About Drill Bits

Compare material, finish, length class, and decimal size equivalents.

Fabricating and Machining

Masonry Drill Bits for Drilling Rigs

Use these diamond-coated hollow bits for wet drilling of masonry, concrete, and rebar with a drilling rig.

Drill Bits for Carbon Fiber, Fiberglass, and Graphite

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

Short-Length Drill Bits for Carbon
Fiber, Fiberglass, and Graphite

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

Core Drill Bits for Glass and Ceramic

These hollow bits are diamond-tipped for long life and fast cutting speeds. Only for use in drill presses.

Diamond-Coated Router Bits for Composites

With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits.

Screwdriver Bits and Adapters

Phillips Bits for Impact Drivers

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

High-Torque Phillips Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Hex Bits for Impact Drivers

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

High-Torque Slotted Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Torx Bits for Impact Drivers

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

High-Torque Torx Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Square Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers. Designed for screws with a square recess in the head, they are also known as Robertson bits.

Pozidriv® Bits for Impact Drivers

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

High-Torque Bit Assortments

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Bit Assortments for Impact Drivers

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