Norton 662530-48994 Type 27 Grinding Wheel 9x1/8x7/8

Product Description

The NORTON 662530-48994 is a Type 27 depressed center grinding wheel engineered for metal grinding applications. Built with Gemini aluminum oxide abrasive, this wheel delivers consistent stock removal on ferrous metals including steel and iron. At 9 inches in diameter and 1/8 inch thick, it is sized for 4.5-inch to 9-inch angle grinders and is rated to a maximum of 6600 RPM. The depressed center profile keeps the wheel face clear of the workpiece edge, allowing flush grinding along surfaces and into corners. This wheel is used by ironworkers, pipefitters, fabricators, and general metalworkers who need a reliable abrasive for weld cleanup, surface prep, and deburring.

This grinding wheel is suited for heavy-duty metal fabrication and maintenance work in industrial, commercial, and field environments. Common applications include weld bead removal, surface conditioning on structural steel, and rough grinding on pipe and plate stock. The Gemini aluminum oxide grain is self-sharpening, which supports consistent cut rate throughout the wheel life. A 7/8-inch arbor bore fits standard angle grinder spindles widely used in the trade.
