It uses a non-woven nylon web backing loaded with Vortex agglomerated aluminum oxide grain and bonded with NORTON proprietary Clean Bond resin technology. The coarse 80-grit construction delivers aggressive stock removal while the high-loft nylon fiber construction conforms to irregular surfaces. The Type R (Roloc-compatible) attaching system allows fast one-handed disc changes on handheld disc sanders. Rated to a maximum of 15,000 RPM, this disc suits demanding metalworking environments where consistent finish quality and disc longevity matter.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for use on a wide range of ferrous and non-ferrous metals in fabrication, welding, and maintenance applications. Typical uses include weld blending, deburring, and surface preparation on 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, gray iron, brass, bronze, and copper. It also performs on fiberglass and composite substrates. It is installed on handheld disc sanders in both shop and field environments by metalworkers, fabricators, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVortex agglomerated aluminum oxide grain for consistent cut rate and long disc life\u003c\/li\u003e\n  \u003cli\u003eHigh-loft nylon web backing conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eClean Bond resin technology maintains grain anchorage under heat and load\u003c\/li\u003e\n  \u003cli\u003eType R quick-change attaching system enables fast one-handed disc swaps\u003c\/li\u003e\n  \u003cli\u003eCoarse 80 grit suited for weld blending and aggressive surface conditioning\u003c\/li\u003e\n  \u003cli\u003eRated to 15,000 RPM maximum for use on standard handheld disc sanders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Type R (Roloc-compatible) quick-change handheld disc sanders.
