  • Patent number: 10646937
    Abstract: A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

    Abstract: A disc-shaped tool includes a plurality of virtual regions formed such that it is surrounded by two radius lines extending from a rotation center of a disc-shaped base metal and two concentric circles on the base metal disposed around the rotation center. A central angle formed by the two radius lines is equal to or less than 90°, and the number of the virtual regions is 4 to 24. The concentric circle located in a center of an interval of the two concentric circles forming the virtual region is in a range of 0.6 r to 0.8 r with respect to the rotation center of the base metal when a maximum gullet bottom radius of the base metal is r. An overlapping of the virtual regions continuously adjoining each other is in a range of 0° to 12°. A minimum neighborhood distance between the adjoining slits is equal to or more than 0.05 r. A ratio of a length of an arc of the central concentric circle in each virtual region with respect to the interval of the two concentric circles in the virtual region is 3 to 6.

  • Publication number: 20110030510
    Abstract: A method and device for producing band saw blades, particularly for the timber-processing industry. A blank band saw blade is produced from a metal band, such as a metal band that can be stored on a roll. Several metal bands are combined into a flush metal band packet which can be introduced into a saw band grinding machine. The metal bands are pressed onto a planar guide. The metal band packet is clamped and a grinding machine operates to produce a desired saw tooth profile. A pawl is introduced into a tooth profile which is ground into the metal band packet. The clamped metal band packet is then loosened and advanced with a predetermined tooth spacing.

  • Publication number: 20110000475
    Abstract: A heat reducing slot that is part of a saw blade that includes tips that will house carbide or other tips that are to be attached through a torch or induction. Heat reducing slots repeat for each tip on the perimeter of a blade that will be treated with high heat. For each tip, there is a general area defined near the seat and groove of the tip. In this general area a slot is inserted that has the effect of reducing the amount of heat needed to be applied to the blade for the attachment of carbide or other tips.

  • Publication number: 20100126326
    Abstract: A circular saw blade includes a substantially circular body having a plurality of protruding tip support regions spaced around the periphery thereof, each tip support region including at least a seat for supporting a cutting tip. The tip support region may further include a substantially planar upper tooth face, a grindable tip reinforcement portion and/or a lower tip angle less than 90 degrees. A cutting tip is secured to the seat of each tip support region preferably with a top face of each cutting tip substantially parallel to and offset from an upper tooth face of each tip support region. Each cutting tip of the circular saw blade is further configured to maintain a cutting edge at a substantially constant width when material is removed from the top face thereof. A method of manufacturing a saw blade is also provided.
