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.

Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Also known as double-margin drill bits.

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

Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. Also known as brad-point bits.

The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.

Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.

Use for drilling in most metal.

Lock your bit into the adapter to prevent accidental disengagement. These adapters hold hex-shank bits (also known as insert bits) in powered tools.
