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

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

Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.

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.
