No dust tap series
No dust tap and cutting tap different points for tapping without clearance discharge as its characteristic, and the internal thread processing surface for pressure made surface appearance beautiful, smooth, material iron as continuous didn't cut off, thread strength about increased by 30% accuracy stability, because does not have the groove core diameter die endurance, torsion strength, tap life is long is not easy to break. Applicable ductility of big material. Iron, copper, aluminum, stainless steel plate and pipe class processing.
