CNC short drill chuck for clockwise and anti-clockwise rotation

Design: DIN 69871, Form AD/B. 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 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.
