Taper-Shank Drill Bits
Available287 products
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.

Black-Oxide Finish Spiral-Flute High-Speed Steel Taper-Shank Drill Bits
These drill bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

Straw/Bronze Finish Spiral-Flute Cobalt Taper-Shank Drill Bits
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.
