About Drill Bits

Drill Bits

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

Short-Length Drill Bits

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

Extended-Length Drill Bits

Short-Flute Extended-Length Drill Bits

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

Maintenance-Length Drill Bits

Also known as mechanics' bits, these are shorter and more rigid than jobbers’ bits but longer than short‐length bits.

Chip-Clearing Drill Bits

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

Extended-Length Chip-Clearing Drill Bits

Cobalt Steel Drill Bits

Short-Flute Cobalt Steel Drill Bits

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

Short-Length Cobalt Steel Drill Bits

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

Extended-Length Cobalt Steel Drill Bits

Short-Flute Extended-Length Cobalt Steel Drill Bits

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

Chip-Clearing Cobalt Steel Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Carbide Drill Bits

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

Short-Length Carbide Drill Bits

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

Smooth-Finish Carbide Drill Bits

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits.

Carbide Drill Bits with Coolant Holes

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology.

Chip-Clearing Carbide Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Extended-Length Carbide-Tipped Drill Bits

Short-Flute Extended-Length Carbide-Tipped Drill Bits

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

Carbide-Tipped Drill Bits

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

Short-Length Carbide-Tipped Drill Bits

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

Hex-Shank Drill Bits

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

Threaded-Shank Drill Bits

All have a 1/4"-28 threaded shank which installs directly into the threaded spindle on a compatible drill.

Drill Bits for Wood Screws

These bits are cut to match a wood screw’s thread and diameter, resulting in a perfect fit for a screw. They produce clean edges when cutting soft and hard wood.

Carbide Drill Bits for Hardened Steel

Harder, stronger, and more wear resistant than carbide-tipped steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

Drill Bits for Plastic

The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.

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.

Cobalt Steel Drill Bits for Stainless Steel and Nickel

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Carbide Drill Bits for Stainless Steel and Nickel

Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

Drill Bits for Aluminum, Brass, and Bronze

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.

Reversible Drill Bits for Sheet Metal

When one end becomes worn, reverse the bit to use the other end.

Drill Bits for Sheet Metal

These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing.

High-Speed Steel Left-Hand Drill Bits

Use for drilling in most metal.

Drill Bits for Countersunk Holes

Hex-Shank Drill Bits with Guide for Countersunk Holes

Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank.

Round-Shank Drill Bits with
Guide for Countersunk Holes

The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit.
