Abstract: A slitting tool for a circular saw machine has a tool carrier with a first and second tool flanges arranged coaxially and axially displaceable relative to one another. A slitting saw blade has first and second blade halves. Fasteners are provided for fastening the first blade half in a detachable manner to the first tool flange and for fastening the second blade half in a detachable manner to the second tool flange. The fasteners are distributed circumferentially about the tool carrier. An adjusting device is arranged within the tool carrier and connects the two tool flanges to one another. At least one fastener is arranged in a displaced position relative to other fasteners for balancing the slitting tool, wherein the displaced position is determined according to balancing criteria.

Abstract: Various clamping mechanisms are known for clamping shank-like tools such as drills, milling cutters and the like. The known clamping mechanisms often require long setting times involving long idle times when changing tools, particularly on machines with several spindles. The instant disclosure teaches a clamping mechanism allowing rapid tool change on the machine spindles and having good concentricity characteristics. A bayonet catch-like locking device is used for this purpose.
