Norton 662530-07014 Type 27 Grinding Wheel 9x1/4x5/8-11

Product Description

The NORTON 662530-07014 is a Type 27 depressed center grinding wheel built for demanding foundry applications. Part of the NorZon Plus line, it uses an engineered abrasive grain construction designed to remove material aggressively on ferrous and non-ferrous metals. The wheel measures 9 inches in diameter with a 1/4-inch thickness and a 5/8-11 threaded arbor bore, fitting standard large-angle grinders. Maximum operating speed is rated at 6600 RPM. This wheel is sized and rated for production-level metal grinding where consistent stock removal and wheel life are priorities.

This grinding wheel is intended for foundry environments where cast metal, flash removal, weld grinding, and surface cleanup are routine tasks. Type 27 depressed center wheels provide a lower grinding angle that suits flat and beveled surface work on large castings, structural steel, and weld joints. The 9-inch diameter and 1/4-inch thickness make it appropriate for heavy-duty angle grinders used in industrial and commercial settings. Licensed metalworkers, foundry technicians, and fabrication professionals are the primary users of this wheel configuration.

Installation Notes

Mounting and removal of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Always power down and disconnect the grinder before changing wheels, and confirm the grinder's rated RPM meets or exceeds the wheel's maximum RPM before installation. Inspect the wheel for cracks or chips before mounting and never exceed the 6600 RPM maximum. Proper guard installation and appropriate personal protective equipment are required during operation.
