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 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.

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

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

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

Access hard-to-reach spots and drill deep holes.

More wear resistant than cobalt steel and high-speed steel, carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.
