Shrink chuck 4,5° HSK 63 - 12 - 160Application: For mounting tools with straight shanks. Note: Toolholders suitable for induction , contact and hot air shrink units. 3, 4, 5 with h4 tolerance and 6 32 with h6 tolerance For 3, 4 and 5 mm only solid carbide tool shanks must be used! 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

Clamping force preadjustable by graduation lines

Execution:

better chip evacuation

Clamping range h6 (nominal size only)

Only nominal size d can be clamped with sealing plug for internal cooling (applicable up to 21 bar) In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet

Through hole for internal cooling provided

Shortened processing times and reduction of production and unit costs

DIN 1835 form A+B+E and DIN 6535 form HB+HE

For mounting milling cutters with transversal groove

With internal cooling

which can cause high frictional forces on the thread flanks

The internal thread provided for the coolant tube in the PSC toolholder is plugged with the socket-head screw incorporated in the adapter
