คุณลักษณะ

• Suitable for tapping machine for street holes.
• Used for threading through holes, ideal for work materials such as hard steel and non-ferrous metals with stickiness.
• Since the core thickness of the tap is large, the twist strength is the strongest and there is almost no breakage.
• The chips are completely pushed forward in a spiral.
• Since the cutting blade is spiral shaped and has a large angle, it is shir-cut, so the cutting torque is extremely light (about 1/2 of the hand tap), and in order to increase the abrasion resistance, the screw part is homo-treated, and the durability is unrivaled by other companies.
• Regular thread.
