Design: DIN 2080, Form A, made of alloy case-hardened steel, with a core tensile strength of approx. 950 N/mm 2 and a hardness depth of min. 0.5 mm. Taper according to DIN 254. Clamping using a hex spanner considerably increases clamping force in comparison to conventional chucks. At the same time, this secures the chuck against becoming loose during anti-clockwise rotation or being quickly decelerated from higher speeds. Taper angle: AT3. Concentricity: ≤ 0,03 mm. Hardened 58 ±2 HRC. CNC chuck for clockwise and anti-clockwise rotation

CNC short drill chuck for clockwise and anti-clockwise rotation

Design: Short design, guide elements of rigid design, hardened and ground wear parts ensure high concentricity and long life. Compact design and high rigidity lead to the best machining results. High clamping forces are reached by the integrated worm gear at low effort, Holding torque > 75 Nm at 13 mm diameter. Machining is safe thanks to automatic blocking of the worm gear even when running anti-clockwise and quickly decelerated spindle. Taper angle: Tolerance AT3. Taper surface roughness: Ra < 0.001 mm. Balancing quality: pre-balanced up to 7000 min -1 at a residual
