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.

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.

Drill long, straight holes with these bits. Channels in the bit allows coolant to flow through the tool for more efficient chip evacuation. Also known as gun drills.

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

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.

In addition to resisting heat and wear better than high-speed steel drill bits, these can also run up to 25% faster and have a longer tool life. Insert them into power screwdrivers, impact drivers, and other tools that accept hex shanks.

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

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

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.

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

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

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.

Harder, stronger, and more wear resistant than high-speed 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.

With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life.
