Yamawa Spiral Tap (for metric threads) for medium carbon steel

Suitable for applications where the threads cut by standard precision taps are small.
Suitable for cases where a larger than normal size internal thread is required before plating, etc.
The twisted groove discharges small, curled chips to the rear, preventing chip clogging and making it ideal for blind hole machining.
Its sharpness makes it ideal for threading sticky work materials and plastics.
The tap is easy to bite.
Intermittent cutting of pilot holes with key grooves is also possible.
The blade strength is inferior to that of HT, so the HT shape is more suitable for high hardness materials.
For machining blind holes.
Work material: medium carbon steel.
