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.

Patent number: 9434033Abstract: A hole cutter having an extruded plate cap and methods and apparatuses for making such caps and hole cutters. The plate cap has planar opposing external and internal surfaces with an extruded hub extending axially inwardly from the internal surface. An aperture extends axially through the hub from the external surface. At least a portion of the aperture can be threaded for threaded engagement with a driving arbor. The hub is long enough so that the threaded portion contains at least two full threads. A blade body with a cutting edge is attached to the cap to form a hole cutter.Type: GrantFiled: January 13, 2010Date of Patent: September 6, 2016Assignee: Irwin Industrial Tool CompanyInventors: Joseph Thomas Novak, Robert Richard Zielonka, William B.

Patent number: 9370834Abstract: A saw blade including cutting teeth, having at least one of chip-limiters protruding from the teeth or secondary teeth in the gullets of the cutting teeth configured to mitigate the blade from over-feeding. The chip limiters and/or secondary teeth provide that only a limited portion of an object that the saw blade encounters during cutting falls below the cutting tips of the cutting teeth. The chip limiters and/or secondary teeth also assist the cutting teeth in cutting.Type: GrantFiled: March 14, 2013Date of Patent: June 21, 2016Assignee: Irwin Industrial Tool CompanyInventors: Asif Elliston, William B.

Patent number: 9248518Abstract: A recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth suitable for abusive cutting applications. The two consecutive teeth, which may be bi-metal, include a high tooth and a relatively low tooth in comparison to the high tooth. Each high tooth and low tooth include a primary clearance surface defining a relatively shallow primary clearance angle that is about 28° or less, and a secondary clearance surface defining a relatively steep secondary clearance angle in comparison to the primary clearance angle. The primary clearance angle of the high tooth is steeper than the primary clearance angle of the low tooth, such as between about 23° and 28°, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.Type: GrantFiled: June 30, 2010Date of Patent: February 2, 2016Assignee: Irwin Industrial Tool CompanyInventors: Asif Elliston, William B.
