Product Details

These bits have a straw/bronze finish that improves their wear resistance. Cobalt drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

Taper-shank drill bits are directly inserted into the spindle, driving sleeve, or socket of a machine such as a drill press or lathe. This saves time when installing and changing out bits on the machine compared to other styles of drill bits. Taper-shank drill bits are self-locking, which means the friction between the bits and the tool holder keeps the bits in place, even in high-torque applications. These bits should not be used in a collet or chuck.
