Carbide Drill Bits for Stainless Steel and Nickel
Harder, stronger, and more wear resistant than cobalt 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. All are titanium nitride (TiN) coated for longer life and higher drilling speeds. They are short length, also known as screw machine and stub length, which provides maximum rigidity for drilling straighter holes than standard-length drill bits. The split point keeps the bit centered without a pilot hole.
