Extended-Length Drill Bits

Black Oxide

Uncoated

Access hard-to-reach spots and drill deep holes.

Black-oxide drill bits produce less friction than uncoated drill bits.

Chip-Clearing Drill Bits

Uncoated Parabolic Spiral Flute

Parabolic spiral flute drill bits have wider flutes for more efficient chip evacuation than spiral-flute bits.

Drill bits with a split point keep centered without a pilot hole.

Carbide-Tipped Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they 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.
