It uses aluminum oxide grain on a flexible non-woven polyester and nylon web backing, rated to a maximum of 15,000 RPM. The Type S attaching system allows fast disc swaps without additional hardware. Medium grade makes it suited for moderate material removal, blending, and surface prep. This disc is installed and used by metal fabricators, maintenance techs, and industrial tradespeople working on grinders and handheld disc sanders.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use on 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass and composite materials. It is compatible with die grinders, inline grinders, straight grinders, and handheld disc sanders. The flexible non-woven construction allows the disc to conform to irregular or contoured surfaces, making it practical for weld blending, deburring, and light stock removal in fabrication and maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain for higher cut rate on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon fiber construction extends disc service life\u003c\/li\u003e\n\u003cli\u003eClean Bond resin technology helps prevent smearing and loading on finished surfaces\u003c\/li\u003e\n\u003cli\u003eFlexible non-woven backing conforms to contoured and irregular workpiece geometry\u003c\/li\u003e\n\u003cli\u003eType S quick-change attaching system for fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eMedium grade suitable for moderate material removal and surface blending\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with die grinders, inline grinders, straight grinders, and handheld disc sanders accepting a Type S quick-change attachment system.
