Carbide Drill Bits for Sheet Metal

Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing.
