Norton 66253464837 Grinding Wheel 16in Aluminum Oxide 60 Grit

Product Description

The NORTON 66253464837 is a Type 1 centerless cylindrical grinding wheel engineered for precision stock removal and finish grinding on cylindrical workpieces. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action across a wide range of ferrous metals and tool steels. At 16 inches in diameter, 1 inch wide, and with a 5-inch arbor hole, it fits standard centerless grinder spindles used in production and job shop environments. The 60-grit medium grade designation and K-hardness rating make it well suited for general-purpose cylindrical grinding where moderate material removal and surface finish are both priorities. Weighing 10.66 pounds, it is handled and mounted by skilled grinding machine operators or toolroom machinists.

This wheel is designed for use on centerless cylindrical grinding machines in industrial, production, and toolroom settings. It is appropriate for through-feed and in-feed centerless grinding operations on bar stock, shafts, pins, and similar round workpieces. The aluminum oxide grain with vitrified bond performs reliably on carbon steel, alloy steel, and similar ferrous materials. Its non-porous structure and grain structure rating of 5 contribute to stable wheel geometry throughout the grind cycle. The specification code 32A60-K5VBE identifies the exact wheel formulation for sourcing and replacement reference.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cutting action on ferrous metals
• 60-grit medium grade provides a balance of stock removal rate and surface finish quality
• K-hardness (medium) rating supports broad applicability across general cylindrical grinding tasks
• Non-porous wheel construction maintains dimensional stability and resists loading
• Rated to 2030 RPM maximum for safe operation on compatible centerless grinders
• Gray wheel color and no-recess design simplify identification and standard flange mounting

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for centerless cylindrical grinding machines accepting a 16-inch diameter, 1-inch wide, Type 1 wheel with a 5-inch arbor hole. Specification code 32A60-K5VBE confirms formulation compatibility when cross-referencing existing wheel orders.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or damage before mounting and perform a ring test. Power down and lock out the grinding machine completely before changing wheels. Never exceed the rated maximum of 2030 RPM and always use properly sized flanges and blotters as required by the grinder manufacturer.
