Abstract: 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.

Abstract: The present disclosure concerns a saw tooth holder for a cutting disk of a rotary cutting machine. The saw tooth holder comprises a holder body having a tooth-receiving surface abuttable against a rear surface of a saw tooth of a tooth assembly and a trailing surface, opposed to the tooth-receiving surface, and defining a trailing oblique angle with respect to the tooth-receiving surface. The holder body has a fastener-receiving aperture extending therethrough between the tooth-receiving surface and the trailing surface and being accessible from the tooth-receiving surface and the trailing surface. The present disclosure also concerns a cutting disk comprising such a saw tooth holder, a saw tooth holder in combination with a tooth assembly, and a rotary cutting machine comprising such a cutting disk.

Abstract: A single-hand operable portable hand-held saw, including a handle portion with a motor. The motor is operably connected to one or more drive gears positioned on an interior side of a protective cover. One or more idle gears are positioned on an interior side of the protective cover. The idle gears and the drive gears are operatively coupled with and rotatably engaged with an annular saw blade. A throat opening in the protective cover is positioned adjacent a stop guide for stabilizing the saw against a material during cutting operations.

Abstract: Disclosed is a cutting tool mounted on a shaft rotating about an axis, including a body having first cutting inserts mounted with equal spacing at the outer periphery of the body, which first cutting inserts have a cutting edge extending across the width of the body at a predetermined peripheral radius from the axis; and second cutting inserts mounted with equal spacing adjacent the outer periphery on a first side surface of the body, which second cutting inserts have a cutting edge extending in an axial plane perpendicular to the axis. The cutting edge of each first insert extends up to a predetermined distance from the axial plane of the second inserts; and the cutting edge of each second insert preceding a first insert extends a predetermined radial distance outside the peripheral radius of the cutting edges of the first inserts. Also disclosed is a related apparatus.

Abstract: A circular saw blade includes a ceramic coating applied to opposing major surfaces in an outer margin of the circular saw blade where cutting teeth of the saw blade are arranged in spaced-apart relation and separated by blade tooth gullets. The ceramic coating inhibits abrupt increases in temperature of the outer margin during cutting operation to thereby inhibit the cutting teeth from deviating laterally. Methods of making saw blades include applying a ceramic coating to the outer margin using a plasma spray process or another coating process.

Abstract: A saw blade includes left and right set teeth which are set in a lateral direction, as viewed in a cuffing direction of cutting teeth. The left and right set teeth include dovetail shaped set teeth, each having a tooth tip formed into a dovetail shape gradually enlarged in the lateral direction, respectively; and a straight tooth, which is not set. The straight tooth includes a dovetail shaped straight tooth having a tooth tip formed into a dovetail shape gradually enlarged in the lateral direction. In the straight tooth, inclinations are formed on both of left and right ends at the tooth tip, which is formed into the dovetail shape gradually enlarged in the lateral direction.

Abstract: A circular saw blade includes a generally flat disk with a cutting periphery defined by a plurality of carbide teeth arranged in spaced relation around the perimeter of the disk and projecting radially outwardly from the disk. Each tooth of the cutting periphery includes a pair of spaced-apart primary side faces, a cutting face having a cutting edge with a top bevel angle within the range of at least 25 degrees to about 50 degrees, and at least two secondary side faces. Each secondary side face extends between the cutting face and a respective one of the pair of primary side faces and has a relief angle relative to the immediately adjoining primary side face. The circular saw blade of the present invention is ably suited to provide a smooth cutting finish without splintering of the top and bottom edges in connection with a wide variety of cuts, including crosscutting and ripcutting.

Abstract: An apparatus for cutting materials and more specifically an improved saw blade includes a plurality of variable teeth thereon. The variable tooth saw blade cuts faster and smoother while reducing harmonic vibrations. Specifically, the teeth on the saw blade are grouped into sections with differing circumferential widths and differing spacing between the sections.
