Extended-Length Drill Bits
Black Oxide
Access hard-to-reach spots and drill deep holes.
Black-oxide drill bits produce less friction than uncoated drill bits.

Extended-Length Carbide-Tipped Drill Bits
Access hard-to-reach spots and drill deep holes. 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.
