Taper-Shank Drill Bits
Available532 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.

Bright Finish Spiral-Flute High-Speed Steel Taper-Shank Drill Bits
The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. 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.

Bright Finish Parabolic-Flute High-Speed Steel Taper-Shank Drill Bits
Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the workpiece. The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. 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.

Bright Finish Spiral-Flute Vanadium High-Speed Steel Taper-Shank Drill Bits
The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. Vanadium high-speed steel drill bits are made from high-speed steel, carbon, vanadium carbide, and other alloys. They provide more abrasion resistance and wear resistance than standard high-speed steel drill bits. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
