HIGH-PERFORMANCE MILLING CHUCKS HKS-SYSTEM The high-performance milling chucks are suitable for almost all applications. Especially in heavy roughing we guarantee unsurpassed high clamping forces and high process reliability. HKS DIN 69871 power chucks lead through the rigidity of the chuck, its concentricity and clamping even at 3 mm from nose lining to excellent surface finish and high tool life. All HKS chucks grant a maximum deviation of concentricity of 3 µm at 3 x D. Application: ISO 60 • heavy roughing • finish milling • hard milling • drilling, reaming • thread milling MAS 403 BT Concentricity: Max. deviation of concentricity 3 µm at 3 x D of the clamped tool.. Balancing: DIN 2080 Standard fine-balanced (G 6,3 15.000 min–1). Clamping shank: All available tool shanks with or without Weldon shank can be clamped directly or with an adaptor sleeve.
