Tool clamping \ Tapping chucks and accessories
Synchronous tapping chuck steep taper according to ISO 7388-1 (ISO 7388-1)
For collet chucks type ER according to DIN 6499 ISO 15488

SK SK Form G 2,5
40 50 AD/AF IK 25000 rpm
Application: Execution:
For thread cutting on machine tools with synchro- ƒ Length compensation in compression and tension
nous spindles. With rigidly clamped screw taps, pitch 0.5 mm
errors cause high axial forces that can be compen-
sated for by synchronous tapping chucks through Advantage:
minimal length compensation under pressure and ƒ Pitch errors are compensated for under pressure
tension. ƒ Increased tool service life
