Chip-Clearing Cobalt Steel Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

Smooth-Finish Carbide Drill Bits

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits. 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 hand-held drilling. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

Hex-Shank Drill Bits with Guide for Countersunk Holes


The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit. Guides are spring loaded; drilling pressure compresses the guide body and extends the drill bit into the workpiece. Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank. Also known as Vix bits.
