Norton 66253043887 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043887 is a Type 1 surface grinding wheel designed for precision flat-surface stock removal on ferrous and non-ferrous metals. Built around an aluminum oxide abrasive with a vitrified bond, this wheel runs at a maximum of 3600 RPM and operates at a medium grade with a G hardness code. The 32A series specification designates it for consistent cut rate and wheel life on a wide range of metalworking applications. At 8 inches in diameter, 1/2 inch thick, and with a 1-1/4 inch arbor hole, this wheel fits standard surface grinder spindles and is installed by tool-and-die makers, machinists, and maintenance professionals working in production or job-shop environments.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Material compatibility includes 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 60 grit rating positions it as a medium-cut wheel appropriate for material removal stages where surface finish is important but aggressive stock removal is still required. Its porous structure promotes coolant flow and chip clearance during extended grinding passes.

Key Features

• Aluminum oxide abrasive for reliable performance across ferrous and non-ferrous metals
• Vitrified bond provides rigidity and consistent cut rate with good wheel life
• 60 grit medium grade for balanced stock removal and surface finish quality
• G hardness code with porous structure supports coolant retention and chip evacuation
• Type 1 straight wheel profile with no recess fits standard surface grinder arbors
• Rated to 3600 RPM maximum for safe operation on compatible machines

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or toolroom professional following ANSI B7.1 safe-use guidelines for abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and ensure the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Use appropriate flanges and blotters as specified by the grinder manufacturer.
