It uses an aluminum oxide abrasive grain coating bonded to a high-loft polyester and nylon web backing for consistent cut and extended service life. The Speed-Lok TR (Type III) attachment system allows rapid disc changes without tools on compatible die grinders and handheld disc sanders. At a coarse grade, this disc is suited for moderate material removal while the Clean Bond resin technology resists smearing and loading. Rated to 15,000 RPM, it handles demanding production and service work. Licensed HVAC, plumbing, and pipefitting trades use discs like this for deburring, weld blending, and surface prep on ferrous and non-ferrous pipe and fittings.\u003c\/p\u003e\u003cp\u003eThis disc is appropriate for use on a wide range of materials including 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, cast iron, ductile iron, gray iron, brass, bronze, copper, titanium, super alloys, and fiberglass composites. It is compatible with die grinders and handheld disc sanders that accept Speed-Lok TR or Type R quick-change attachments. Typical install scenarios include pipe weld preparation, flange face conditioning, and fitting cleanup in both shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain for higher cut rate and consistent performance\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon fiber construction extends disc service life\u003c\/li\u003e\n\u003cli\u003eClean Bond resin technology provides smear-free, loading-resistant finishes\u003c\/li\u003e\n\u003cli\u003eSpeed-Lok TR (Type R) attachment for tool-free quick-change on compatible machines\u003c\/li\u003e\n\u003cli\u003eCoarse grade suited for moderate material removal and surface blending\u003c\/li\u003e\n\u003cli\u003eRigid backing for controlled, repeatable stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with die grinders and handheld disc sanders that accept Speed-Lok TR (Type III) or Type R quick-change attachments.
