摘要： A reciprocating saw blade includes a body formed from a piece of coil stock. The body has a shank end configured to secure the blade with a reciprocating saw, a plunging end configured to enter a workpiece, and a cutting edge and opposite back edge extending between the shank end and the plunging end. The cutting edge has a plurality of teeth arranged in a pattern that includes left and right set teeth. A plurality of gullets is disposed between adjacent teeth. Each of the teeth and the gullets has substantially the same size, except that the first and third consecutive teeth immediately adjacent the plunging end have been flattened to be unset, and at least a portion of the second consecutive tooth has been removed to form an enlarged gullet between the first and third teeth.

摘要： A reciprocating saw blade comprises an elongated substantially flat body having a tang end and a distal tip end, a back edge and a spaced apart cutting edge. The cutting edge is formed of first and second pluralities of alternately and oppositely facing slicing teeth which define gullets formed therebetween. The first plurality of the slicing teeth extends from the one end and merges into the second plurality of the slicing teeth which extends to the other end. Each slicing tooth includes a slicing face facing one end, a planing face facing the other end, and a tip including an uppermost planar surface. The tips of the second plurality of teeth are substantially tangent to a first tooth tip tangent line. Each tip surface of the second plurality of teeth lies at a greater angle to the first tip tangent line than the tip surface of the first plurality of teeth. A method of making a reciprocating saw blade in accordance with the present invention is also disclosed.

摘要： A high speed hand tool includes a saw disc having less than ten teeth, preferably four. Each tooth has a radial flank, which preferably inclines forward in the cutting direction, and a tangential flank, which has a small clearance angle. The teeth may have a greater thickness than the disc itself which thickness, in that case, diminishes in a direction opposite to the direction of rotation. Alternatively, the teeth may be offset alternately to the right and the left. The invention also comprises an adjustable protective device which enables setting the depth of a perpendicular saw cut.
摘要翻译：高速手动工具包括具有少于10个齿的锯片，优选地为四个。每个齿具有径向侧翼，其优选地沿切割方向向前倾斜，并且具有小的间隙角的切向侧面。齿可以具有比盘本身更大的厚度，在这种情况下，该厚度在与旋转方向相反的方向上减小。或者，齿可以向右和向左交替地偏移。本发明还包括可调整的保护装置，其能够设定垂直锯切深度。

摘要： Sawblades for cutting materials containing abrasive grains or fibers with a power saw utilizing two reciprocating sawblades in contact with each other guided by a groove in a guidebar, all teeth on one blade pointing forwards and all teeth on the other blade pointing backwards. The teeth are located with unequal distances chosen so that two teeth on the first blade will not simultaneously be opposite two teeth on the other blade with the same distance as the teeth on the first blade.

摘要： A saw blade assembly comprises a laminated structure of three side-by-side parallel strips, one two or all of which may have spaced teeth formed along one edge. Where only one strip has teeth, it is sandwiched between the two other strips and the teeth are of triangular shape when seen in plan and are bevelled on both edges to produce pointed tooth tips. Where two strips have teeth, the strips are arranged one on each side of a center strip. Again, the teeth are of triangular shape when seen in side elevation and are contoured to form pointed tips. The roots of the teeth on one strip are spaced laterally from the roots of the teeth on the other strip because of the presence of the center strip. In another form, each strip has teeth along one edge, the assembly thereby providing three parallel, side-by-side rows of teeth. The teeth are of triangular shape when seen in side elevation and are contoured to form pointed tips.

摘要： A circular saw blade (20) includes a circular body (22) with a plurality of equally spaced teeth (32) and a corresponding plurality of gullets (34) formed integrally with and about the periphery of the body. Each alternate tooth (32) of a first set of alternating teeth has mounted thereon a carbide tip (36) with a cutting point (60) on the right side of the blade (20). Each of the remaining teeth (32) form a second set of alternating teeth and has mounted thereon a carbide tip (38) with a cutting point 72 on the left side of the blade (20). Each of the carbide tips (36) and (38) is formed with a converse front face (42), top bevel angle, side clearance angles and a front bevel angle.

摘要： A circular saw blade has block-like tooth tip inserts of hard metal, secured at circumferentially spaced intervals to the peripheral portion of a disc-like blade body having opposite flat side surfaces. The gullet in front of each insert, conventionally present in such a blade, is spanned in the circumferential direction, at least to a substantial extent, by a fixed thin wall, which can comprise a reduced thickness portion of the blade body, so that each gullet is thus defined by a sidewardly and radially outwardly opening cavity in a side surface of the blade, and the blade has a near-circular periphery. At the circumferentially rearward and radially inward portions of each cavity its edges are substantially bevelled to facilitate flow of cuttings out of the cavity.
摘要翻译：环形锯片具有硬质金属的块状齿尖插入物，其周向间隔地固定到具有相对平坦侧表面的圆盘状刀片体的周边部分。通常存在于这种叶片中的每个插入件前面的齿槽至少在一个固定的薄壁上至少在一个大的程度上沿着圆周方向跨越，该固定的薄壁可以包括叶片本体的厚度减小的部分，因此，齿形物由叶片的侧表面中的侧向和径向向外的开口腔限定，并且叶片具有近圆形的周边。在每个空腔的周向后部和径向向内的部分，其边缘基本上是倾斜的，以便于将切屑流出空腔。

摘要： A saw tooth intended primarily for sawing wood, particularly in one direction of movement, and having a tip which is given an increased thickness in relation to the remainder of the tooth by upsetting or some other method, and bevelled surfaces so arranged that they form one or more oblique cutting edges presenting a clearance angle. The cutting edge or each of the cutting edges is formed by the intersecting line between a bevelled surface on an upper surface on the tooth and an under surface on said tooth. The bevel angle is at least 27* and at most 60*.
