摘要： A cutting device (10) includes a sled (12) guided on a base (14) for reciprocating linear movement along a blade (20) that is supported on the base below the sled and includes an inclined working edge (28) projecting beyond the sled. The sled is manually movable while the blade is held stationary, so that a workpiece supported on the sled is conveyed against and along the working edge for cutting the workpiece. Mechanisms for adjusting the blade height, inclination angle, and bevel angle are also disclosed. Novel saw blades are also disclosed, and preferably include a blade extension extending from the working edge beyond the maximum travel of the sled. The blade extension may remain in the kerf at the end of a cutting stroke, preventing the blade from jamming against the workpiece upon a return stroke and may also provide an unobstructed means by which to gage blade angle relative to the sled.

摘要： An agricultural cutting blade has top and bottom surfaces and mounting apertures extending through top and bottom surfaces. A cutting edge support surface (e.g. that may be a flat, pointed or rounded) is formed on the cutting blade body with the cutting edge support extending along a side of the cutting blade body transversely between the top and bottom surfaces. A clad material deposited upon the cutting edge support such as by laser cladding process. The clad material can be built up, that is layered in partial or full overlapping relation to provide at least 2 and often more than 4 layers of clad material at one or more locations. A cutting edge provided by the clad material that may be a ground surface into a laser clad bead.

摘要： A reciprocating saw blade includes a body, and the body includes a connecting portion for connecting the blade to the saw, and a cutting edge. The cutting edge includes a plurality of teeth organized in an overall tooth set pattern. The overall tooth set pattern approximately corresponds to the stroke length of the reciprocating saw. By the overall tooth set pattern corresponding to the stroke length of the reciprocating saw, the cut time is decreased, the life of the blade is increased, the vibration is minimized and/or a smoother finishing cut is enabled.

摘要： A saw blade has a cutting edge including a plurality of teeth with a tip, a clearance surface on one side of the tip, a rake face on an opposite side of the tip relative to the clearance surface, a gullet, and a substantially flat or non-curvilinear projection between the rake face and the gullet projecting outwardly relative to the rake face. The projection is inclined at an acute angle relative to a plane extending between the tips of consecutive unset teeth, with an inner end adjacent to the rake face at least about 25/1000 inch below the tip and an outer end adjacent to the gullet. The distance between the inner and the outer ends in a direction substantially parallel to the plane extending between the tips of at least two teeth is less than about 65/1000 inch.

摘要： A band saw blade includes left and right set teeth which are set in right and left directions with respect to a running direction of the band saw blade, and a straight tooth which is not set. A ridge line at a tip of each of the set teeth and the straight tooth is formed into a convex curved line protruding most at a central portion in a thickness direction of the saw tooth. The ridge lines at the tips of the left and right set teeth and of the straight tooth are continuous with one another when viewed from the running direction of the band saw blade. A height difference between the ridge lines of the saw teeth is in a range of 0.02 mm to 0.1 mm. Meanwhile, a height difference between an inner corner portion of each of the left and right set teeth and the central portion in the thickness direction of the ridge line of the straight tooth is in a range of 0 mm to 0.03 mm.

摘要： A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis, an attachment portion configured to couple to the reciprocating saw, and a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face extending from the tip generally toward the longitudinal axis and defining a gullet, and a relief surface extending from the tip. The blade also includes a plunge point formed on the body for initiating a plunge cut. The plunge point includes a leading tooth and a second tooth. The leading tooth includes a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet. The second tooth is positioned in the leading gullet adjacent the leading tooth and is generally smaller than the leading tooth and each cutting tooth.
