Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications.
Black-oxide and black-and-gold-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.
Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.
Drill bits with a split point keep centered without a pilot hole.

Short-Flute Extended-Length Carbide-Tipped Drill Bits
The short flutes provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots. More wear resistant than cobalt steel and high-speed steel, these 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. A split point keeps the bit centered without a pilot hole.

Drill Bits for Wood Screws
These bits are cut to match a wood screw’s thread and diameter, resulting in a perfect fit for a screw. They produce clean edges when cutting soft and hard wood.

Round-Shank Drill Reamers
Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these drill reamers are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as carbon fiber, fiberglass, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
