Saw blade with set cutting teeth
A saw blade includes an elongated body with a working edge extending along a longitudinal axis. A first strip composed of carbide or cermet and including at least one first full cutting tooth is coupled to a first portion of the working edge by a first weld fusion zone composed of a ductile material. The first strip is set in a first direction at a first angle out of a plane of the body by a first bend in the first weld fusion zone. A second strip composed of carbide or cermet and including at least one second full cutting tooth is coupled to a second portion of the working edge by a second weld fusion zone composed of a ductile material. The second strip is set in a second direction, opposite the first direction, at a second angle out of the plane of the body by a second bend in the second weld fusion zone.
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 WITH HARD METAL CUTTING TEETH
A saw blade includes an elongated body with a working edge extending along a longitudinal axis. A first strip composed of carbide or cermet and including at least one first full cutting tooth is coupled to a first portion of the working edge by a first weld fusion zone composed of a ductile material. The first strip is set in a first direction at a first angle out of a plane of the body by a first bend in the first weld fusion zone. A second strip composed of carbide or cermet and including at least one second full cutting tooth is coupled to a second portion of the working edge by a second weld fusion zone composed of a ductile material. The second strip is set in a second direction, opposite the first direction, at a second angle out of the plane of the body by a second bend in the second weld fusion zone.
Saw blade, saw blade blank, carrier part blank and method for producing a saw blade
A saw blade has at least one carrier part that has at least one cutting side. The saw blade further has a multiplicity of inserts arranged so as to be spaced apart from one another. The inserts are made from a material, in particular a carbide, which is harder than a material of the carrier part. The inserts are each fastened to the at least one cutting side of the carrier part. The inserts each at least partially form at least two saw teeth.
