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 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, including a sidewall and an endcap, is provided. The endcap includes projections that fit within notches of the sidewall to form a brazed or welded joint that couples the endcap to the cylindrical sidewall. The projections extend through the notches and are brazed or welded to the base of the sidewall. The endcap couples to the sidewall to form a cylindrical hole saw body. The endcap rotates and supports the hole-saw during operation.

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 tool, such as a hole saw, including an open end cap geometry is provided. The end cap includes spokes extending between a hub and a rim. A plurality of openings are defined between the spokes, hub and rim. The area of the openings is substantially large relative to the area of the end cap such that the end cap is relatively lightweight and provides access into the hole saw for debris removal. The spokes are shaped and positioned to provide strength to the end cap.

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.

A saw blade for use with a reciprocating saw includes a body and an attachment portion extending from the body. The attachment portion includes a tang and an aperture configured to connect 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, and first and second floor guard teeth spaced apart and positioned adjacent at least one of the plurality of cutting teeth. Each cutting tooth has a tip that defines a plane. The body has a first height measured generally perpendicularly from a back edge of the body to the plane. The attachment portion has a second height measured generally perpendicular to the plane. A ratio of the first height to the second height is between approximately 4 and approximately 5. The first and second floor guard teeth extend beyond the plane.

A reciprocating saw blade includes a body having a first end portion, a second end portion, and a plunge point formed on the second end portion of the body. The plunge point includes a leading tooth and a leading gullet. The leading tooth includes a rake face and a tip. The leading gullet includes a base extending from the rake face of the leading tooth to the plurality of cutting teeth. The plunge point includes a second tooth protruding from the base of the leading gullet. The second tooth includes a tip positioned further from the base of the leading gullet than the tip of the second tooth in a direction transverse to a longitudinal axis of the body. The cutting portion also includes a plurality of gullets formed between a plurality of cutting teeth. The leading gullet is larger than each gullet of the plurality of gullets.
