Norton 66253466721 Centerless Grinding Wheel 16in 60 Grit

Product Description

The NORTON 66253466721 is a Type 1 centerless cylindrical grinding wheel designed for precision stock removal and finishing on cylindrical workpieces. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and stable performance across a range of centerless grinding operations. At 16 inches in diameter, 2 inches wide, with a 5-inch hole size, it fits standard centerless grinding machine spindles used in production and job-shop environments. The 60 grit medium grade makes it well suited for general-purpose grinding where moderate material removal and a reasonably smooth finish are both required. Rated at a maximum of 2030 RPM, it is intended for use by machining professionals and grinding specialists.

This wheel is a direct fit for centerless grinding applications in industrial and manufacturing settings. Its non-porous vitrified bond construction provides rigidity and chemical resistance, making it appropriate for wet or dry grinding operations on steel, ferrous alloys, and similar materials. The dark blue wheel color and 64A60-K8V127 specification code help simplify identification and reordering. It is typically installed on horizontal-spindle centerless grinding machines in production lines, tool rooms, and precision grinding shops.

Key Features

• Non-porous construction maintains wheel integrity under standard grinding pressures
• Specification code 64A60-K8V127 for straightforward identification and replacement ordering
• Maximum 2030 RPM rating matched to standard centerless grinding machine spindle speeds

Compatibility

Designed as an OEM-style replacement grinding wheel for horizontal-spindle centerless grinding machines that accept a 16-inch diameter, 2-inch wide, 5-inch hole Type 1 wheel configuration.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards for abrasive wheel machinery. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to installation. Power down and lock out the machine before changing wheels. Never exceed the 2030 RPM maximum speed rating marked on the wheel or its packaging.
