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.

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

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.

An open spiral-flute design clears chips quickly, so these bits can bore smooth, deep holes through construction lumber, railroad ties, and utility poles. Also known as pole or ship auger 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.

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

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.

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.
