General Purpose Spiral-Point Taps
Available135 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.
Thread Length
UN Coarse Bright Finish General Purpose Spiral-Point Taps
UN coarse (UNC) taps have fewer threads per inch than UN fine (UNF) taps. Compared to UNF taps, UNC taps perform better in threading applications on brittle materials and are less likely to cross thread. Coarse threads can also withstand more physical abuse than fine threads. The bright finish on these taps provides a smooth, polished surface.

TiN-Coated General Purpose Spiral-Point Taps
The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish.
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.
Black-Oxide Finish General Purpose Spiral-Point Taps
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.
Oversized Bright 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 bright finish on these taps provides a smooth, polished surface.
TiCN-Coated General Purpose Spiral-Point Taps
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating.
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.
