Clamping
Systems
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.
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
DIN
69871
Form
AD/B
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
centres, turning, drilling and milling machines.
Supplied:
Short drill chuck with hex spanner.
