Extended-Length Drill Bits
Black Oxide
Titanium Nitride (TiN) Coated
Access hard-to-reach spots and drill deep holes.
Black-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 black-oxide drill bits.

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 fiberglass, carbon fiber, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
