Tool clamping \ Tapping chucks and accessories
Synchronous tapping chuck, straight shank similar to DIN 1835 B+E (DIN 1835)
For collet chucks type ER according to DIN 6499 ISO 15488

G 2,5
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
