An inline edge-sealing apparatus and method for sealing the kerf surfaces of cut cellular PVC board includes a rotary saw with either a tandem sealing disc or with an integral elevated sealing surface that is dimensioned to provide precise interference with kerf surfaces for friction and heat to melt and seal the surfaces in an aesthetically desirable manner. A kerf splitter, such as a kerf splitting pin, rod or riving knife, may be provided following a saw blade with integral kerf-engaging surface to avoid disruption of the sealed surface when cut boards exit the saw blade teeth.

A saw blade holder for a saw blade having a central aperture. The saw blade holder includes a base, a blade mount extending from the base, and a retaining member removably coupled to the blade mount for retaining the saw blade on the blade mount. The blade mount is configured to be received in the central aperture of the circular saw blade. At least a portion of the blade mount is flexible. The retaining member is removable from the blade mount and reusable.

A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

A cutting blade for a clearing saw includes a plurality of teeth, with at least some of the teeth having a leading edge, a trailing edge, and a point in between the leading and trailing edges. The trailing edge can be hardened to a depth in the range 0.02-1.5 mm, and the leading edge may be left unhardened to provide a cutting blade with increased durability and efficiency, that can still be filed manually to remain sharp.

A tool system includes at least one machining tool, in particular at least one oscillating machining tool, and at least one additional machining tool, in particular at least one additional oscillating machining tool. The at least one machining tool and the at least one additional machining tool are of the same type, and the at least one machining tool and the at least one additional machining tool differ from each other in at least one cutting blade characteristic, in particular cutting edge characteristic.

A tip saw has disk-shaped and comprises cutting blade pieces, support pieces, and a base metal. The cutting blade pieces are disposed at blade edges of the tip saw. The support pieces are disposed between adjoining two of the cutting blade pieces. The cutting blade pieces and the support pieces are configured to be thicker than a thickness D1 of the base metal of the tip saw (D2>D1). The support pieces have a thickness equal to or nearly equal to the thickness D2 of the cutting blade pieces (D3=D2 or D3≈D2). Consequently, the width of a cut groove Pc formed on a work material by the cutting blade pieces can be maintained wider than the thickness D1 of the base metal of the tip saw by the support pieces without increasing the number of the cutting blade pieces of the tip saw.

A ring saw blade includes a flat annular support which has a side face and an outer circumference. One or more cutting elements are disposed along the outer circumference. An annular groove is recessed into the side face and has a radially inner flank and a radially outer flank. The radially inner flank is conical and a first cone describing the radially inner flank has a half opening angle of between 10 degrees and 30 degrees.

In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.

A circular saw blade comprising: a rigid central disk that is provided with a central pass-through hole adapted to be engaged by the machine-tool spindle; and a series of teeth that jut out from the periphery of the rigid central disk in a substantially radial direction, are suitably spaced along the periphery of the rigid central disk and have, on their front edge, a cutting insert; at least one of said teeth being provided with a plate-like protruding ridge or appendage that projects from the back of the tooth, towards the cutting insert of the following tooth, and is tapered towards its distal end; said protruding appendage and the front edge of the following tooth being shaped so as to form a substantially circular-shaped gullet in front of the following tooth.

A unique design is provided that increases the strength and extends the life of an asphalt saw blade. The asphalt saw blade may include a main body, outer plates and cutter assemblies that are secured to the main body and outer plates. The cutter assemblies can include a front cutter component and a rear cutter component that interlock. The front cutter component may include cutting elements and a plate that reinforces the cutting elements while also shielding the front cutter component's main body from wear. The rear cutter component may also include cutting elements.
