Drill Bits for Precise Holes in Wood
Black-Oxide Steel
Uncoated High-Speed Steel
Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. The center guide point prevents the bit from wandering. Also known as brad-point bits.
High-speed steel drill bits are stronger and more wear resistant than steel drill bits.

Drill Bits for Carbon Fiber, Fiberglass, and Graphite
Uncoated Brad Point
These jobbers'-length bits have the rigidity and length required for most applications. They are designed to make clean holes in abrasive material. Their point keeps the bit centered without a pilot hole.
Uncoated drill bits have three drill points that make clean holes in fiber-reinforced composites without fraying or delaminating the material.

Hex-Shank Drill Bits
Black Oxide
Titanium Nitride (TiN) Coated
Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. A split point keeps the bit centered without a pilot hole.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than black-oxide drill bits.

Hex-Shank Drill Bits with Guide for Countersunk Holes
The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit. Guides are spring loaded; drilling pressure compresses the guide body and extends the drill bit into the workpiece. Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank. Also known as Vix bits.
