A method of manufacturing a saw blade includes providing a coil stock, setting a first portion of the coil stock in a first direction, setting a second portion of the coil stock in a second direction opposite the first direction, and forming a plurality of cutting teeth in the first portion and the second portion of the coil stock after the first and second portions are set.

A circular saw blade includes a circular plate having a diameter, a thickness, a left face, a right face, a peripheral rim, and a central opening couplable to a powered saw. A plurality of alternating teeth and gullets are disposed about the peripheral rim, each tooth having a front face facing generally toward an adjacent gullet in the cutting direction and a recess defined in the front face. A plurality of cutting inserts are affixed in the recesses in the teeth. Each insert has rake face facing generally toward the adjacent gullet in the cutting direction, a relief face extending generally toward the adjacent top face, and a cutting edge at a junction between the relief face and the rake face. Each rake face is disposed at a hook angle between the rake face and a radius of the circular plate intersecting the cutting edge. The relief faces include a plurality of unbeveled relief faces, left-beveled relief faces beveled toward the left face of the circular plate, and a plurality of right-beveled relief faces beveled toward the right faces of the circular plate, arranged in an alternating top bevel with raker (ATB+R) bevel pattern.

A circular saw blade includes a supporting body, cooling channels provided in the inner region of the supporting body and running in the radial direction, and teeth provided in the region of the outer periphery of the supporting body. The cooling channels emerge from the circular saw blade in the region of the tooth bases or in the region of the flanks of the teeth. Furthermore, the circular saw blade has pockets which, starting from a tooth base or a flank of a tooth, extend inwardly into the region of the supporting body.

A method system/apparatus for the streamlined cutting of seeds to sample the seeds and select seeds for planting is disclosed. A method of sampling seeds using such system/apparatus is also provided. The seeds are manually positioned and cut by a serrated cutting tool.

A tip saw has a disc-shape and comprises cutting blade pieces and a base metal. The cutting blade pieces are disposed on blade edges of the tip saw, and each of the cutting blade pieces extends to a reverse rotation side of the each of the cutting blade pieces along an outer side of the tip saw. Two of the cutting blade pieces adjacent to each other partially overlap in a circumferential direction along the outer side of the tip saw. The each of the cutting blade pieces has a cutting edge portion on a rotation side of the each of the cutting blade pieces and a support portion on the reverse rotation side of the each of the cutting blade pieces.

A unique design is provided that may increase the strength and performance and extend the life of a saw blade, particularly when used to cut asphalt. The saw blade may include a main body forming teeth, opposing outer plates secured to each tooth and a cutter secured to each tooth between the respective outer plates. Each tooth can form a recessed section in which a base of cutter main body may be positioned. The outer plates may extend over the recessed section. The outer plates may also extend over a notch formed in a rear face of a rear portion of each tooth. Legs of the outer plates may extend radially inward overtop the main body of the saw blade. A front portion of each tooth and the respective outer plates may extend frontward beyond the respective cutter.

A method and device for controlling the feed rate of a saw blade which is provided with teeth and rotates about a center point relative to a workpiece during a machining process. During a rotation of the saw blade about the center point, the feed rate is selected differently during a machining process effected by teeth of different sectors of the saw blade, wherein the feed rate is selected to be lower during a machining process effected by teeth of sectors having larger radial spacing of the teeth from the center point than during a machining process effected by teeth of sectors having smaller radial spacing of the teeth from the center point. In this way, the operation of the saw blade can be optimized and the service life can be increased.

The present invention relates to a novel cutting apparatus capable of effectively cutting a material via movement in at least two different directions. In certain embodiments, the cutting apparatus comprises cutting elements with at least two cutting surfaces. Such cutting elements are capable of effectively penetrating a material when moved with an applied force in the direction that at least one cutting surface is oriented. Such cutting elements may be configured for use with a variety of cutting apparatus, including but not limited to chainsaws.

Disclosed is a circular toothed blade, formed by a disc (1) having a central hole (2), wherein the blade comprises: a series of protrusions (5) separated by cut-outs (3) and projecting at an angle of 0-90 on the perimeter edge of the disc (1), wherein the protrusion (5) comprises a series of teeth projecting at an angle of 0-90. Also disclosed is a device for cutting ice tubes, which comprises at least one circular blade (A) according to the present invention.

A circular saw blade includes a circular plate-like body having a first side face, an opposite second side face, a periphery, and a central opening defining a center point, and rotatable in a cutting direction. A plurality of circumferentially-spaced teeth are separated by a plurality of gullets. The teeth include a plurality of first beveled teeth with a top face beveled radially inward in a first direction, a plurality of second beveled teeth with a top face beveled radially inward in an opposite second direction, and a plurality of unbeveled teeth. The first beveled teeth, second beveled teeth, and unbeveled teeth are arranged in an alternating top bevel+raker pattern. Each second beveled tooth is disposed radially inward toward the central opening from each first beveled tooth by a first drop distance.
