About Drill Bits

Drill Bit Decimal Size Equivalents

Drill Bits

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

Chip-Clearing Drill Bits

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

Cobalt Steel Drill Bits

Short-Flute Cobalt Steel Drill Bits

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

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.

Quick-Change Carbide Drill Bits

Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.

Chip-Clearing Carbide Drill Bits

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

Carbide-Tipped Drill Bits

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

Drill Bits for Carbon Fiber, Fiberglass, and Graphite

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.

High-Speed Steel Left-Hand Drill Bits

Use for drilling in most metal.

Drill Bit Sets

Cobalt Steel Drill Bit Sets

Drill Bit Sets

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

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.

Quick-Change Carbide Drill Bit Sets

Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size.

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.
