Norton 66260273617 Surface Grinding Wheel 150 Grit 6 in

Product Description

The NORTON 66260273617 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding operations. It measures 6 inches in diameter, 0.125 inches thick, with a 1-1/4 inch bore, and carries a 150-grit very fine grade rating. The abrasive material is Armored Synthetic Diamond (ASD) bonded in a resinoid matrix, giving it consistent cut and extended wheel life under both wet and dry operating conditions. This wheel is suited for roughing and finishing passes on hard or brittle workpiece materials. Machinists, tool grinders, and grinding equipment operators are the primary users of this style of wheel.

This wheel is rated for wet and dry use, making it adaptable to surface grinders equipped with or without coolant systems. The Type 1A1 straight-wheel form fits standard surface grinding spindles with a 1-1/4 inch arbor bore. With a specification code of ASD150-R75B99-1/4, this wheel carries an ASD abrasive, 75 concentration, resinoid bond, and a 1/4 inch superabrasive depth. It is appropriate for roughing and finishing applications on carbide, ceramics, glass, and other hard materials commonly encountered in tool rooms and precision grinding shops.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for cutting hard and brittle materials
• 150 grit very fine grade for refined surface finishes on final or near-final passes
• Resinoid bond provides controlled cut rate and good finish quality
• Compatible with both wet and dry grinding operations
• 1/4 inch superabrasive depth for extended usable wheel life
• Soft hardness rating (code R) reduces loading on fine, hard workpiece materials

Compatibility

Designed as a Type 1A1 straight surface grinding wheel for use on surface grinders with a 1-1/4 inch arbor bore and a 6 inch wheel capacity. Specification code ASD150-R75B99-1/4 is part of the Norton ASD series.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified machine operator or toolroom technician following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Always inspect the wheel for cracks or chips before mounting and perform a ring test per applicable standards. Power down and lock out the grinder before mounting or removing the wheel. Do not exceed the wheel speed rating marked on the wheel or its packaging.
