GBP 57 G 2.5 ≤3µm ISO DIN DIN Form 25000 HSC HPC 12164-1 69882-4 69893 A min-1 Performance milling chuck − ISO 12164 (DIN 69893-1) ■ With RFID/Balluffchip bore. ■ All shanks hard turned. A ■ Supplied with 4 table cooling channel bores. Advantage: ■ No risk of the cutter being pulled out, not even a tug. D D2 D1 ■ Optimised external contour − vibration-damping behaviour. ■ Pleasant handling thanks to the differential thread. ■ Breakage of the milling cutter shank is improbable. ■ Precision version. 30 4450 Application: For clamping tools with side drive flats to DIN 1835 Form B and DIN 6535 Form HB. Best suited for TPC milling or high feed rate applications. No risk of the cutter being pulled out, more precise radial run-out, process reliability!

All shanks are hard turned for smooth running. Including RFID/ HiRunER Standard ER chuck Balluffchip bore, high-performance clamping nut up to 25000 rpm. ■ Collet is fully seated in ■ Collet is not inserted Advantage: ■ Excellent concentricity in the system (chuck + collet + clamping nut), the chuck 100 % in the chuck. 3 µm radial run-out with a 2 µm collet, 6 µm radial run-out with a 5 µm collet. ■ Higher clamping forces! ■ Improved radial run-out! ■ Extremely strong holding force (up to factor 2 better than the standard ER chuck). ■ Vibration reduction effect due to 2-part clamping nut (one part for mini version). Application: For clamping tools with plain shank in collets to DIN 6499 - Form A and B. Supplied with: Precision clamping nut.
