For mounting straight-shank tools with lateral flat according to DIN 1835 form B (Weldon)

For internal machining with boring bars

Surface roughness Ra < 0

Hardening depth 0

For mounting milling cutters with transverse or longitudinal groove

4021 x 20Cr13

In machining centres (machines with automatic tool changers)

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

Tensile strength in the core of min

Precision coolant supply: Improves chip evacuation and decreases the risk for chip jamming

which can cause high frictional forces on the thread flanks

All functional surfaces fine machined
