The greatest stability and rigidity of all known clamping system.

HOTBLOCK®: the new shrink fit chucks are high precision toolholders which ensure more precision having less coupling thanks to its special tight on the shank tool by thermal clamping. First, the collet tip is heated with the special shrink fit unit (see our article K.START.2), causing it to expand. The cutter shank is then inserted, and the collet is cooled to ambient temperature with the cooling machine (see our article K.FG500). This permits the operator to reach highest level of precision and stability, faster feed rate for high performance and longer tool life.

• Concentricity ≤ 0,003 mm (0.0001")
• Short and slim for better rigidity and improve chipping ejection
• High precision toolholders guaranteed by thermally induced shrink fit
• High rigidity and balance for heavy CNC working
• For clamping steel and solid carbide cutting tool
• Balanced to 24.000 RPM at G 2,5
• Right and left-hand rotation
• Cutting tool shank must have tolerance h6 with cylindrical shank (no flats)
