Running at up to 30,000 RPM, this 3-inch disc uses a Quick-Change Type R attachment for tool-free mounting on compatible right-angle grinders. The zirconia alumina abrasive delivers aggressive stock removal with extended disc life compared to standard aluminum oxide. At 120 grit fine grade, it suits finishing passes where a smooth surface is needed after rough grinding or weld cleanup. The fiberglass backing resists flex fatigue under load and keeps the disc stable at high RPMs.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metalworking trades including fabricators, pipefitters, and maintenance mechanics working on weld seams, surface scale, and edge prep. The Type 27 flat profile allows flat-surface and slight-angle grinding. The Quick-Change Type R hub makes it practical for repetitive disc swaps in production environments or field service work where downtime matters. It ships and is sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina abrasive for long disc life and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade for finishing and light material removal\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile for flat-surface and low-angle grinding\u003c\/li\u003e\n\u003cli\u003eQuick-Change Type R attachment for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eFiberglass backing for rigidity and stability at high RPM\u003c\/li\u003e\n\u003cli\u003e30,000 RPM maximum speed rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with right-angle grinders fitted with a Quick-Change Type R hub adapter.
