Extended-Length Drill Bits
Black-oxide drill bits produce less friction than uncoated drill bits.
For technical drawings and 3-D models, click on a part number.
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.

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.
