An object of the present invention is to provide a dicing blade which does not cause cracking and breaking even in a workpiece formed from a brittle material, and can stably perform cutting process in a ductile mode on the workpiece with high precision. A dicing blade 26 which performs the cutting process on the workpiece is integrally formed of a diamond sintered body 80 which is formed by sintering diamond abrasive grains 82 so as to have a discoid shape, and a content of the diamond abrasive grains 82 of the diamond sintered body 80 is 80 vol % or more. It is preferable that recessed parts which are formed on a surface of the diamond sintered body 80 are continuously provided in an outer circumferential part of the dicing blade 26 along a circumferential direction.

The present disclosure provides a brazing bond type diamond tool having excellent cuttability. The diamond tool includes a shank having a body with a thickness of 2 mm or less and a tip portion formed along an edge of the body, the tip portion being thinner than the body; and a brazing bond layer formed on the tip portion of the shank to secure diamond particles having a particle size of 25 to 50 mesh with a brazing bond, wherein the brazing bond layer has a greater thickness than a difference between half the thickness of the shank body and half the thickness of the shank tip portion, such that some part of the shank body can penetrate into a surface of an object to be cut, and the tip portion of the shank has a curved surface at an end thereof.

A wafer edge trim blade includes a round blade body and at least one slot formed inward from an outside edge of the round blade body. The at least one slot is configured to remove debris generated during wafer edge trimming using the wafer edge trim blade.

A spacer, blade core, assembly and methods for blade and blade core assemblies, including gang blade heads, include openings in blade cores for receiving spacers. A spacer and its opening can be the same shape or different shapes, and spacers can be interconnected or disconnected from each other. A spacer can be in contact or engaged with two blades, three blades, or more.

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. A saw blade may include a main body forming teeth and cutters that are secured to the teeth. The cutters may be configured to extend outwardly beyond sides of the main body to minimize wear of the main body. The cutters could be configured to extend from alternating sides of the main body to create a greater effective cutting width.

A grinding tool, such as a cutting disc, includes a matrix, in particular a sintered metal matrix, and diamonds embedded in the matrix. At least the majority of the diamonds are each assigned at least one wear-promoting particle and/or at least one wear-inhibiting particle. The at least one wear-promoting particle and the at least one wear-inhibiting particle are likewise embedded in the matrix.

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 spacer, blade core, assembly and methods for blade and blade core assemblies, including gang blade heads, include openings in blade cores for receiving spacers. A spacer and its opening can be the same shape or different shapes, and spacers can be interconnected or disconnected from each other. A spacer can be in contact or engaged with two blades, three blades, or more.

A circular saw blade includes an arbor located in a center of the body, a bore positioned in the arbor and configured to fit on a power tool shaft, a plurality of cutting teeth spaced along an outer edge of the body, and a plurality of openings formed in the body between the plurality of cutting teeth and the arbor. The plurality of openings includes a first opening and a second opening disposed radially inward from the first opening relative to the center of the body. The second opening at least partially overlapping the first opening in a circumferential direction, a radial direction, or both.
