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.

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.

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.

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.

1/2" Diameter Reduced-Shank Drill Bits

Cobalt Steel 1/2" Diameter Reduced-Shank Drill Bits

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.

Cobalt Steel 3/4" Diameter Reduced-Shank Drill Bits

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.

3/8" Diameter Reduced-Shank Drill Bits

Cobalt Steel Morse Taper-Shank Drill Bits

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.

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.

Cobalt Steel Hex-Shank Drill Bits

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.

Hex-Shank Masonry Drill Bits
for Tapping Screw Installation

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

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 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.

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.

Left-Hand Drill Bits

High-Speed Steel Left-Hand Drill Bits

Use for drilling in most metal.

Cobalt Steel Left-Hand Drill Bits

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.

General Purpose Drill Bit Sets

Drill Bit Sets

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

Maintenance-Length Drill Bit Sets

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

Short-Length Drill Bit Sets

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

Chip-Clearing Drill Bit Sets

Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.

Cobalt Steel Drill Bit Sets

Short-Flute Cobalt Steel Drill Bit Sets

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

Short-Length Cobalt Steel Drill Bit Sets

Cobalt Steel 1/2" Diameter
Reduced-Shank Drill Bit Sets

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.

High-Speed Steel 1/2" Diameter
Reduced-Shank Drill Bit Sets

Use these bits for general purpose drilling in most material.

Hex-Shank Drill Bit Sets

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