3M 7000028427 Unitized Cut Polish Wheel 2x1/8x1/4 7A Med

Product Description

The 3M 7000028427 is a unitized abrasive wheel engineered for tough blending and finishing work across metal fabrication, welding cleanup, and surface conditioning applications. This wheel measures 2 inches in diameter by 1/8 inches wide with a 1/4-inch arbor hole. It is built with a layered, durable unitized construction rated at a hard density of 7, which provides low conformability for consistent, aggressive stock removal. The abrasive mineral is medium-grade aluminum oxide, delivering reliable cut and polish performance on ferrous and non-ferrous metals. Designed for long service life, this wheel holds up under repeated use in demanding shop and field environments.

This unitized wheel suits residential and commercial metalworking tasks including weld blending, deburring, and surface finishing on flat and contoured workpieces. Its hard density and medium-grade cut make it a practical choice for fabricators, maintenance technicians, and industrial tradespeople who need consistent finishing results without frequent wheel changes. It is compatible with right-angle grinders and die grinders fitted with a 1/4-inch mandrel.
