Norton 662529-38854 Type 27 Grinding Cutting Wheel 7in 8600 Rpm

Product Description

The NORTON 662529-38854 is a Type 27 depressed center abrasive wheel engineered for light grinding and cutting applications across metal fabrication, welding prep, and general maintenance work. The wheel measures 7 inches in diameter with a 1/8-inch thickness and a 7/8-11 threaded arbor connection, making it compatible with standard large-angle grinders. Rated at 8600 RPM, it delivers consistent stock removal at controlled speeds suited to thin-material work where aggressive material removal would cause distortion or damage. Each unit weighs 0.6 pounds.

This wheel is suited for trade professionals including pipefitters, ironworkers, welders, and maintenance mechanics who require a reliable depressed center wheel for light-duty grinding and cut-off tasks. The Type 27 profile — with its recessed center — allows flush grinding along flat surfaces and tight weld joints. The 7-inch diameter provides reach and surface coverage that smaller wheels cannot match, making it practical for structural steel, pipe, and sheet metal work on the job site or in the shop.

Installation Notes

Mounting and removal of abrasive wheels must be performed by a qualified operator following ANSI B7.1 safe use standards and the grinder manufacturer's guidelines. Power down and unplug or lockout the grinder before mounting or changing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated RPM.
