摘要： An arbor is provided for a hole cutter having an outer surface defining a threaded hole, and a pair of pin holes spaced radially relative to the threaded hole. The arbor has an arbor body defining a threaded end portion threadedly engageable with the threaded hole of the hole cutter, a stop surface formed adjacent to the threaded end portion and spaced radially outwardly therefrom; a drive shank located on another end portion of the arbor body; and a pair of first bearing surfaces located on opposite sides of the arbor body relative to each other and extending axially along a portion of the arbor body between the stop surface and drive shank. A pin ring has an aperture formed therethrough for slidably receiving the arbor body; a pair of drive pins; a second bearing surface that is abuttingly engageable with the hole cutter with the pins received within the corresponding pin holes of the hole cutter; and a pair of third bearing surfaces that are engageable with the first bearing surfaces of the arbor body for preventing relative rotation of the pin support member and arbor body, and are movable axially over the stop surface of the arbor body and engageable with the major diameter of the threaded end portion of the arbor body.

摘要： 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.

摘要： 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. Each of the two consecutive teeth includes a primary clearance surface defining a relatively steep primary clearance angle, a secondary clearance surface defining a relatively shallow secondary clearance angle, a tip, a rake face located on the opposite side of the tip relative to the primary clearance surface, a gullet defining a depth, a first gullet radius located on an opposite side of the gullet relative to the rake face, and a second gullet radius located between the gullet and the rake face, wherein the depth of the gullet is greater than the second gullet radius.

摘要： A hole cutter has a substantially cylindrical blade body that defines an interior surface and an exterior surface that is located on an opposite side of the blade body relative to the interior surface. A cutting edge is located at one end of the blade body that generates swarf in cutting the work piece. A pattern is formed on the exterior and/or interior surfaces of the blade body. The pattern is configured to direct swarf generated at the cutting edge through the path and away from the cutting edge.

摘要： A double-sided saw blade, such as a hack saw blade, comprising a blade body defining a first end and a second end; a first cutting edge located on one side of the blade body defining a first cutting tooth set pattern and a second cutting edge located on an opposite side of the blade body defining a second cutting tooth set pattern; wherein the first set pattern and the second set pattern are (i) timed with respect to one another or (ii) 180 degrees out of phase with respect to one another. A first tooth of the first set pattern may be indexed relative to a designated reference point along the blade body and a first tooth of the second set pattern may be equally indexed relative to the same designated reference point along the blade body.

摘要： A saw blade comprising 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.

摘要： A reciprocating saw blade that includes an elongated blade body defining an inner end and a distal end, a cutting edge located on one side of the blade body and extending between the inner and distal ends thereof and a tang located at the inner end of the blade body. The tang projects from the blade body at an acute angle of at least about 3° relative to a line tangent to an inner end of the cutting edge. The cutting edge includes a portion defining a substantially curved contour and optionally can include at least one further portion defining a non-curved contour.
