FLEX FL-FA303003 4-1/2in 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.\r\nFeatures:\r\n\r\nHUB ARBOR DESIGN -Allows disc to be screwed on, eliminating need for locking nut\r\nALUMINUM OXIDE GRAIN -Quickly removes material while maintaining reduced heat\r\nDEPRESSED CENTER -Allows for clearance when working at a constrained angle\r\nRIGID CONSTRUCTION -Three full-face fabric layers hold the disc together for added stability and safety during use\r\nIRON- AND SULFUR-FREE CONSTRUCTION -Reduces oxidizable particles on finished surface to help prevent rust\r\nRESISTS MOISTURE -Disc coating slows moisture exposure for extended life\r\n\r\nSpecifications:\r\n\r\nDiameter: 4.5 in\r\nThickness: 0.28 in\r\nArbor Diameter: 5/8-11 in\r\nWheel Type: Grinding Disc\r\nType: 27\r\nMAX RPM: 13,300 RPM\r\nMax.
