摘要： An arbor for a guided circular saw has three symmetrical lobes. The lobes have end regions with profiles which follow an arc centered on an axis of rotation of the arbor. The lobes have driving regions with profiles which follow the arc of a circle centered in an opposing lobe. A saw for use with the arbor has an eye with a shape which follows the contour of the arbor. The saw is capable of floating axially along the arbor. The saw and arbor can be used to advantage in sawing machines such as edgers. The arbor provides a much larger saw contact area than do prior art arbors. In one embodiment of the invention the saw is mounted between a pair of spaced apart collars on the arbor. The collars guide the saw but are not tightly clamped to the saw.

摘要： A side cutting edge of a tip 20 fixed to the outer circumference of a circular saw blade body 11 has a inflexion point K at a portion at which the tip projects laterally to the greatest distance. An outer-circumferential-side portion of the side cutting edge has a negative radial clearance angle of not less than −1° but less than 0° at the inflexion point, and an inner-circumferential-side portion of the side cutting edge has a positive radial clearance angle of greater than 0° but less than −1° at the inflexion point. By virtue of this configuration, a cut surface having a better surface roughness as compared to that obtained conventionally can be obtained in cutting of a soft material such as wood by use of a circular saw.

摘要： A cutting tool for separating and formatting of sheet materials has a rotationally driven support body having cutting teeth arranged about a circumference of the support body. The cutting teeth have a tooth profile with a radially outwardly positioned front-cutting area with a separating cutting edge and a formatting area with main cutting edges determining the cutting width of the cutting tool. The tooth profile further has a transition area located radially between the front-cutting area and the formatting area. The main cutting edges in the formatting area are arranged radially separately from the separating cutting edges of the front-cutting area by the transition area, wherein the transition area has transition cutting edges adjoining the cutting edges and angled relative to the separating cutting edges toward a radial center axis of the cutting tool. The front-cutting area is symmetrical relative to the radial center axis of the cutting tool.
