A reciprocating saw blade for use with a reciprocating saw, the saw blade including a body including a first substantially planar surface and a second substantially planar surface opposite the first surface, an attachment portion for coupling the saw blade to the reciprocating saw, a cutting edge including a plurality of cutting teeth, and a rib element including a pair of outermost rib members. One of the outermost rib members is proximate the cutting edge and the other of the outermost rib members is proximate a back edge of the blade opposite the cutting edge. Each outermost rib member includes a first portion and a second portion. The first portions of each of the ribs are substantially parallel to one another.

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 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.

A bimetal band saw blade has a cutting edge with a plurality of cutting teeth defining repeating, variable pitch patterns and variable set patterns within pitch patterns. Each relatively heavy set tooth defines a first primary clearance angle, and each unset and relatively light set tooth defines a second primary clearance angle. Each first primary clearance angle is less than or equal to about 20, each second primary clearance angle is less than or equal to about 25, and each first primary clearance angle is within the range of about 4 to about 6 less than each second primary clearance angle. Each unset or light set tooth defines a greater gullet area than a respective heavy set tooth and/or a finer pitch than the respective heavy set tooth. Each tooth defines a positive rake angle within the range of about 3 to about 10.

There is provided a manufacturing method of a band saw blade, including: (a) a step of forming a plurality of saw tooth mounts equipped with cutting blade portions at tip end parts, on a band shaped member at appropriate intervals; and (b) a step of carrying out a chamfering processing by a material removing processing method, on both side edges of a tooth bottom surface in a garret portion formed between respective ones of said saw tooth mounts. By this, there is provided a band saw blade having a plurality of saw tooth mounts equipped with cutting blade portions at tip end parts, on a band shaped member at appropriate intervals, wherein both side edges of a tooth bottom surface in a garret portion formed between respective ones of said saw tooth mounts are chamfering processed by a material removing processing method.

A saw blade includes a body and a cutting portion coupled to an edge of the body. The cutting portion includes a plurality of cutting teeth. The plurality of cutting teeth includes a first tooth form with an abrasive grit and a second tooth form without an abrasive grit.

A blade for use with a reciprocating saw includes an attachment portion configured to couple to the reciprocating saw and a body extending from the attachment portion. The body includes a first portion, a tip portion, and a second portion extending from the first portion to the tip portion. The first portion has a height between about 0.625 inches and about 1.0 inches and the second portion has a height between about 0.18 inches and about 0.25 inches. The blade also includes a blunt tip formed at a distal end of the tip portion. An overall length of the blade is between about 2.4 inches and about 3.25 inches, measured from a proximal edge of the attachment portion to the blunt tip. The blade also includes a plurality of teeth arranged along the second portion and defining a cutting edge.

The disclosure relates to a system having at least one first oscillation insert tool that is configured to be effectively coupled to an oscillation hand power tool, and at least one second oscillation insert tool that differs from the first oscillation insert tool and is configured to be effectively coupled to the oscillation hand power tool as an alternative to the first oscillation insert tool. At least one of the at least two oscillation insert tools comprises at least one compensating unit for at least substantially adapting a mass moment of inertia of the at least one oscillation insert tool to a mass moment of inertia of the at least one second oscillation tool.

A bimetal band saw blade has a cutting edge with a plurality of cutting teeth defining repeating, variable pitch patterns and variable set patterns within pitch patterns. Each relatively heavy set tooth defines a first primary clearance angle, and each unset and relatively light set tooth defines a second primary clearance angle. Each first primary clearance angle is less than or equal to about 20, each second primary clearance angle is less than or equal to about 25, and each first primary clearance angle is within the range of about 4 to about 6 less than each second primary clearance angle. Each unset or light set tooth defines a greater gullet area than a respective heavy set tooth and/or a finer pitch than the respective heavy set tooth. Each tooth defines a positive rake angle within the range of about 3 to about 10.

A saw band (1) includes a chamfered tooth (10) including two effective cutting edge portions (7) being arranged in the region of the chamfer (15) between which an ineffective cutting edge portion (8) of the first tooth (10, 11) is formed. In this way, five cutting channel portions (18) are formed by only two geometrically differently designed teeth (10).
