About Drill Bits

Drill Bits

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

Cobalt Steel Drill Bits

Chip-Clearing Cobalt Steel Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Carbide Drill Bits

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

Smooth-Finish Carbide Drill Bits

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits.

Carbide-Tipped Drill Bits

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

Drill Bits for Plastic

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

Drill Bits for Carbon Fiber, Fiberglass, and Graphite

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

Drill Bit Sets

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

Cobalt Steel Drill Bit Sets

Left-Hand Drill Bit Sets

Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws.
