Fluteless Machine Taps with Oil Groove, DIN 371, HSS-E, M 8 x 1,25 

for chipless production of internal threads Advantages: - longer endurance as cutting taps - higher possible cutting speed - steady exactness of dimension and profile - high stability of the forming threads - high security against fracture - no removal of swarf, no jaming of swarf Application: - with TiN-coating for steel up to approx. 900 N/mm² - unalloyed and low alloyed steel - Structural Steel - heat resistant steel - stainless steel - for long-chipping nonferrous Metal (Cooper, Brass, Bronze, Alu) - Zinc alloys - for through and blind holes Oil Groove: - for optimueffect of lubrication of thread depth over 1,5 x D - Use graphite lubrication/oil or add another suitable lubricant. Thread type: metric ISO-thread DIN 13 Norm: DIN 371 Material: HSS-E
