The present invention provides an apparatus and method for cutting a chamfer into the edge of a material while simultaneously making another cut in the material. The chamfer provides the cut material with reduced susceptibility to top surface edge swell.

A cutting or grinding tool includes a blade. The blade includes a disc-shaped base metal, cutting or grinding tips (edges) provided on a peak (outer circumferential edge) of the base metal, and a protruding coating on a side face of the base metal along the entire outer circumference of the base metal.

The present disclosure is directed towards an Improved Circular Saw Blade for simultaneous and combination cutting and chamfering a workpiece comprising a modified circular saw blade configured as a primary cutter to be mounted to one end of an arbor shaft rotatable on an axis. The modified circular saw blade comprises a plurality of substantially identical slots spaced circumferentially and extending radially inward towards the center. A modified chamfer tool is then configured as a secondary cutter to be aligned and mounted coaxially behind the primary cutter on the arbor shaft. The modified chamfer tool comprises angularly disposed peripheral chamfer blades mounted in the slots of the primary cutter so as to be displaceable transversely to the longitudinal axis of the modified circular saw blade. During manufacturing operations the peripheral chamfer blades of the secondary cutter are configured to follow the path of the primary cutter for simultaneously cutting and chamfering of the workpiece to a certain desired length and angle, respectively.

A saw blade (10) comprises a generally circular blade base body (100), and a plurality of teeth (101a, 101b), extending radially from the base body (100). The teeth (101a, 101b) are alternatingly set towards opposing axial (A) directions of the saw blade, such that each tooth presents a respective tooth plane, which is angled relative to a base body plane. The teeth (101a, 101b) present a respective first cutting edge (102a, 102b), extending along a radially distal edge portion (103) of the respective tooth, along a length of the tooth, as seen in a direction of rotation of the saw blade. The radially distal edge portion (103) presents a first bevel (104), providing a first bevel surface (105) which is non-perpendicular relative to the tooth plane. The radially distal edge portion (103) presents, at a radially outermost portion thereof, a hard portion (106) having greater hardness than the base body (100). The saw blade can be used in a brush cutter.

A saw tooth mountable to a circular saw disc and including a body defining rear and front ends. In operation, the front end leads the rear end as the saw disc turns. A cutting tip extends from the body and defines a cutting tip base adjacent to the body and an opposed cutting edge. The cutting tip base is rearwardly provided relative to the cutting edge. An elongated gullet extends along the cutting tip substantially adjacent to the cutting tip base and defines opposed gullet first and second ends and a gullet longitudinal axis therebetween. A gullet nadir line extends longitudinally between the gullet first and second ends and joins locations along the gullet that are closest to the rear end at all longitudinal positions along the gullet. The gullet nadir line is closer to the rear end at the gullet first end than at the gullet second end.

In various embodiments, a splitter profiler apparatus may include at least one profiler head and at least one circular saw mounted to a common arbor. The circular saw may be mounted to a saw arm, and the saw arm may be coupled with an actuator that is selectively operable to move the circular saw along the arbor. The circular saw may be used in a profiling position, in which the circular saw and profiler head are in close proximity, such that the profiler head and circular saw function collectively to form a sideboard edge with a sawn finish. The circular saw may also be used in a splitting position, in which the circular saw is at a distance from the profiler, to divide the sideboard into narrower sideboards before the sideboards are sawn from the primary workpiece. Corresponding methods and systems are also described herein.
