Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size. Harder than high-speed steel, cobalt steel, and carbide-tipped bits, these maintain their sharp edges longer. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.
