Reciprocating saw blade with plunge nose
A reciprocating saw blade includes a body formed from a piece of coil stock. The body has a shank end configured to secure the blade with a reciprocating saw, a plunging end configured to enter a workpiece, and a cutting edge and opposite back edge extending between the shank end and the plunging end. The cutting edge has a plurality of teeth arranged in a pattern that includes left and right set teeth. A plurality of gullets is disposed between adjacent teeth. Each of the teeth and the gullets has substantially the same size, except that the first and third consecutive teeth immediately adjacent the plunging end have been flattened to be unset, and at least a portion of the second consecutive tooth has been removed to form an enlarged gullet between the first and third teeth.
Reciprocating saw blade with tangs on each end and related method
A reciprocating saw blade has a first end with a first tang and a second end with a second tang. The first and second tangs are alternatively engageable with the chuck of a reciprocating saw. The reciprocating saw blade defines a substantially uniform cutting edge extending from approximately the first end to approximately the second end of the blade. The first tang is engageable with the chuck of the reciprocating saw for fixedly securing the first end of the blade to the reciprocating saw and forming with the second tang the free end of the saw blade. Alternatively, the second tang is engageable with the chuck of the reciprocating saw for fixedly securing the second end of the blade to the reciprocating saw and forming with the first tang the free end of the reciprocating saw blade drivable in a reciprocating motion by the reciprocating saw.
Saw blade with tooth form projection
A saw blade, such as a metal-cutting band saw blade, has a cutting edge including a plurality of teeth. A plurality of the teeth include a tip, a clearance surface located on one side of the tip, a rake face located on an opposite side of the tip relative to the clearance surface, a gullet, and a substantially flat, linear, or non-curvilinear projection formed between the rake face and the gullet and projecting outwardly relative to the rake face. The projection is inclined at an acute angle relative to a plane extending between the tips of consecutive unset teeth. The projection defines an inner end adjacent to the rake face and an outer end adjacent to the gullet. The inner end is located at a depth below the tip of at least about 25/1000 inch, and the distance between the inner end and the outer end of the projection in a direction substantially parallel to the plane extending between the tips of at least two teeth is less than about 65/1000 inch.
Saw blade and method of shaping a back edge of a saw blade
A saw blade includes a first edge having teeth and a second edge principally opposed to the first edge, which second edge extends in a first principal direction of extension along a first part of its principal extension and in a second principal direction of extension along a second part of its principal extension, neither said first nor said second principal direction of extension being parallel to a principal direction of extension of said first edge, but said first principal direction of extension forming a first and positive angle (A) with said principal direction of extension of said first edge and said second principal direction of extension forming a second and negative angle (B) with said principal direction of extension of said first edge.
Asphalt saw blade
A unique design is provided that increases the strength and extends the life of an asphalt saw blade. The asphalt saw blade may include a main body, outer plates and cutters that are secured to the main body and outer plates via a notched interface. The cutters can include cutting elements and a plate that reinforces the cutting elements while also shielding the cutter's main body from wear.
Saw blades and methods of machining saw blade tooth profiles of saw blades
Saw blades and methods of machining saw blade tooth profiles of saw blades. The saw blades include a blade body and a plurality of teeth defined by the blade body. Each tooth includes a tooth back, a tooth tip, a tooth face, and a tooth gullet. In at least one tooth, a relief region extends toward the tooth back and separates the tooth face from the tooth gullet. The methods include supporting the saw blade with a blade support structure and advancing the saw blade with a blade advance structure. The methods also include dry-machining a finished tooth profile in a working portion of the saw blade in a single pass. The dry-machining includes dry-machining with an end mill by operatively translating the end mill relative to the saw blade and within a plane that is at least substantially perpendicular to an end mill rotational axis of the end mill.
Reciprocating saw blade with curved cutting edge
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.
SAW BLADE
A reciprocating saw blade including a body, an attachment portion, a cutting portion formed on the body including a plurality of cutting teeth, and a plunge point for initiating a plunge cut including a plunge tooth and a leading gullet between the plunge tooth and a first tooth of the plurality of cutting teeth. A first angle of the rake face of the plunge tooth is measured through the plunge tooth. A second angle of the rake face of the first cutting tooth is measured through the first cutting tooth. One of the first angle and the second angle is greater than 90 degrees and the other is less than 90 degrees. At least the first cutting tooth is set. The rake face defining the first angle is spaced from the rake face defining the second angle by a distance greater than the pitch of the plurality of cutting teeth.
Tooth formations and arrangement for a saw blade
A saw blade can include a blade body having a cutting edge defined by multiple teeth. The teeth can be disposed in a repeating pattern including a raker tooth, a first set tooth having a light offset to a right side of the blade body, a second set tooth having a heavy offset to the left side of the blade body, a second raker tooth, a third set tooth having a light offset to the left side, and a fourth set tooth having a heavy offset to the right side of the blade body. Each tooth can include a tip, rake face, gullet having a gullet depth, and one or more clearance surfaces. The pitch distance and gullet depth of the heavy offset teeth can be less than the pitch distances and gullet depths of the remaining teeth to provide an increased amount of strength for the heavy offset teeth.
BAND SAW BLADE WITH IMPROVED BACK EDGE
A band saw blade can include a body extending in an endless ribbon, a cutting edge with cutting teeth, a back edge opposite the cutting edge, and a series of notches formed in the back edge. The notches can at least include first, second and third different notches. The notches can be arranged in a repeating pattern and each can be continuously arcuate. The notches can extend into the back edge a first depth. The notches can be separated from one another by a first distance. The notches can have respective radii of curvature and the radii of curvature can be different from one another.
