Norton 66253043413 Surface Grinding Wheel 46 Grit 8 in

Product Description

The NORTON 66253043413 is a Type 1 surface grinding wheel designed for precision material removal on ferrous and non-ferrous metals in industrial grinding applications. Built from aluminum oxide abrasive with a vitrified bond, this wheel measures 8 inches in diameter, 1/4 inch thick, and carries a 1-1/4 inch arbor hole. The 46 grit, K hardness (coarse grade) specification makes it well suited for aggressive stock removal while maintaining consistent cut. It is rated to a maximum of 3600 RPM and carries the 32A46-KVBE specification designation. Installation and use are typically handled by machinist trades or grinding technicians in a shop environment.

This wheel is used in surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Confirmed material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It fits standard surface grinder and cylindrical grinder spindles with a 1-1/4 inch bore. The porous, vitrified structure promotes coolant flow and chip clearance during extended grinding passes, making it a reliable choice for both production and toolroom work.

Key Features

• Aluminum oxide abrasive for consistent performance on ferrous and non-ferrous materials
• Vitrified bond with porous structure promotes coolant flow and chip clearance
• 46 grit coarse grade suited for aggressive stock removal
• K hardness rating provides medium wheel hardness for balanced cut and wheel life
• Type 1 straight wheel profile fits standard surface grinder and cylindrical grinder spindles
• 32A46-KVBE specification designation for traceability and replacement accuracy

Compatibility

Confirmed 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. Fits spindles requiring a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding technician 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 cracks or chips before each use and perform a ring test per standard procedure. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
