4-1/2” Hub Grinding Disc

Grind and shave metal and make quick and easy disc changes with the FLEX 4-1/2” Hub Grinding Disc. This 4.5-inch grinding disc features a hub arbor design that allows the disc to be screwed on, eliminating the need for a locking nut. The disc’s aluminum oxide grain delivers quick material removal without generating excessive heat for use with steel, stainless steel, non-ferrous metals, and cast iron. Its depressed center allows ample clearance when working at a constrained angle for shallow angle grinds. Its iron- and sulfur-free construction reduces oxidizable particles left behind on finished surfaces to help prevent rust, while a coating slows moisture exposure for extended disc life. Three full-face fabric layers hold this disc together for added stability and safety during use.
