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.

Short-Flute Extended-Length Carbide-Tipped Drill Bits

The short flutes provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots. 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. A split point keeps the bit centered without a pilot hole.
