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.

Extended-Length Cobalt Steel Drill Bits
Access hard-to-reach spots and drill deep holes. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. The split point keeps the bit centered without a pilot hole.

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.
