Patent number: 9782839Abstract: A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot, and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.Type: GrantFiled: January 13, 2011Date of Patent: October 10, 2017Assignee: IRWIN INDUSTRIAL TOOL COMPANYInventors: Joseph Thomas Novak, Matthew Christopher Green

Publication number: 20170232530Abstract: A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.Type: ApplicationFiled: May 3, 2017Publication date: August 17, 2017Inventors: Joseph Thomas Novak, Matthew Christopher Green

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.
