Hand Taps


Product features
●Most suitable for stainless steels, sticky and tending to work-harden, as well as chrome steels and molybdenum steels, blind
hole use.
Cemented
Carbide Taps


●Reduction of cutting load on each cutting edge due to optimum design of thread portion.
●Decrease of cutting resistance and increase of tool life.
●Improvement of chip ejection and good thread finish.
●Increase of tool life due to the improvement of tap strength.
●Suitable for both rigid tapping machine and non-rigid tapping machine.
