3M 7000045169 Quick-change Disc 2 in 36 Grit Ceramic Roloc Tsm

Product Description

The 3M 7000045169 is a quick-change abrasive disc designed for aggressive material removal in grinding, blending, and surface prep applications. Part of the 984F series, it features a ceramic abrasive grain bonded to a polyester cloth backing rated at YF weight, delivering consistent cut on hard metals and welds. The disc measures 2 inches in diameter, carries a 36-grit very coarse grade, and is rated for a maximum of 25,000 RPM. It uses a Type S attaching system compatible with Roloc TSM quick-change holders, allowing fast disc swaps without tools. Licensed HVAC sheet metal workers, pipefitters, and fabricators handling ductwork, fittings, and structural metal will find this disc a practical consumable for daily use.

This disc suits light fabrication shops, HVAC sheet metal operations, plumbing rough-in work, and general metal prep where a small-diameter, fast-cutting disc is needed in tight or awkward spaces. The 2-inch form factor fits compact right-angle grinders and die grinders commonly used on pipe ends, weld seams, and burr removal. The ceramic grain self-sharpens during use, maintaining cut rate longer than aluminum oxide alternatives on steel and stainless. Each package contains one disc, with a minimum order quantity of 50 units.

Installation Notes

Installation and disc changes should be performed by a qualified tradesperson with the grinder power source disconnected or the tool powered off and fully stopped. Inspect the disc for cracks or damage before mounting and confirm the spindle speed of the tool does not exceed the 25,000 RPM rating marked on the disc. Eye protection, hearing protection, and appropriate PPE are required during grinding operations per OSHA and tool manufacturer guidelines. Do not apply side-loading force beyond the disc and backing design intent.
