Sized at 3 inches and rated Extra Coarse at R80P grit, this disc features 100% ceramic grain that continuously fractures during use, constantly exposing fresh, sharp cutting edges. This design delivers high stock removal rates while keeping overall abrasive cost low. A self-lubricating grain treatment controls heat buildup during grinding, making it well suited for heat-sensitive metals. The TR quick-change attachment system allows fast disc swaps without tools, reducing downtime on production grinding tasks. Licensed metalworkers, fabricators, and weld shop technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis disc is built for demanding grinding, weld blending, and deburring applications on hard-to-grind materials. It performs particularly well on 300 Series and 400 Series stainless steel, as well as exotic alloys where heat generation and grain breakdown are common problems with standard abrasives. The Extra Coarse grit level prioritizes speed of cut over surface finish, making it the right choice for initial stock removal and heavy weld blend-down rather than finishing passes. Discs are sold in boxes of 25.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100% ceramic grain fractures continuously to expose sharp cutting edges throughout disc life\u003c\/li\u003e\n  \u003cli\u003eSelf-lubricating grain treatment reduces heat buildup for cooler cutting on stainless and exotic alloys\u003c\/li\u003e\n  \u003cli\u003eImproved resin bond system maximizes grain retention for extended disc life\u003c\/li\u003e\n  \u003cli\u003eExtra Coarse R80P grit delivers fastest stock removal, weld blending, and deburring rates\u003c\/li\u003e\n  \u003cli\u003eTR quick-change attachment system allows tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eCA ceramic abrasive cloth backing supports aggressive grinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TR quick-change disc holders and compatible right-angle grinders or die grinders that accept the TR attachment system.
