About Drill Bits

Drill Bit Sets

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

Chip-Clearing Drill Bit Sets

Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.

Cobalt Steel Drill Bit Sets

Short-Flute Cobalt Steel Drill Bit Sets

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.

Carbide Drill Bit Sets

For the highest accuracy and longest tool life, these solid-carbide bits are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits.

Carbide-Tipped Drill Bit Sets

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.

High-Speed Steel 1/2" Diameter
Reduced-Shank Drill Bit Sets

Use these bits for general purpose drilling in most material.

3/8" Diameter Reduced-Shank Drill Bit Sets

1/4" Diameter Reduced-Shank Drill Bit Sets

Drill Bit Sets for Plastic

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

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.
