  • Tool, tool body and cutting head
    Patent number: 8430609
    Abstract: A tool for rotary cutting machining includes a tool body and a replaceable cutting head detachably attachable to the tool body. The cutting head has a coupling portion which is receivable in a space between two axially projecting coupling legs of the tool body. Cylindrical internal gripping surfaces are arranged in said space and designed for engagement with corresponding cylindrical external gripping surfaces of the cutting head. The gripping surfaces of the cutting head and the gripping surfaces of the tool body are dimensioned so as to prevent, by engagement with each other, the cutting head from being displaced in axial direction away from the tool body when the cutting head is attached to the tool body. A tool body and a cutting head included in such a tool are also disclosed.

  • METHOD FOR PRODUCING CEMENTED CARBIDE PRODUCTS
    Publication number: 20130064708
    Abstract: A method for injection molding or extrusion of cemented carbide or cermet parts uses a binder system, including 20-70 wt-% olefinic polymer, 30-80 wt-% wax. The olefinic polymer is a co-polymer of polyethylene and poly(alpha-olefin). By using such a binder system, a tougher material behavior of the green body and a lower temperature during the injection molding or extrusion is achieved.
