Spacer
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.
Taper angle: Tolerance AT3.
Concentricity: < 0.03 mm.
Hardened 58 ±2 HRC.
Application:
To nest tools with cylindrical shank.
Scope of delivery:
Short drill chuck with hex spanner.
