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 novel cutting method and apparatus includes a cutting blade adapted to consistently and easily form a desirable kerf in a concrete substrate while capturing substantially all resulting concrete dust.

A chain for a work implement has lateral connecting members connected to central driving members via studs. The stud has two lateral portions spaced apart from one another by a collar. A driving member is mounted pivotably on the collar. At the collar the stud has a surface layer harder than the base material. For a high chain service life, the stud has a diffusion layer above a surface layer above the base material. To produce the stud, the stud is provided with a diffusion layer at least at the collar, and a surface region of the collar is hardened, such that a surface layer is formed between the diffusion layer and the base material of the stud. For a method for producing a driving member, the driving member is provided with a diffusion layer at least at a circumferential surface of a hole and the driving member is hardened.

An industrial driver apparatus includes a forklift hydraulic motor, a drive shaft adapter, a hydraulic pump, and a frame. The forklift hydraulic motor includes a housing and a drive shaft. The drive shaft adapter is coupled to the drive shaft of the forklift hydraulic motor and adapts the drive shaft of the forklift hydraulic motor to a dimension of a threaded component being driven by the forklift hydraulic motor. The hydraulic pump pressurizes a hydraulic fluid used to drive the forklift hydraulic motor. The frame is coupled to a housing of the forklift hydraulic motor and prevents the forklift hydraulic motor from rotating while the drive shaft rotates the threaded component.
