54LK84 Extension Taps

Bulk orders will be discounted, please contact us.

The black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals. High-speed steel taps provide good wear resistance in general purpose tapping applications in a range of materials. Spiral-point taps have straight flutes with a spiral point that pushes chips in front of the tap as it moves into a hole and out the other side, eventually forcing the chips out of the hole. They are used for threading through holes.
