Shrink chuck 4,5° BT 40 - 10 - 90Application: 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

With 8mm stem diameter

For the storage of tapping quick change adaptors

In the tailstock of the lathe so that no friction between the workpiece and the tip occurs

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance9

you have achieved the reference value 50 mm

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

Without the illustrated cutting tools

Automatic On/Off to maximize battery life

For holding tapers according to DIN 69871

Ground internally and externally

wrench and collets

Longer durability of inserts
