摘要： A saw blade having a blade body, a plurality of cutting teeth defining a cutting edge along an edge of the blade body, each tooth along the cutting edge defining a cutting tip. At least one tooth tip along the cutting edge includes a different material, such as, for example, high speed steel, carbide, diamond, and/or a tip coating, than at least one other tooth tip along the cutting edge. The plurality of teeth may be arranged in a repeating pattern or in no pattern along the cutting edge. A method of manufacturing the saw blade includes forming a cutting edge along an axial edge of a blade body, defined by a plurality of cutting teeth having respective tooth cutting tips, wherein at least one tooth tip along the cutting edge includes a different material than at least one other tooth tip along the cutting edge.

摘要： A metal cutting band saw blade has a plurality of cutting teeth defining a cutting direction, and a repeating tooth pattern of between 3 and 7 teeth. Each tooth defines a laterally-extending upper surface having a width and a height with respect to the back edge of the blade, and side surfaces extending laterally and downwardly on opposite sides of the upper surface relative to each other at acute angles relative to the upper surface. The teeth located rearwardly of the first tooth with respect to the cutting direction of the saw blade define progressively lower heights and progressively smaller acute angles of the side surfaces, and the widths of the upper surfaces of these teeth are greater than the width of the upper surface of the respective first tooth.

摘要： A sheet metal hole cutter (10) has a cap plate (12) defining a substantially circular peripheral groove (14) and an annular shelf (16) extending radially outwardly from the peripheral groove. An elongated band (18) forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge (22) received within the circular peripheral groove in an abutting relationship with an inner edge (24) of the groove. The band defines an axial depth (D2) of about 1/2 of an inch or less, and an outer diameter (F) within the range of about 9/16 of an inch through about 6 inches. A weld region (26) fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth (D1) of at least approximately 1/16 of an inch in order to prevent over-feeding of the hole cutter through a work piece. A plurality of teeth (30) are disposed along a cutting edge (28) of the band, and each tooth defines a cutting surface (44) extending between an outer edge (40) and an inner edge (42) of the tooth. Each cutting surface is oriented at an acute angle (A) relative to the plane of the cap plate such that the outer edge of the respective tooth is spaced further away from the cap plate than the inner edge to thereby preferentially cut the work piece with the outer edge and create a substantially burr-free hole in the work piece.
