It measures 1 inch in diameter and cuts at 180 grit, placing it in the very fine to fine grade range. The disc is constructed with aluminum oxide abrasive bonded to a rigid, X-weight 2-ply polyester backing, providing durability and a faster cut rate compared to lighter-backed alternatives. With a maximum rated speed of 40,000 RPM, it is built to handle the demands of precision deburring, surface cleaning, and detailing work. Licensed trades and shop fabricators install this disc type for fast, consistent results on tight geometries.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for deburring, cleaning, and detailing applications across a range of metals including 300 Series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Its rigid polyester backing maintains consistent contact on flat and near-flat surfaces. The small 1 inch diameter makes it appropriate for detailed work, edge finishing, and confined areas where larger discs cannot reach. It is used in fabrication, maintenance, and finishing environments where surface condition and dimensional tolerance matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180 grit aluminum oxide abrasive for very fine deburring, cleaning, and surface detailing\u003c\/li\u003e\n  \u003cli\u003ePower-Lock Type R quick-change attachment system for fast disc swaps without additional hardware\u003c\/li\u003e\n  \u003cli\u003eX-weight 2-ply polyester backing rated rigid for consistent, stable cutting contact\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 40,000 RPM compatible with standard handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eSuitable for 300 Series stainless, brass, bronze, hard carbon steels, soft carbon steels, and titanium\u003c\/li\u003e\n  \u003cli\u003eSeries R766 construction with coating applied over backing for extended disc life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with handheld disc sanders equipped with a Power-Lock Type R quick-change hub.
