摘要： A reciprocating saw blade is provided including a blade cutting edge including a plurality of teeth and a plurality of gullets. At least a portion of the plurality of teeth each includes a rake face, a relief face, a tooth cutting edge, and at least one non-cutting tooth edge extending on a first side face transverse to the rake face and the relief face, and a second side face opposite the first side face and transverse to the rake face and the relief face, a first relief-side edge at a junction between the first side face and the relief face, and a second relief-side edge at a junction between the second side face and the relief face. At least one of the first and second relief-side edges includes a modified portion extending rearward from the rake face.

摘要： A saw blade includes a body and a plurality of cutting teeth formed on the body. Each cutting tooth includes a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. Each gullet forms an undercut portion between the body and the projection of each cutting tooth.

摘要： A cutting blade with multiple body inserts, each comprising a load-sharing member and a flexible perimeter joint. These inserts reduce the magnitude of frictional forces acting on the blade's body. The load-sharing member, in particular, acts as a point contact between the material being cut, such as bone, and the cutting blade. As such, the frictional forces exerted act only on the load-sharing member as opposed to the entire body. By limiting the real contact area, the magnitude of friction generated during operation is reduced. Additionally, the load-sharing members create a thermally insulating space between the body and the material being cut. The functionality of these body inserts, however, relies on the flexible perimeter joint. The flexible perimeter joint isolates the effects of frictional forces to the load-sharing member by preventing direct contact between the load-sharing member and the surrounding body.

摘要： A saw blade includes saw teeth arranged along a toothed side. The saw teeth have a pitch that increases from a clamped end of the saw blade to a saw blade tip. The saw teeth include a tooth support and a hard metal tooth joined to the tooth support. The saw teeth have a plurality of tooth supports having the same shape. Larger tooth spaces are provided for the increasing pitch between tooth supports having an identical shape.

摘要： A saw blade has a plurality of teeth with each tooth formed by a beveled leading face, a beveled trailing face and a chamfered surface located on the trailing face of each tooth. The trailing and leading faces are beveled in opposite directions in alternate order throughout the saw blade prior to the forming of the chamfered surface. The beveled leading face of each tooth intersects the chamfered surface on the trailing face of each tooth to form a curved cutting edge having a negative rake angle. The beveled faces are manufactured by first forming a plurality of rough-formed gullets. The rough-formed gullets are then finished-formed into beveled gullets by a cold-forming operation prior to the grinding of the chamfered surface to form the curved cutting face of the tooth.

摘要： A sawblade includes a plurality of wave-shaped teeth formed on a continuous base section of the sawblade. Each of the teeth has a paired tooth base with a tooth base upper face and a hard metal blade arranged thereon. Each tooth base adjoins the hard metal blade arranged thereon in a flush manner on both sides along a longitudinal axis of the base section, and each hard metal blade and each tooth base upper face has two bevels and/or convexly rounded areas extending substantially along the longitudinal axis of the base section, wherein the teeth are designed to be set and/or unset.
