Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications.

Quick-Change Carbide Drill Bits
Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in handheld drilling. All are jobbers’ length so they have the rigidity and length required for most applications.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Any-Diameter Drill Bits
Place a washer (not included) with an ID of the desired hole size over the bit and it acts as a stop to prevent the bit from drilling a larger hole.
Style A do not require a pilot hole.
Style B require a 1 29/64” pilot hole to start drilling.
