Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than standard-length drill bits. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

Drill bits with a split point keep centered without a pilot hole.

Drill bits with 135° point angle produce smaller chips than 118° point to prevent clogging.

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.

Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.

Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers. These bits cannot be used with SDS-Max-drive rotary hammers. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers. These bits cannot be used with SDS-Plus-drive rotary hammers. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also known as percussion or impact bits.

The shank has 12 splines for use with a spline-drive rotary hammer. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits drill faster and penetrate material with less pressure than rotary-only bits. Also called percussion or impact bits.

A more controlled chip removal reduces heat buildup, making these bits good for use on brittle material such as block and brick. Instead of using a hammering action to break up masonry material, they drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications.

When you encounter rebar, stop drilling and mount one of these bits in your tool. Drill through the rebar, and then resume drilling with your masonry drill bit. The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers set to rotary-only mode. These bits cannot be used with SDS-Max-drive rotary hammers. Do not use in hammering applications.

When you encounter rebar, stop drilling and mount one of these bits in your tool. Drill through the rebar, and then resume drilling with your masonry drill bit. These bits drill holes using rotary action only and should not be used in hammering applications. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode.

When connected to a vacuum, these hollow bits can suck up concrete dust while drilling to help meet OSHA standards for silica dust exposure. They can also be used to clean out holes for installing adhesive anchors. The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers. They cannot be used with SDS-Max-drive rotary hammers.

Also known as spade bits, these have a centering point and two cutting edges for boring holes in hard and soft wood.

With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life. Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
