Shrink chuck 4,5° SK 40 - 20 - 120

Shrink chuck 4,5° SK 40 - 20 - 120Application: 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 tolerance6 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

Designed to provide precise angular measurements

Angle reading = 10 arcmin

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

set contains following adaptors:

- Calibration of the angular position of spindles of milling-turning centres

no adhesion occurs and the tool

The tapered tool holder is thus optimally

For sealing tools with internal cooling in collet chucks

With balanced clamping nut All holders are made of forged steel

For clamping tools with Morse taper shank and thread according to DIN 228-1 form A

For sealing tools with internal cooling

for clamping holders with coolant channels directly to the cutting edge
