Spiral Point
Premium High Speed Steel Plug Style
offers exceptional value for high volume production tapping in long-chipping steels and stainless steels up to 35 Rc hardness. Steam Oxide Over Nitride resists chip welding, increases lubricity and helps to retain cutting fluid. TiN Coating increases hardness and lubricity for improved thread quality, higher speeds and longer tool life. Primarily designed for tapping through holes. The spiral point forces the chips ahead of the tap. 3
