Built on a fiber backing with a premium ceramic alumina abrasive, this disc delivers consistent stock removal across its service life. The 36-grit, extra-coarse cut rating makes it suitable for rapid grinding, deburring, and scale removal. It attaches via a Quick Change TN hub, allowing fast disc swaps without additional tooling. Rated to a maximum of 8,600 RPM, it is engineered for use on right-angle grinders and disc sanders equipped with a compatible TN-style holder. The purple 1182C series coating indicates the ceramic alumina abrasive formulation.\u003c\/p\u003e\u003cp\u003eThis disc is used in industrial, fabrication, and maintenance settings where fast, controlled material removal is required on ferrous and non-ferrous metals. Typical applications include weld blending, edge chamfering, rust and scale removal, and rough surface conditioning. It is commonly specified by metal fabricators, pipefitters, ironworkers, and maintenance technicians working on structural steel, pipe, and sheet metal. The extra-coarse grit is appropriate for initial stock removal passes rather than finish work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePremium ceramic alumina abrasive for fast cut rate and extended disc life\u003c\/li\u003e\n\u003cli\u003e36 grit extra-coarse grade suited for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eQuick Change TN attachment for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eResinoid bond construction provides durability under load\u003c\/li\u003e\n\u003cli\u003eFiber backing supports consistent abrasive contact on curved and flat surfaces\u003c\/li\u003e\n\u003cli\u003e8,600 RPM maximum speed rating for use on standard right-angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with right-angle grinders and disc sanders fitted with a Quick Change TN-style hub or holder.
