Norton 66252942833 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252942833 is a Type 5 surface grinding wheel engineered for demanding material removal on ferrous and non-ferrous metals. Built on a vitrified bond with aluminum oxide abrasive, this wheel measures 7 inches in diameter and 1-1/4 inches thick, with a 1-1/4 inch arbor hole and a one-side recess 5/8 inch deep and 2-3/4 inches in diameter. The 46 grit, H hardness (coarse grade) construction delivers aggressive stock removal while maintaining a controlled cut. Rated at a maximum of 3600 RPM, it is designed for wet operation and carries the 32A46-HVBE specification designation. Machinists and grinding technicians use this wheel on cylindrical and surface grinders in production and toolroom environments.

This wheel is suited for surface and cylindrical grinding applications across a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit rating makes it appropriate for aggressive roughing passes and high-volume material removal rather than fine finishing work. It is a porous, gray-colored wheel without taper, built to the 32A Type 5 series standard. Trade machinists and tool grinders working in job shops, manufacturing facilities, or maintenance departments will find this wheel a direct fit for standard surface grinder setups requiring a recessed wheel profile.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cutting action
• Type 5 recessed profile: one-side recess 5/8 inch deep, 2-3/4 inch recess diameter
• 46 grit coarse grade for aggressive stock removal on ferrous and non-ferrous metals
• Wet operation rated for use with grinding coolant or fluid
• H hardness code with porous structure to assist chip clearance and heat dissipation
• 32A46-HVBE specification for precise grade, bond, and structure identification

Compatibility

Designed for use with cylindrical grinders and surface grinders. 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 technician. Before mounting, power down and lock out the grinder in accordance with applicable OSHA lockout/tagout procedures. Inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the 3600 RPM maximum speed rating stamped on the wheel. Ensure flanges, blotters, and arbor hardware are clean and correctly sized for a 1-1/4 inch arbor hole before tightening.
