Item Name: Covington Parts - Nickel Bond Diamond Cones SKU: COVDNC001 Description: Nickel Bond Diamond Cones are cone-shaped grinding tools made with industrial diamond abrasive held in a nickel bond on a rigid cone body. They are designed for shaping and grinding glass where a tapered profile is useful for reaching into openings, refining inside curves, and cleaning up tight radii that are difficult to access with flat wheels. In glassblowing and lampworking shops, these cones are commonly used during coldworking to true up edges, open or refine holes, and correct small distortions after cutting or drilling. The nickel bond holds the diamond securely for aggressive stock removal on glass, and the cone geometry helps maintain control when working on concave surfaces or interior contours. How it is used: Used on a suitable grinder, flex shaft, or compatible rotary setup to grind and shape glass surfaces Used to refine inside diameters and interior curves where a flat grinding wheel cannot reach cleanly Used with water as a coolant and lubricant to reduce heat, extend abrasive life, and improve surface finish Used to remove sharp edges and to true up openings before moving to finer abrasives and polishing steps
