SPIRAL POINT DIN376 HSS-COBALT TAP M20X2.5 BLACK RING

Spiral Point/Gun Nose. ISO Metric. HSS-E Bright Finish. For through holes. Taper lead to DIN form B. Tapping tolerance to 6H. Spiral point 'Eminent' chamfer form B through holes all round IS0 2 (6H). The tool geometry (with up to 138 parameters) has been developed and optimised during long-term tests in co operation with users for the different sections of structural steel, aluminum casting, machining steel, VA steels, heat-resistant steels and tool steels. Selected hard coatings increase the range of applications. The objective of developing Swiss+Tech's 'Black Ring' Taps was the realisation of narrower tolerances and more efficient cutting times. for the thread production.
