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.

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.

These are the bits to use when looking to drill into thick and dry wood. Thanks to their innovative design, you do not have to apply a lot of pressure when drilling into tough materials. 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.

Composite end mills from Karnasch Tools are designed for high performance in a variety of materials. Composite end mills are made from a combination of materials such as high-speed steel, polycrystalline diamond, and ceramics. This combination provides excellent performance in both hard and soft materials. The unique combination of materials allows the end mills to cut faster and last longer than conventional tools. Additionally, the composite end mills are designed with optimized geometry that reduces vibration and enhances cutting performance.

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.

You can also determine the size of the drill bit based on the screws you want to use. The diameter of the hole you drill should be slightly smaller than the diameter of the screw. So, for example, if you’re using a 3.5 mm screw, use a drill bit with a diameter of 3 mm.

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. Each spot is marked for the bit’s size and type, making it easy to quickly find the right bit for the project you are completing.

Drill bits are generally classified as Twist Drill, Counterbore, Countersink, Flat Bottom Boring, and Specialty. On our web site we have divided these into two categories: Drill Bits – Normally used with hand held drills or drill presses fitted with standard chucks.

Quarter-inch hex shank bits are intended to be used on 1/4-inch impact drivers and can be quickly changed. SDS (slotted drive system) shanks are used for concrete drills and demolition bits and work specifically with SDS-Plus and SDS-Max rotary hammer drills.

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.

A twist bit is the most common type of drill bit for home use. It works for general-purpose drilling in wood, plastic and light metal.

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.

Cutting

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

Milling machine

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. Caring for your drill bits can also be a matter of safety; dull or damaged drill bits can create problems both in the work and for the worker.

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.

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. 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.

When choosing a drill bit set, go for an HSS, cobalt, or carbide set. These bit types will perform well on different materials and surfaces, including wood and metals. Cobalt and carbide bits are also good for heavy-duty drilling into hard steels, metals, and concrete.

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

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.

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.

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

Things You Should Know1. A wood drill bit has a pointed spur on the tip. A metal drill bit comes to a blunt point.2. Metal drill bits may have a black or gold coating. Wood drill bits usually have a shiny silver finish.3. It’s safe to use a metal drill bit for wood but it may create rough edges around the hole.

Drill bits are designed to drill holes in a variety of different common materials. These include different types of wood, metal, plastic, ceramic tile, porcelain, and concrete. Drill bits made for steel, aluminum, copper, cast iron, sheet metal, fiberglass, brick, vinyl flooring, and more are also available.

Professionals use installer bits to bore holes for installing wiring for entertainment or security systems. 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.

Bronze Oxide: Bronze oxide increases 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.

Carbide

High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Cobalt drill bits are extremely hard and dissipate heat quickly. They’re mostly used for boring in aluminum and tough metals such as stainless steel.

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:

Helical

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.

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

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

The shank is the end of the drill bit that fits into the drill and is secured by the chuck. A round shank helps to center a bit in the chuck more accurately. The flat surfaces on a hex shank allow the chuck to grip the drill bit more securely.

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. Tin also provides the same benefits as black and bronze oxide. Tin-coated bits are suitable for drilling iron and steel as well as aluminum, magnesium, etc.

These bits come with carbide tips to allow you to bore holes into tiles without creating chips or cracks in the tile. Different tile bits are designed for different types of tiles. Therefore, ensure that you check its package to confirm that it can drill into your tiles.

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.
