Norton 66252838075 Surface Grinding Wheel 6in 14 Grit

Product Description

The NORTON 66252838075 is a Type 1 surface grinding wheel engineered for aggressive material removal on hard ferrous and non-ferrous metals. Built with a zirconia alumina abrasive and a resinoid bond, it delivers fast, consistent stock removal at a coarse 14 grit. The wheel measures 6 inches in diameter, 1 inch thick, and accepts a 5/8-inch arbor hole, making it a standard fit for bench and surface grinders in the 6-inch class. Rated to 8000 RPM and carrying a hard wheel hardness grade (code Q), it maintains form under heavy feed pressure. Specification designation NZ III 14-Q confirms abrasive type, hardness, and grit for procurement and replacement purposes. Weight is 1 pound.

This wheel is suited for rough grinding, weld cleanup, edge dressing, and heavy stock removal operations in metalworking shops, fabrication facilities, and maintenance environments. Its coarse 14-grit construction makes it appropriate for rapid material removal passes rather than finish grinding. Licensed machinists, tool-and-die techs, welding fabricators, and maintenance professionals working with steel, cast iron, and similar hard metals are the primary installers and end users of this wheel type.

Key Features

• Zirconia alumina abrasive for high-performance, fast-cutting action on tough metals
• Coarse 14 grit optimized for aggressive stock removal and weld cleanup
• Resinoid bond provides durability and resistance under heavy grinding loads
• Hard hardness grade (Q) maintains wheel integrity under sustained feed pressure
• Non-porous, no-recess Type 1 flat wheel construction — straightforward mounting
• 8000 RPM maximum speed rating for standard 6-inch bench and surface grinders

Compatibility

Designed as an OEM-style replacement for Type 1 flat surface grinding wheels used on standard 6-inch bench grinders and surface grinding machines accepting a 5/8-inch arbor.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for visible cracks or chips before installation, and perform a ring test per ANSI B7.1 procedures. Do not exceed the 8000 RPM maximum speed rating under any operating conditions.
