  • Patent number: 9604290
    Abstract: A milling tool for working non-metal materials, in particular wood, engineered wood, and plastic, includes a carrier body, a plurality of cutting elements, which can be inserted into said body on the periphery in a corresponding number of openings extending in the radial direction and can be screwed to the carrier body by way of a bore and which have a plate-shaped and in the cross-section a substantially triangular-shaped design and on a side edge are provided with a blade. The cutting element includes: the region located opposite of the blade is rounded, a groove extending substantially at a right angle to the blade is provided in the bottom, the bore divides the groove preferably into two regions.
    Type: Grant

  • Patent number: 8074688
    Abstract: A machine tool, in particular a wood-working machine, with a tool for chip removal rotating in direction of rotation D and a suction hood covering the tool with a partially opened circumferential wall that has a radial spacing A from the tool and that has a suction nozzle for suctioning off chips. In the machine tool rotating air vortices directed in the opposite direction based on the direction of rotation D of the tool can be generated in the suction hood in the area of the suction nozzle during the chip removal.

  • Publication number: 20030000363
    Abstract: In a sawing tool for a hand circular power saw with two coaxial saw blades (11, 12), which can be driven to counter-rotate in relation to each other, which each have an outer set of teeth (13, 14) that represents a main cutter, in order to improve the cutting result even with continuing wear on the cutting edge and in order to reduce damage to the teeth (13, 14) when the saw blades (11, 12) are imperfectly balanced, a trimmer (10) is disposed between the two saw blades (11, 12), which serves to cut away a piece of material possibly remaining in the kerf between the saw blades (11, 12) and which is non-rotatably attached to one of the saw blades (11, 12) and shares an axial overlap with the main cutters (FIG. 3).
