Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Also known as double-margin drill bits.

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

These jobbers'-length bits have the rigidity and length required for most applications.

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.

Use these bits for general purpose drilling in most material.

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.

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

The 1/4" hex shank allows these bits to be used with standard impact drivers.

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.

Multiple outlining teeth bore clean, flat-bottom holes without chipping or splintering your surface—even when cutting across the grain. Also known as multispur bits.

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

Carbide-tipped bits maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

These jobbers'-length bits have the rigidity and length required for most applications.

A quick-change mechanism allows fast bit changes.

Also known as step drill bits. The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws.

Often used with screw holes in misaligned sheets or layers of material.

Strong and durable, these multipurpose bits are for use with bit screwdrivers.

The toughest bits available, these withstand the shock and twisting force of impact drivers.

Ribs forged into the wings of these bits grip the screw recess to reduce stripping. They're also known as ACR® bits.

The small-diameter shaft can access screws in narrow recessed holes.

Strong and durable, these multipurpose bits are for use with bit screwdrivers. They're designed for screws with a square recess in the head and are also known as Robertson bits.

An opening at the tip accommodates the pin in the recess of tamper-resistant hex screws. These are also known as pin-in-hex or pin-in-socket bits.

A magnet or retaining ring holds the nut in place.

Use hex-shank bits (also known as insert bits) in powered tools.
