1V691 Reduced-Shank Drill Bit Sets

Bulk orders will be discounted, please contact us.

The reduced-shank drill bits in these sets 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. These bits are made from high-speed steel. They provide more flexibility and absorb more shock and vibration than cobalt 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 sets contain multiple drill bits in a range of sizes.
