Alloy tool steel has good processing performance, good strength and toughness, so it is mainly used to manufacture complex thin cutting edges and impact resistant metal cutting tools, and also has higher processing performance. When tapping, first insert the head tap to make the tap centerline consistent with the drilling centerline. Both hands rotate evenly and apply a little pressure to feed the tap. No pressure is needed after feeding.Each time the tap is rotated, it reverses about 45 degrees to cut off the cutting, so as to avoid blocking. If the tap is difficult to rotate, do not increase the rotation force, otherwise the tap will break. Package Include : According to your choose. (Except some countries and APO/FPO).
