Norton 66252842014 Type 27 Grinding Wheel 4x1/8x5/8

Product Description

The NORTON 66252842014 is a Type 27 depressed center grinding wheel designed for metal grinding applications. Built with aluminum oxide abrasive, this wheel delivers consistent stock removal on ferrous metals including steel and iron. The 4-inch diameter, 1/8-inch thickness, and 5/8-inch arbor bore are standard dimensions for use with small to mid-size angle grinders common in fabrication, welding, and maintenance work. At 15,280 RPM maximum operating speed, it suits fast, controlled material removal in demanding job-site and shop environments. Licensed tradespeople and skilled fabricators rely on this wheel type for weld blending, surface prep, and deburring tasks.

This wheel is suited for residential and commercial metalworking applications where a compact 4-inch Type 27 profile is required. Typical install scenarios include post-weld cleanup, pipe fitting prep, and structural steel surface conditioning. The depressed center geometry keeps the mounting hardware clear of the workpiece, allowing a lower grinding angle and improved operator control. Sold individually, with a case quantity of 25 units available for shop and crew stocking.
