composition and coating, twist drill bits are the go-to for most metal-, wood- and plastic-drilling jobs. A comprehensive set of twist drill bits is a must for any garage.

If you find yourself struggling to know which drill bit to use for what, then keep reading, as we are going to be going through twenty of the most common drill bits and taking a look at exactly what each drill bit is used for when it comes to drilling holes!

These durable and tough drill bits are usually used for high-volume production drilling, which involves very quick and repetitive drilling. They are also incredibly versatile as they tend to be used to work on all kinds of metals.

Many of the mishaps related to drilling are the result of the wrong choice of drill bit. They are not all the same. Far from it. Knowing the differences and intricacies of their design can help lead you down the straight and narrow path of success in drilling holes in any material.

Rivet drill bits are unique in that they are able to drill precise and short rivets into sheets of metal plates, even when they are especially thin sheets. This makes them particularly popular amongst professionals that have this specific need.

The drill bits themselves have two features that make them stand out, that being their wider countersink area and their narrow pilot point which makes it really stand out amongst all of the many types of drill bits like masonry drill bits, an auger drill bit, or a countersink drill bit.

14. Masonry drill bits are made with formidable carbide tips to put holes in brick, concrete and other tough substrates. Some work with standard drills; others are designed to be used with rotary hammer or hammer drills.

5. Counterbore drill bits create flat bottomed larger holes on top of smaller holes so that the screw can be hidden lower than the surface. They are good for wood or metal substrates.

3. Hole saws aren’t technically drill bits, but they cut big holes using a drill—and they’re very useful in the garage for making holes for hoses and wires. They have a toothed blade in the shape of a circle. Bi-metal hole saws can cut metal. Ones made of carbide can cut ceramic tile or masonry—and with a diamond edge, you can do it even quicker.

These drill bits have either flutes or grooves that run parallel to the axis of the drill, and they are usually used when it comes to drilling copper, brass, and materials that are softer, allowing them to be drilled into without the worry of the drill digging too aggressively into the metal.

There are more drill bits available too, but hopefully, our list has given you enough variety when it comes to drill bits so that you can find the perfect one to suit your DIY needs!

Is it worth it to sharpen bits? When bits are dull, they often break because people tend to apply too much pressure on them—not safe and not cost effective. Keep your bits sharp by using a sharpening tool or the fine grit wheel of a bench grinder. When drilling metal, drill bits can also snag when emerging through the bottom side. So ease off the pressure at the end and try putting a block of wood underneath to prevent the metal from pushing out, snagging your bit and breaking it. Also prevent your bits from becoming chip magnets. Use a demagnetizing tool to prevent metal swarf from sticking to the bit, creating friction, clogging flutes and pitting your cutting edge.

Drill bits are an essential part of any DIY project that involves a good amount of drilling, but there are so many different drill bits that it can be a little overwhelming if you aren’t well versed in the subject and you don’t know which drill bit to choose to start drilling holes.

Also known as hole drill bits or hole cutters, these attachments are designed specifically for creating perfect, round holes in a range of different materials.

Annular drill bits are used for drilling metal and are able to cut grooves at the periphery of the hole that is cut into the metal, as well as extract the metal core at the center.

Typesof drillbits and their uses

Different drill bits can be used with different materials, as we will go into in this list. So without further ado, let’s get started and take a look at the different types of drill bits.

8. Brad-point drill bits are for wood. The brad-point in the middle of the bit is there to aid precise positioning and ensure a clean exit hole. Wide flutes evacuate large amounts of swarf.

13. Glass drill bits have carbide tips shaped like arrowheads. Successively larger bits are often used to increase hole sizes.

The drill has got to be one of the most useful tools ever created. Every fleet garage and heavy-duty repair shop needs holes…just not bad holes, misplaced holes or any of the accidents or injuries that can come from drilling holes.

10. Self-feed drill bits are also wood-borers but they’re smaller and don’t have large flutes to evacuate swarf. The screw tip design helps position the bit and draw it down easily.

These drill bits are used purely for wooden surfaces, more specifically for when a plug needs to be cut out. However, they are also useful when it comes to making a specific hole within a wooden surface.

Designed for quick drilling through materials that are brittle- such as concrete- hammer drill bits combine a pounding, hammer-like action with the rotary action of the drill.

With a sharp, pointed center, Forstner drill bits have a range of different applications, though they are mostly used for woodworking thanks to being a large bore drill bit.

Finally, these drill bits are incredibly handy when you need to create different hole sizes as they can adjust accordingly, minimizing the need to buy multiple drill bits.

The most commonly used drill bit, twist drill bits are able to cut through a wide range of materials such as plastic, concrete, steel, and wood.

Bullet Pilot Point drill bits have a tip that is designed to immediately enter the drilled-in material on contact, without any irritating walking.

Used to create a cone-shaped depression within wood, countersink drill bits can create a recess that is able to let a countersink bolt sit completely flush with the material surface Which is great if you want to create a really secure drill hole even when creating large holes in soft metals .

They can be used with wood, metal, or plaster. The three fluted shank of the drill bit helps to prevent the chuck of the drill from slipping as you drill.

Choosing the right drill bits supports precise and productive work. It also helps protect the value of the parts and materials you work on—which can help keep your operation out of the hole, financially speaking.

This twisted flute is what gives the twist drill bit its name. They can be used with a drill press, hammer drills, or even thick drills and electric drills.

Dowelling drill bits feature four spurs as well as sharp corners that can immediately pierce wood. They also have a lip at the center that maintains the stability and level of the material whilst being drilled.

With the right drill bit, the most indispensable tool in the shop, can be made even more useful. Imperial Supplies is here to help you make every hole a success by building an arsenal of bits that arms you for any task. Let us know how we can help!

Now that you know the basic attributes of drill bits, it’s time to go deep on the right design for the substrate, or material, you’re working with. In the heavy-duty world, technicians need to drill holes in a wide range of substrates from hard and soft metals to glass, plastic, wood—and maybe even tile or concrete when odd repairs and improvements come up. Having the right drill bit, sharp and ready, can make the difference between a ruined part or a speedy repair. Use this helpful list to make the right choice.

One of the main questions people ask is “what is the difference between 118- and 135-degree drill bits?” There are three main variations of drill bit tips. A 118-degree point is primarily for wood or plastic where entry is easier. A 135-degree point is used for drilling holes in metal and harder surfaces to eliminate the bit from sliding or skating. The third is a split point. Are split-point drill bits better? Split point bits have small cuts on either side of the cutting flutes on the tip to bite in faster and prevent skating.

Center drill bits are used with a center drill, which is in turn used to center a hole and ensure that this is done accurately when drilling wood.
