Dull drill bits can increase time and effort needed to complete work and possibly damage the materials you’re working on, and may even cause injury.

Also known as high-speed bits, they resemble corkscrews and are some of the most popular bits. They are typically used to drill small holes into wood and walls. Their unique design allows them to channel dust from the hole as they work.

Although a bit pricey, these drill bits have an extra 5 – 8% cobalt, making them more resilient, sharper, and heat resistant.

Black oxide is suitable for drilling iron and steel but is not recommended for drilling aluminum, magnesium, or similar materials.

These are special types of bits that can drill through plastic, tiles, glass, marble, and brick. They can also withstand high temperatures.

Drill bits are cutting tools. If you do a lot of home projects or heavy-duty construction work, periodically sharpening your drill bits will be necessary.

Black Oxide: The most economical coating. Black oxide adds corrosion protection, increases tempering and stress relieving of the bit, reduces galling and chip welding, and aids in retaining drilling lubricants.

You use a hammer bit to create precise holes into concrete slabs when looking to determine the amount of humidity in a concrete slab.

Used to drill larger thru-holes in metal (7/16″ and up), these bits require a special machine. Similar to a hole saw, annular cutter bits cut the outer diameter of the hole and leave a solid center slug.

Drilling holes in hard metals is not as difficult as it may seem. By using the right tools, lubrication, and technique, you can achieve perfect holes without any trouble. Remember to take your time when drilling and to apply firm and steady pressure for the best results.

Auger bits have a screw tip that creates the initial hole for the rest of the bit to fall. As a result, holes by auger bits are incredibly clean and precise.

These are what you use when looking to create holes in bricks, stones, or concrete. Due to the tough nature of those materials, masonry bits wear out quickly, meaning that you will need to replace them frequently.

Named after their tip that resembles a series of pyramid-shaped steps, these bits are what professionals use to drill into sheet metal. Their stepped design allows you to create holes with varying diameters. Step bits are renowned for their versatility.

Sized for their diameter, drill bits are constructed in a range of styles to help with specific tasks. Not sure which drill bit you need or what you need in your toolbox? Keep reading for a rundown of the different types of drill bits you’re likely to come across.

If you are a DIY enthusiast who loves working with metals, you probably have encountered the difficulty of making holes in hard metal. It is not an easy feat, but with the right tools and techniques, you can make perfect holes in any type of hard metal, whether it’s aluminum, steel, or something else entirely.

Drill bits made from cobalt blend or black oxide are most suited for hardened metals. Bits made from black oxide are of superior quality and last 50% longer than high-speed steel (HSS).

As their name implies, these bits can be adjusted to create holes of varying sizes, thus eliminating the need for purchasing bits of different sizes.

The tip of the bit has a tiny hole where you insert the wire you are looking to pass through the material. Installer bits are incredibly long, reaching lengths of up to 18 inches to facilitate their work.

Typesof drillbits and their uses

Most drill bit sets are sold in a case with space to hold each bit in place. This keeps the drill bits from being nicked or scratched and also provides excellent organization.

A pilot hole is a small hole you drill before making the actual hole. The pilot hole helps to ensure that your bit doesn’t wander when you start drilling the larger hole. It also helps to prevent the bit from slipping and breaking.

Proper drill bit maintenance is not much different from maintenance for most tools, and it helps prolong the life of your drill bits and keeps them ready for the next job.

A sharpening tool can be a good investment to keep your drill bits in top shape. More experienced DIYers can accomplish the task with a good set of grinding tools.

Like auger bits, self-feed bits also feature a screw tip for positioning the bit. They create clean, precise holes, as well. However, since they do not channel the dust away from the hole as they work, you must halt the operation periodically to clear the dust away.

Less powerful drill presses are sufficient when working on softer metals. However, hard metals like cast iron and hardened steel require powerful drill presses that can manage the extra torque.

Some people don’t find it necessary to use a lubricant when drilling softer metals. Drilling hard metals require cutting oil or a multi-purpose oil for lubrication. Lubrication makes the metal drilling process easier and helps your bits remain sharp by reducing friction and keeping the bits cool.

To meet the needs of both wholesale and retail customers by providing an extensive selection of metals cut to size with exceptional service.

Setting the right speed and applying the appropriate downward pressure when drilling is vital. The rule of thumb in drilling is to slow it down as much as possible.

Also, as you drill slowly, apply a downward pressure that is firm and steady enough to produce long shavings. If you are getting tiny shavings or dust particles, it’s a sign that you are not applying enough pressure or that the drill tip is dull and in need of re-sharpening.

Jul 15, 2024 — A low taper fade haircut is a popular men's style where the hair is cut short near the neck and gradually fades up to longer hair on top.

Titanium Nitride (Tin): A more expensive coating that increases the hardness of the bit and provides a thermal barrier resulting in increased production rates and longer tool life in harder materials.

Plug cutters are helpful in professional projects, as they drill holes into the wood while cutting the wood plugs you require to hide recessed fasteners.

Drill bits made for steel, aluminum, copper, cast iron, sheet metal, fiberglass, brick, vinyl flooring, and more are also available.

When it comes to drills, there are two easily identifiable parts you need to know about – the shank and the chuck. Here’s a little information to help you understand more about how drills and drill bits work:

These bits have a special design that allows them to drill a hole into a material with the purpose of extracting its core.

These are what you use when looking to bore smooth and clean holes into the woods. This bit also comes with a pointed tip to allow for easy positioning of the bit.

Most drill bits are made using high-speed steel and can drill effectively through most metals, including other materials like plastic and wood. However, if you need to drill holes through hard metals, you will require a different bit.

Brad-point bits come in handy when you need to make clean and precise holes. They come with rubber stoppers to allow you to set a particular depth. Their precision makes them a popular bit among woodworkers.

Bronze Oxide: Bronze oxide increases the tempering and stress relieving of the bit and is generally used alone to visually identify cobalt steel or with black oxide to identify better grades of high-speed steel.

The chuck is the part of the drill that attaches the drill bit. Most power drills for home use have a 3/8-inch or 1/2-inch chuck. Larger chucks come in 5/8-inch and 3/4-inch sizes but are usually fitted on heavy-duty and industrial power drills and drill presses.

Spade bits have a spade-shaped tip that allows them to bore into softwoods. They are typically used to create holes for running cables.

As mentioned earlier, drilling through tile requires a specialist drill bit – regular or even masonry bits simply won’t do the job as they’re not strong enough to penetrate tiles’ hard surfaces. Instead, you should opt for either carbide-tipped or diamond-tipped drill bits.

If your set didn’t come with a case or you’ve been buying individual drill bits, add a storage box with dividers to your toolset. Don’t store more than two bits together and use a permanent marker to mark each space with the size and type of drill bit stored there.
