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.

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

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

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

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.

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

These bits have a round or hex shank that fits into the three-jaw chuck on a hammer drill.

A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.

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.

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

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.
