The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

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 reciprocating saw blade includes a body defining a longitudinal axis. The saw blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face at least partially defining a gullet, a relief surface, and a protrusion extending from an end of the relief surface. The protrusion of each cutting tooth inhibits a nail from entering the gullet. The tips of the plurality of cutting teeth define a first plane that is generally parallel to the longitudinal axis and the protrusions of the plurality of cutting teeth define a second plane that is generally parallel to the longitudinal axis. A distance between the first plane and the second plane is at most 0.035 inches, and a distance between the protrusion of one cutting tooth and the tip of an adjacent cutting tooth, measured generally parallel to the longitudinal axis, is 0.08 inches.

An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

A saw blade for a machine tool driven oscillatingly about a longitudinal axis has at least one cutting edge, on which, at least in part, abrasive particles are provided. The saw blade is suitable, in particular, for sawing fiber composites.

A band saw blade may include a cutting edge defined by a number of teeth. Each tooth may include a tip, a rake face, a primary clearance surface defining a primary relief angle, a secondary clearance surface defining a secondary relief angle greater than the primary relief angle, a tertiary clearance surface defining a tertiary relief angle greater than the secondary relief angle, a first curvilinear protrusion formed between the secondary clearance surface and the tertiary clearance surface, a gullet surface, and a second curvilinear protrusion formed between the rake face and the gullet surface. The teeth may be spaced at varying pitch distances such that a difference between a minimum teeth per inch (TPI) based on a maximum pitch distance and a maximum TPI based on a minimum pitch distance is equal to or greater than 1, and may define a kerf width between 0.115 inches to 0.140 inches.

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.

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.

An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.
