Heavy-duty Chuck, BT 40, Clamping Diameter: 32mm

Low friction due to needle bearings. Protected with anti-corrosion coating. Dust-tight and watertight. Very high clamping force prolongs tool life and improves surface quality. Flexible clamping range by means of collets. Clamping force up to 1000 Nm. Callout: Internal axial recesses effectively prevent the tool slipping. High radial stiffness due to repeatable clamping accuracy against a flat face, which prevents misalignment and ensures a high accuracy of machining, coupled with long tool life. T-slots take up the oil and grease, so that reliable torque transmission is achieved. Absolutely smooth running of the clamping nut. Application: For clamping tools with plain shanks.
