Shrink chuck 4,5° SK 40 - 25 - 160

Shrink chuck 4,5° SK 40 - 25 - 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 tolerance1 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

For mounting straight-shank tools in collet chucks DIN 6391

Without wrench

With built-in tightening bolt

DIN 1835 form A+B+E and DIN 6535 form HA+HB+HE (larger than dia

- Higher repeat-accuracy

DIN 1835 form A+B+E and DIN 6535 form HB+HE (larger than Ø 20 mm only with reduction sleeve)

For machining centres with synchronous spindle

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