Hydraulic expansion chuck SK SK 40-25-117 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: Without 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 mounting straight-shank tools in collets

In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet

low warpage hardened

With high precision coolant you get improved

For the transfer of a defined torque

Effective from low to high coolant pressures

154 x 54 x 17

Carbide tipped scriber with clamp

For mounting straight-shank tools in collet chucks DIN 6499

Minimal length compensation on compression and expansion balances very small pitch differences between synchro spindle and tap

Hinged mounting device for toolholders

All functional surfaces fine machined
