439C85 Taper-Length Drill Bit Sets

Bulk orders will be discounted, please contact us.

The high-speed steel taper-length drill bits in these sets provide good flexibility and absorb some shock and vibration, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. The bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide drill bits should only be used for drilling ferrous metals. These sets include drill bits in a range of sizes.
