083848000 | Plural tooth groups | 12 |
20090044679 | Band saw blade with interior teeth - A planar band saw blade having an outer cutting edge with a plurality of saw teeth also includes sets of secondary teeth placed in cutout portions along a centerline of the band saw blade. The secondary tooth sets provide portions within the body of the saw blade that provide additional cutting action that reinforces the primary outer cutting edge of the blade. The band saw blade may include teeth on each parallel edge and the interior tooth sets in each cutout portion alternatively point toward opposite edges. | 02-19-2009 |
20100126328 | JIGSAW BLADE FOR HAND-HELD POWER JIGSAWS - A jigsaw blade having a clamping end and, adjoining it, a blade-like working body that has a row of saw teeth that is inclined in relation to the clamping end, a spine on the opposite side from the row of teeth, and a tip at the front is therefore safer, easier to use, has higher performance, and is more precise. The jigsaw blade has two tooth row regions of the row of saw teeth that are inclined at different angles in relation to the clamping end. | 05-27-2010 |
20100212472 | Pair of saw blades - A pair of saw blades includes a first blade, which is adapted to rotate in a first direction about an axis of rotation, and a second blade, which is adapted to rotate in a second direction opposite to said first direction about the same axis of rotation. Each blade has a blade body and cutting elements, which are provided along the periphery of the blade body and adapted to run close and in parallel to each other when the blades are rotating. A spacer, which extends into a space between the two blades, is attached to at least the blade body of one of the blades in order to support itself against and slide along a peripheral part of the other opposite blade. | 08-26-2010 |
20120000338 | SAW BLADE TOOTH FORM FOR ABUSIVE CUTTING APPLICATIONS - 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 blade defines a relatively coarse tooth pitch. 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. | 01-05-2012 |
20130160631 | Jab Saw Accessory Tool for an Oscillating Tool - An accessory for a power tool, includes a mounting portion configured to mate with an oscillating drive member of a power tool. A support arm portion extends from the mounting portion in a first direction. The support arm portion includes an inner edge that faces in a second direction transverse to the first direction. A blade portion extends from the support arm generally in the second direction. The blade portion includes a trailing edge arranged facing generally toward the mounting portion and a leading edge arranged facing generally away from the mounting portion. The trailing edge and the leading edge portion meet to define a pointed tip portion. | 06-27-2013 |
20150096422 | OSCILLATING SAW BLADES - A saw blade for an oscillating saw can include a plate having cutting teeth arranged in an arcuate tooth pattern at a cutting path. Cutting teeth on opposite sides of the centerline of the plate may be arranged to face oppositely. Each cutting tooth can have primary and secondary relief surfaces at different angles to the cutting path. Cutting teeth may be offset outwardly from the plate, with tips of some of the cutting teeth having outward-facing kerf surfaces parallel to the plate. The plate may be of bimetal construction, so that the cutting teeth and bulk of the plate are made of different materials. The cutting teeth may be formed by a coining process. | 04-09-2015 |
20150367434 | SAW BLADE WITH MULTIPLE TANGS - A saw blade includes an elongated body having a front end, a rear end, an elongated cutting edge extending between the front edge and the rear edge and defining a longitudinal axis, and a back edge opposite the cutting edge. A first tang is coupled to the rear end of the body and configured to couple the saw blade to a saw. The first tang faces a rearward direction away from the front end of the body. A second tang is defined in an intermediate portion of the body and configured to couple the saw blade to a saw. The second tang also faces the rearward direction. The second tang can be exposed by breaking off a portion of the body. | 12-24-2015 |
20160059329 | CIRCULAR SAW BLADE - The circular saw blade includes a blade body having the form of a disc, and a plurality n (n>1) of teeth inserted into the peripheral rim of the blade body so as to be distributed over the circumference of the disc. Each tooth generates a chip derived from the machined material. There is a cut-out for the clearance of the chip being provided in the peripheral rim of the blade body at the level of each tooth, and incorporating a base seat to which the tooth is soldered. For at least one tooth, the cut-out defines a volume for clearance of the chip which is less than the apparent volume of the chip generated by a tooth. | 03-03-2016 |
083849000 | Including raker tooth group | 4 |
20120090443 | SAW BLADE - A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis and an attachment portion. The attachment portion includes a tang and an aperture configured to couple to the reciprocating saw. The saw blade also includes a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth. Each cutting tooth including a tip, a rake face extending from the tip generally toward the longitudinal axis and at least partially defining a gullet, a relief surface extending from the tip and having a first end that is closer to the attachment portion and a second end that is further from the attachment portion, and a protrusion extending from the second end of the relief surface. The protrusion of each tooth inhibits a nail from entering the gullet and contacting the rake face of an adjacent tooth during cutting operations. | 04-19-2012 |
20130180375 | RECIPROCATING SAW BLADE - A reciprocating saw blade includes a body, and the body includes a connecting portion for connecting the blade to the saw, and a cutting edge. The cutting edge includes a plurality of teeth organized in an overall tooth set pattern. The overall tooth set pattern approximately corresponds to the stroke length of the reciprocating saw. By the overall tooth set pattern corresponding to the stroke length of the reciprocating saw, the cut time is decreased, the life of the blade is increased, the vibration is minimized and/or a smoother finishing cut is enabled. | 07-18-2013 |
20160008899 | Variable Pitch Blade | 01-14-2016 |
20160158858 | RECIP BLADE - A recip blade has a cutting edge defining a cutting direction and a repeating pattern of cutting teeth. Each repeating pattern includes (i) a leading tooth with respect to the cutting direction that includes a rake face defining a first rake angle that is negative, and (ii) a trailing tooth following the leading tooth with respect to the cutting direction that includes a rake face defining a second rake angle that is less negative than the first rake angle. | 06-09-2016 |
