Norton 66252836394 Surface Grinding Wheel 60 Grit 6in

Product Description

The NORTON 66252836394 is a Type 1 straight surface grinding wheel designed for precision material removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 6 inches in diameter, 0.5 inches thick, with a 0.5-inch arbor hole. It carries a 60 grit, medium grade specification coded 32A60-KVBE, and is rated to a maximum of 4,140 RPM. The porous wheel structure promotes coolant flow and chip clearance during continuous stock removal. Licensed HVAC, machining, and tool-and-die professionals will find this wheel suited to flat surface grinding on a range of materials including steels, cast iron, and aluminum.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The Type 1 straight profile makes it a direct fit for standard wheel flanges on bench and pedestal surface grinding setups. It is appropriate for both production shop environments and precision toolroom applications where consistent grit performance and wheel integrity are required.

Key Features

• 60 grit medium grade for general-purpose stock removal and surface conditioning
• Porous wheel construction promotes chip clearance and reduces heat buildup
• Maximum rated speed of 4,140 RPM for safe use on compatible grinders
• Type 1 straight profile with no recess, fits standard arbor flanges
• Series specification 32A60-KVBE for verified material and bond identification

Compatibility

Rated 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

Installation should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safe use guidelines for abrasive wheels. Always inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the rated maximum RPM of 4,140. Ensure the machine is fully de-energized and locked out before changing wheels. Use properly rated flanges and a blotter on each side of the wheel during mounting to distribute clamping load evenly.
