For mounting straight-shank tools in collets

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

clamping depth l2 = max

In machining centres (machines with automatic tool changers)
