Norton 66260273613 Surface Grinding Wheel 150 Grit 6in

Product Description

The NORTON 66260273613 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications in metalworking and industrial machining environments. Built with a synthetic diamond (SD) abrasive and resinoid bond, this wheel delivers consistent material removal and finishing performance at a very fine 150 grit grade. The wheel measures 6 inches in diameter and 1/8 inches thick, with a 1-1/4 inches arbor hole. It is rated for wet operation and carries a soft hardness rating (R-grade), making it well-suited for controlled stock removal and fine finishing passes. Licensed machinists, tool grinders, and industrial maintenance technicians are the primary installers and operators of this wheel.

This grinding wheel is intended for roughing and finishing operations on hard and brittle materials where diamond abrasive provides a clear performance advantage over conventional abrasives. The Type 1A1 straight-wheel geometry fits standard surface grinder spindles accepting a 1-1/4 inches arbor. With a 1/4 inches superabrasive depth and 100 concentration of synthetic diamond abrasive, the wheel is built for production-level consistency. It is part of the Norton Diamond series and suits applications in precision grinding shops, toolrooms, and industrial maintenance settings handling carbide, ceramic, glass, and similar hard materials.

Key Features

• Synthetic diamond (SD) abrasive at 100 concentration for consistent cutting performance
• 150 grit very fine grade for controlled stock removal and smooth surface finish
• Resinoid bond provides good shock resistance and self-dressing characteristics
• Soft hardness rating (R-code) reduces heat buildup and promotes free cutting action
• Rated for wet operation, compatible with standard water-soluble and oil-based grinding coolants
• Type 1A1 straight-wheel form with no recess and no taper for straightforward spindle mounting

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for surface grinders accepting a Type 1A1 straight wheel with a 1-1/4 inches arbor hole and a 6 inches diameter wheel capacity.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator following the grinder manufacturer's spindle speed and mounting specifications. Power down and lock out the grinder before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 standards. Never exceed the maximum RPM rating marked on the wheel, and always use appropriate coolant flow when operating in wet mode.
