Constructed with aluminum oxide abrasive grain bonded to a polyester cloth backing, this disc delivers consistent material removal on metal surfaces. At 100 grit, it falls in the fine grade range, making it well-suited for blending, light deburring, and surface prep work before finishing. The disc measures 2 inches in diameter and is rated for a maximum of 25,000 RPM. It is part of the 3M 361F Series and features a blue button attachment for quick mounting and release.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on metals including steel, aluminum, and similar substrates in fabrication, maintenance, and repair applications. Its small 2-inch diameter makes it effective in tight or contoured areas where larger discs cannot reach. The quick-change attachment system allows for fast disc swaps without tools, reducing downtime in production or field service environments. It is commonly used by metal fabricators, maintenance technicians, welders, and industrial service professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100 grit aluminum oxide abrasive for fine-grade surface blending and prep\u003c\/li\u003e\n\u003cli\u003ePolyester cloth backing (YF weight) provides flexibility and durability under load\u003c\/li\u003e\n\u003cli\u003eType R quick-change attachment with blue button for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eRated to 25,000 RPM for use with standard pneumatic and electric die grinders\u003c\/li\u003e\n\u003cli\u003ePart of the 3M 361F Series for consistent abrasive performance\u003c\/li\u003e\n\u003cli\u003eBrown disc color with cloth-backed construction for identification and handling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Roloc TR and Type R quick-change disc holders and mandrels compatible with 2-inch abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the disc button firmly onto a compatible Type R mandrel until it clicks into place.
