Norton 66253043725 Surface Grinding Wheel 60 Grit 8 in

Product Description

The NORTON 66253043725 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. It is built around an aluminum oxide abrasive grain bonded in a vitrified matrix, carrying a 60 grit medium-grade specification and an I hardness code. At 8 inches in diameter, 0.5 inches thick, and with a 1.25-inch arbor hole, this wheel is sized for standard surface and cylindrical grinding spindles. It is rated to 3600 RPM and conforms to the 32A60-IVBE specification. Licensed HVAC, metalworking, and industrial maintenance technicians install this wheel on surface grinders and CNC cutting tool machines where consistent, repeatable material removal is required.

This wheel is suited to both production and toolroom environments. It performs on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous vitrified bond promotes coolant flow through the wheel face, reducing heat buildup during prolonged cuts. Typical applications include surface grinding flat stock, sharpening tooling, and finish grinding machine components where flatness tolerance is critical.

Key Features

• Aluminum oxide abrasive grain — suitable for ferrous and non-ferrous material applications
• Vitrified bond with porous structure for improved coolant retention and heat dissipation
• 60 grit medium grade — balanced stock removal and surface finish
• I hardness code (32A60-IVBE specification) for consistent wheel life on production runs
• 3600 RPM maximum rated speed
• Type 1 straight wheel profile with no recess — direct mount on standard arbor flanges

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. Arbor bore of 1.25 inches fits standard grinding spindle configurations for this wheel diameter class.

Installation Notes

Grinding wheel installation should be performed by a qualified machinist or maintenance technician in accordance with ANSI B7.1 safety standards. Always perform a ring test before mounting and confirm the spindle RPM does not exceed the wheel's 3600 RPM maximum rating. Power down and lock out the machine before changing wheels, and inspect flanges for damage or debris before seating the wheel. Never force the wheel onto the arbor — the bore should slip on freely without modification.
