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

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

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

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.

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

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

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.

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.

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

Use for drilling in most metal.

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

For general purpose use.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.

These countersinks create a surface that minimizes contact between the material and the lathe centers to prevent damage and allow for more precise machining.

For excellent performance on hard and abrasive materials, these carbide countersinks are harder, stronger, and more wear resistant than cobalt steel and high-speed steel countersinks.

For use on wood and plastic.
