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.

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.

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

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

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.

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.

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.
