Built on a non-woven, open-web fiber construction with an aluminum oxide abrasive and resin reinforcement, this disc delivers consistent cut rates while resisting loading on soft metals. At 3\/4 inch in diameter and rated very fine grade, it is suited for light material removal, cleaning, and deburring on flat surfaces and edges. HVAC, mechanical, and fabrication tradespeople use it where fast disc swaps and repeatable surface results are required.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on ferrous and non-ferrous metals and composite materials in moderate industrial applications. Its flexible, pliable web conforms to flat surfaces and some contoured edges without gouging the substrate, making it a practical choice when preparing aluminum, steel, or other metals for coatings, welds, or inspections. The quick change mount reduces downtime during disc changes on compatible angle grinders and die grinders, supporting higher productivity in production and field service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVery fine grade aluminum oxide abrasive for light material removal, cleaning, and deburring\u003c\/li\u003e\n\u003cli\u003eNon-woven open-web construction resists loading on aluminum and other soft metals\u003c\/li\u003e\n\u003cli\u003eFlexible, pliable disc removes burrs and surface contaminants without gouging the substrate\u003c\/li\u003e\n\u003cli\u003eResin-reinforced fiber provides a consistent, high cut-rate and repeatable surface finish\u003c\/li\u003e\n\u003cli\u003eQuick change mount allows fast disc swaps to improve tool efficiency and reduce downtime\u003c\/li\u003e\n\u003cli\u003eWorks on ferrous metals, non-ferrous metals, and composites across flat surfaces and edgework\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with quick change disc holders and compatible angle grinders or die grinders that accept 3\/4 inch quick change discs for surface conditioning applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tradespeople using angle grinders or die grinders equipped with a compatible quick change mandrel. Ensure the tool is powered off and disconnected from its power source before mounting or removing the disc. Inspect the disc for damage before each use and do not exceed the tool RPM rating.
