Hydraulic expansion chuck SK 50-32-91 DIN 69871 AD/B in wooden boxApplication: For mounting straight shank tools acc. DIN 1835 form A+B+E and DIN 6535 form HA+HB+HE (larger than dia. 20 mm only with reduction sleeve). Note: l1 = max. clamping depth l2 = max. length adjustment range Delivery: With wrench All holders are made of forged steel Specific, low warpage hardened Surface hardened HRC 58~60 Hardening depth 0,8mm~0,9mm Taper angle tolerance < AT 3 according to DIN 2080 Surface roughness Ra < 0,4 m Tensile

For highest axial and radial loading

For machines with rigid tapping

200 x 63 x 18

The steel body is hardened and grinded all-round

For the inspection of machine tools according to ISO recommendation R230 or for testing the tool spindle

clamping depth = 58

prevents chip clogging

- Longer-lived than standard collets

Construction: Hardened steel

• runout accuracy: = 0

Stahlkörper allseitig geschliffen und gehärtet

A possible increase of axial force during the tapping process is reduced to a minimum
