Shrink chuck 4,5° with cooling channels SK 50 - 32 - 100Application: 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

Improves chip evacuation and decreases the risk for chip jamming

For d = 60 only with four fi xation screws according to DIN 912

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance3

For mounting screw-in cutters with thread

driving ring and feather key

- Maximum concentricity <0

With balanced clamping nut

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

LSCX = Clamping depth

For machining centres with synchronous spindle

longer tool life

Coolant pressure up to max
