Norton 66253319941 Surface Grinding Wheel 46 Grit 14in

Product Description

The NORTON 66253319941 is a Type 5 surface grinding wheel designed for precision stock removal on ferrous metals using surface and cylindrical grinders. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action suited to hard carbon steels, soft carbon steels, and tool steels. It runs at a maximum of 2320 RPM and is rated for wet operation. At 14 inches in diameter and 2 inches thick with a 5-inch arbor hole, it is a large-format wheel intended for heavy-duty industrial grinding applications. The specification code is 48A46-HVP2.

This wheel fits surface grinders and cylindrical grinders handling hard carbon steels, soft carbon steels, and tool steels. Its coarse 46 grit rating and H hardness code make it appropriate for aggressive material removal rather than fine finishing work. The ruby-colored aluminum oxide grain and porous structure help dissipate heat during wet grinding operations, reducing thermal stress on the workpiece. It is well suited to production grinding environments where consistent cut rate and wheel life are priorities.

Key Features

• Aluminum oxide abrasive with vitrified bond for durable, consistent cutting performance
• 46 grit coarse grade for aggressive stock removal on ferrous metals
• H hardness (soft wheel hardness rating) helps the wheel self-dress on harder materials
• Porous structure supports wet operation and assists with heat and swarf evacuation
• One-side recess: 8-inch recess diameter, 0.5-inch recess depth for proper mounting clearance
• Specification code 48A46-HVP2 for exact replacement or cross-reference ordering

Compatibility

Designed for use with surface grinders and cylindrical grinders. Rated for hard carbon steels, soft carbon steels, and tool steels as stated in manufacturer specifications. Verify arbor size, machine speed rating, and flange requirements before mounting.

Installation Notes

Grinding wheel installation must be performed by a qualified operator following ANSI B11.9 and applicable shop safety standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 2320 RPM maximum speed rating. Use proper blotters, flanges, and guards as required by the machine manufacturer and OSHA 29 CFR 1910.215.
