Cutoff Wheels and Abrasive Saw Blades

Cut-off wheels and abrasive saw blades are used to cut bars, stock, pipes and other materials that are made of metal, concrete, or masonry. These center-mounted devices consist of an integral shank, pin, shaft, or mandrel that drives a mounted wheel or blades.  Some cut-off wheels are grinding wheels that consist of abrasive grains bonded together by a matrix of resins, epoxy, rubber, metal, and vitrified glass materials. Straight wheels are used in slot cutting applications and have a simple, flat disc shape without any recesses, flaring or cups. Depressed center cut-off wheels that protect mounting hardware from mechanical processes are also available. Sectioning blades consist of very thin superabrasive wheels that are used to slice boules into semiconductor wafers, dice processed wafers into integrated circuit chips or dies, cut optical components, and perform other specialized cutting operations. Saws or cut-off blades with slots are used to remove debris and improve cutting performance.
