Norton 662529-40098 Type 27 Grinding Wheel 7x1/4x7/8

Product Description

The NORTON 662529-40098 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with Gemini aluminum oxide abrasive, it delivers consistent cut rates and extended wheel life across a wide range of ferrous metal applications. The wheel measures 7 inches in diameter, 1/4 inch thick, and accepts a 7/8 inch arbor bore, fitting standard angle grinders used throughout fabrication and construction trades. Rated to a maximum of 8600 RPM, it is suited for heavy-duty grinding tasks where both speed and control are required. Metalworkers, pipefitters, ironworkers, and welding professionals rely on this wheel for weld bead removal, surface conditioning, and edge preparation.

This grinding wheel is intended for use on metal substrates in both shop and field environments. The Type 27 depressed center profile allows the operator to maintain a low grinding angle while keeping the tool body clear of the workpiece, making it well suited for flat surface grinding and weld flush work. It is appropriate for professional tradespeople performing fabrication, structural steel work, pipe fitting, and general metal grinding tasks in residential, commercial, and industrial settings.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never exceed the rated maximum RPM. Ensure the guard is properly installed and that all mounting flanges and hardware are clean and undamaged before operation.
