The HSK-A63 collet chuck for ER32 collets delivers 3 µm concentricity and is balanced to G2.5 at 25,000 RPM. Designed for flexible CNC machining, it provides reliable clamping force and excellent concentricity across milling, drilling and general machining operations.
ER collet chucks provide a versatile and cost‑effective tool holding solution for CNC machining, offering excellent concentricity, strong clamping force and reliable performance across a wide range of applications. Compatible with ER collets manufactured to DIN 6499 / ISO 15488, they ensure stable tool clamping, reduced vibration and improved surface finish. Their robust design makes them ideal for workshops requiring flexibility without compromising precision or repeatability.
Features include:
The ThermoGrip® HSK-A63 shrink fit chuck for 32mm tools with 200mm gauge length is balanced to G2.5 at 25.000 RPM. This precision tool holder provides high clamping forces and excellent concentricity for demanding CNC machining applications.
ThermoGrip® cool jet shrink fit chucks provide optimised coolant supply through closable side channels, delivering targeted cooling directly to the cutting edge during CNC machining. This improves chip evacuation, stabilises cutting temperatures and extends tool life in demanding milling applications.
The ThermoGrip® HSK-A63 slim shrink fit chuck for 6mm tools with 200mm gauge length is balanced to G2.5 at 25.000 RPM. This precision tool holder provides high clamping forces and excellent concentricity for demanding CNC machining applications.
The ThermoGrip® shrink fit system ensures secure and precise tool clamping through the perfect combination of shrink fit machine and tool holder. Induction shrinking technology provides exceptional concentricity, high rigidity and extremely strong clamping forces for reliable CNC machining. The result is improved surface quality, longer tool life and higher cutting performance at increased feed rates and spindle speeds.
