CNC short drill chuck for clockwise and counterclockwise rotation

Design: DIN 69871, form AD/B, from 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 to DIN 254. Hardened 58 ±2 HRC. Clamping using a hex spanner essentially increases clamping force in comparison to conventional chucks. At the same time, this secures the chuck against becoming loose during left-handed rotation or being quickly decelerated from higher speeds.

DIN 69871

Form AD/B

Taper angle: Tolerance AT3. Concentricity: max. 0.03 mm.

Application: To nest tools with cylindrical shank. Supplied: Short drill chuck with hex spanner.

CNC short drill chuck for clockwise and counterclockwise rotation

Design: Short model, guide elements of rigid design, hardened and ground wearing parts for long life. Compact design and high rigidity result in best machining results. High clamping forces are reached by the integrated worm gear at low effort, Holding torque > 75 Nm at 13 mm dia. Machining is safe thanks to automatic blocking of the worm gear even when in left-handed rotation and quickly dece- lerated spindle. Taper angle: Tolerance AT3. Taper surface roughness: Ra < 0.001 mm. Concentricity: < 0.03 mm. Max. permissible speed: 7000 min -1 . Balancing quality: pre-balanced up to 7000 min -1 at a residual imbalance of max. 40 gmm. Application: For drilling, countersinking, reaming, thread cutting and for simple finishing milling work. Can be used in machining
