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

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.

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

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.

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.

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

These bits are cut to match a wood screw’s thread and diameter, resulting in a perfect fit for a screw. They produce clean edges when cutting soft and hard wood.

Carbide-tipped bits maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

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

Harder, stronger, and more wear resistant than cobalt 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.

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.
