Publication number: 20240051045Abstract: A saw blade includes an elongated body with a working edge extending along a longitudinal axis. A first strip composed of carbide or cermet and including at least one first full cutting tooth is coupled to a first portion of the working edge by a first weld fusion zone composed of a ductile material. The first strip is set in a first direction at a first angle out of a plane of the body by a first bend in the first weld fusion zone. A second strip composed of carbide or cermet and including at least one second full cutting tooth is coupled to a second portion of the working edge by a second weld fusion zone composed of a ductile material. The second strip is set in a second direction, opposite the first direction, at a second angle out of the plane of the body by a second bend in the second weld fusion zone.Type: ApplicationFiled: October 16, 2023Publication date: February 15, 2024Inventors: POINON SANOGO, ASIF ELLISTON, MATTHEW CHRISTOPHER GREEN, DOUGLAS FOSBERG, STEVE HAMPTON, ASHKAN SHARIFI, JOSEPH T. NOVAK, KURT LANGHELD, WILLIAM B. KORB

Publication number: 20240042535Abstract: 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.Type: ApplicationFiled: July 28, 2023Publication date: February 8, 2024Inventors: Ashkan Sharifi, Jarrod A. Coletta, Asif A. Elliston, Mehdi Sebaradar, Kenneth Hall

Patent number: 11813683Abstract: A saw blade includes an elongated body extending along a longitudinal axis and having an elongated cutting edge. A first hard metal strip is attached to a first portion of the cutting edge and includes at least one first full hard metal cutting tooth that is set left at a first angle relative to a vertical axis of the body that is generally perpendicular to the longitudinal axis. A second hard metal strip attached to a second portion of the cutting edge and includes a second full hard metal cutting tooth that is set right at a second angle relative the vertical axis.Type: GrantFiled: November 26, 2019Date of Patent: November 14, 2023Assignee: BLACK & DECKER INC.Inventors: Poinon Sanogo, Asif Elliston, Matthew Christopher Green, Douglas Fosberg, Steve Hampton, Ashkan Sharifi, Joseph T. Novak, Kurt Langheld, William B. Korb

Publication number: 20230042627Abstract: A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.Type: ApplicationFiled: August 5, 2022Publication date: February 9, 2023Inventors: POINON Z. SANOGO, ASIF ELLISTON, DOUGLAS K. FOSBERG, JR., MATTHEW CHRISTOPHER GREEN, STEPHEN A. HAMPTON, ASHKAN SHARIFI, ANDREW C. REIST, MEHDI SEBARADAR, JOSEPH T. NOVAK, KENNETH HALL
