General Purpose Spiral-Point Taps
Available7 products
General purpose spiral-point taps are intended for threading a wide range of materials. The 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 create internal threads in through holes and are installed into a toolholder on a machine such as a lathe or CNC machine to operate.
Class of Fit
Metric Bright Finish General Purpose Spiral-Point Taps
These taps come in standard sizes expressed in millimeters. The bright finish on these taps provides a smooth, polished surface.

UN Fine Bright Finish General Purpose Spiral-Point Taps
UN fine (UNF) taps have more threads per inch than UN coarse (UNC) taps. Compared to UNC taps, UNF taps perform better in threading applications on thin-walled workpieces and hard materials. Fine threads provide more tensile strength and shear strength than coarse threads. The bright finish on these taps provides a smooth, polished surface.

Oversized Black-Oxide Finish General Purpose Spiral-Point Taps
Oversized taps have a slightly larger pitch diameter than standard taps. They are used to make threads in a hole before a coating or treatment is applied to the hole. Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter. 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.
