With drivers

For mounting tools with straight shanks

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

better process security and productivity
