Each tooth top corner part of a hard tip of the first following tooth, a tooth top corner part on a left side of a hard tip of the second following tooth, and a tooth top corner part on a right side of a hard tip of the third following tooth most outwardly protrude in a left-right direction.

Saw blade

A saw blade includes a body and a plurality of cutting teeth formed on the body. Each cutting tooth includes a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. Each gullet forms an undercut portion between the body and the projection of each cutting tooth.

A saw blade includes a body, saw blade teeth disposed on a first edge of the body, and a ramp element disposed on a second edge of the body, the second edge opposing the first edge. The ramp element is repeated along the longitudinal axis of the body to define a ramp element pattern. The ramp element includes a rise portion disposed proximal to a cutting direction of the saw blade and a relief portion disposed distal to the cutting direction of the saw blade. At least one of the rise portion and the relief portion of the ramp element defines a variable curve geometry.

20200290140 · 2020-09-17 ·

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.

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.

20200246888 · 2020-08-06 ·

A wood cutting band saw blade includes a band having a continuous band portion and having on at least one length-wise edge a plurality of teeth. The plurality of teeth extend upward from the continuous band portion, and the length-wise edge extends in a horizontal direction. Each tooth includes a cutting edge and a back angle edge defining a tip. Each tooth also includes a gullet having a forward edge extending upward from a location at a lowest extent of the gullet to the back angle edge. The gullet further includes a rearward edge extending upward from a vertical level at the lowest extent of the gullet to a cutting edge of an adjacent tooth. The location at the lowest extent of the gullet is closer to the tip than to a tip of the adjacent tooth.

RECIPROCATING SAW BLADE

A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.

Reciprocating saw blade

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.

Reciprocating saw blade with plunge nose
