Brand: YAMAWA spiral wire attack
Spiral wire tapping N-SP, HC-SP:
Spiral wire attack
The difference between the spiral wire tapping and the ordinary hand wire tapping is that the groove of the ordinary hand wire attack is linear, while the spiral wire attack is spiral. When the screw thread is used to attack the tooth, the iron filings can be easily discharged from the hole by the spiral rotation of the spiral groove, so as to avoid the residual iron or the blockage in the groove, and cause the broken edge of the wire tapping and breaking, so that the life of the wire tapping can be increased and the thread with the highest precision can be cut out. Spiral wire tapping is suitable for cutting high toughness materials, but not suitable for fine chips such as cast iron.
HC-SP has a spiral groove of 35 degrees, which is most suitable for tapping holes with sticky material and plastic material, such as medium carbon steel and high carbon steel.
