A saw blade includes a cutting portion having consecutive first, second, and third cutting teeth. Each cutting tooth includes a rake surface, a relief surface, and a tip. The first cutting tooth includes a protrusion extending from the relief surface of the first cutting tooth. The cutting portion includes a first gullet positioned between the first cutting tooth and the second cutting tooth and a second gullet sized differently than the first gullet positioned between the second cutting tooth and the third cutting tooth. The cutting portion includes a first pitch extending over the first gullet from the tip of the first cutting tooth to the tip of the second cutting tooth. The cutting portion includes a second pitch different than the first pitch extending over the second gullet from the tip of the second cutting tooth to the tip of the third cutting tooth.

Saw blade including a cutting tooth with a protrusion

A saw blade for use with a power tool includes a body with a first planar surface and a second planar surface opposite the first planar surface. The saw blade also includes an attachment portion that is configured to couple to the power tool. The attachment portion includes a tang and an aperture. The saw blade further includes a cutting edge with a plurality of cutting teeth and a plurality of hexagons formed on the first planar surface. The plurality of hexagons are arranged in a honeycomb pattern in which at least one side of each hexagon is substantially parallel to a corresponding side of an adjacent hexagon.

Reciprocating saw blade

A reciprocating saw blade includes a body including a first end portion, a second end portion opposite the first end portion, and a coupling edge extending between the first and second end portions. The body defines a longitudinal axis extending through the first and second end portions. The reciprocating saw blade also includes an attachment portion coupled to the first end portion of the body and a cutting portion coupled to the coupling edge of the body. The cutting portion includes a plurality of cutting teeth and a plurality of gullets. Moreover, the reciprocating saw blade includes a plurality of slots spaced along the cutting portion to separate the cutting portion into a plurality of cutting segments including a distal end segment adjacent the second end portion of the body. The distal end segment extends beyond the coupling edge of the body in a direction parallel to the longitudinal axis.

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.

A hole saw with various teeth sets and/or sizes that overhang a sidewall is provided. In some embodiments, a large tooth overhangs an inner diameter of the sidewall to create a larger kerf than the sidewall's thickness. Similarly, a tooth set or variations in the circumferential directions of the teeth increase the kerf in a work-piece, either inward or outward. In various embodiments, one or both an enlarged tooth overhang and/or a set of the teeth increases the kerf of the hole saw relative to the sidewall thickness. This results in improved wear resistance, decreased heat on the teeth while cutting, and facilitates slug removal.

Blade for a reciprocating saw

A reciprocating saw blade includes a body defining a longitudinal axis. The blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a protrusion and a tip spaced a first distance from the protrusion. The tip of a first cutting tooth is spaced a pitch distance from the tip of an adjacent second cutting tooth. A gullet is defined between the tip of the first cutting tooth and the protrusion of the adjacent second cutting tooth. The tip of a respective cutting tooth is spaced a tip height distance from a base of the gullet. An apex of the protrusion is spaced a protrusion height distance from the base of the gullet. The protrusion height distance is 65% to 68% of the tip height distance. The first distance is 40% to 77% of the pitch distance.

A reciprocating saw blade includes a body defining a longitudinal axis. The saw blade includes an attachment portion coupled to the body. The attachment portion is able to couple to a reciprocating saw. The saw blade further includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a tip and a protrusion spaced a first distance from the tip. The protrusion of a respective cutting tooth is spaced a first distance from the tip of the cutting tooth in a direction parallel to the longitudinal axis. A gullet is defined between the tip of a first cutting tooth and the protrusion of an adjacent second cutting tooth. The gullet includes a gullet width in a direction parallel to the longitudinal axis. The first distance is greater than the gullet width.
