DIN 69871 tool holder

SKfor machininghigh-speed

Standardised to DIN 69871 with retention knob Torque transmission by means of the friction contact of the taper with low strain For larger torques and sudden loads, driving keys are primarily responsible for the transmission The driving keys are arranged asymmetrically on the spindle face for clear orientation for the tool Easy production Self-centring due to steep taper High speeds can expand the spindle cone and the resulting centrifugal force can cause axial distortion of the tool The centrifugal force distortion reduces the contact surfaces and therefore the frictional transmission of torques
