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.

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.

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.

Access hard-to-reach spots and drill deep holes.

More wear resistant than cobalt steel and high-speed steel, carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

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

A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.

Use these bits with handheld power drills and hammer drills set to rotary-only mode.

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.

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.

Use for drilling in most metal.

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.

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.
