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

Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

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

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life. A split point keeps the bit centered without a pilot hole.

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

These jobbers'-length bits have the rigidity and length required for most applications. 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. A split point keeps the bit centered without a pilot hole.

In addition to resisting heat and wear better than high-speed steel drill bits, these can also run up to 25% faster and have a longer tool life. Insert them into power screwdrivers, impact drivers, and other tools that accept hex shanks. The flat surfaces on the hex shank allow tool chucks to grip these bits more securely than those with a round shank. A split point keeps the bits centered without a pilot hole.

A built-in stop ensures repeatable drilling depths for installing drop-in anchors. 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.

Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. The center guide point prevents the bit from wandering. Also known as brad-point bits.

High-speed steel drill bits are stronger and more wear resistant than steel drill bits.

The straight flutes and notched point withstand the heavy pressure necessary to penetrate hard steel. These carbide-tipped bits maintain their sharp edges when drilling abrasive material. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. They are jobbers' length and have the rigidity and length required for most hand-held drilling and machine tool applications.

Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits. They are jobbers' length and have the rigidity and length required for most applications.

Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are jobbers' length and have the rigidity and length required for most applications.

Also known as step drill bits, these bits countersink as they drill. The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws. After multiple sharpenings, the drill bit diameter may become smaller.

Choose fewer flutes for a faster cut or more flutes for a smoother finish. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.

Choose fewer flutes for a faster cut or more flutes for a smoother finish. The 60° countersink angle is compatible with the profile of centers on a lathe.

Often called step drill bits, these drill and counterbore holes at the same time. After drilling and counterboring, tap the hole and install your fastener. The body diameter may decrease after multiple sharpenings.

These counterbores are often used when screw holes in sheets or layers are misaligned. Also known as subland drill bits, they last longer than standard counterboring drill bits because the diameter stays the same after sharpening. They drill and counterbore at the same time. After drilling and counterboring, tap the hole and install your fastener. The diameters account for the 1/32” or 1/64” oversized diameter rating.

These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
