Norton 66252842005 Type 27 Grinding Wheel 4x1/8x5/8

Product Description

The NORTON 66252842005 is a Type 27 depressed center grinding wheel built for light grinding and cutting on metal. Part of the NorZon Plus abrasive line, it features a depressed center profile that keeps the grinding face at a consistent angle during use, reducing fatigue and improving control. The wheel measures 4 inches in diameter, 1/8 inch thick, and accepts a 5/8 inch arbor. At a maximum operating speed of 15,280 RPM, it suits angle grinders commonly used in fabrication, maintenance, and field metalwork. Licensed tradespeople and skilled metalworkers are the primary installers and users of this product.

This wheel is suited for light grinding and cutting tasks on metal surfaces in both shop and field environments. The Type 27 raised-hub design allows a low grinding angle, making it effective on flat stock, sheet metal, weld seams, and structural sections. It is sold individually and available in case quantities of 25 units, making it practical for stocking a service van or shop supply room. The NorZon Plus abrasive formulation is intended for consistent cut rate and extended wheel life under moderate load conditions.
