Norton 66260273566 Surface Grinding Wheel 120 Grit 7in

Product Description

The NORTON 66260273566 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications in industrial and trade environments. Built with a synthetic diamond (SD) abrasive and a resinoid bond, this wheel delivers consistent material removal at a fine 120 grit rating. It measures 7 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole, and weighs 1.5 pounds. The wheel carries a soft hardness rating (Code R) and a superabrasive concentration of 100, making it well suited for controlled roughing and cut-off work on hard, abrasive materials. Installation and operation are performed by skilled grinding machine operators in shop and production environments.

This wheel is intended for surface grinding operations where a fine finish and consistent stock removal are required. It is rated for both wet and dry operation, giving operators flexibility depending on coolant availability and workpiece requirements. The 0.25-inch superabrasive depth provides adequate grinding life for roughing and cut-off tasks. With no recess and no taper, it mounts flat and concentric on compatible surface grinding spindles. The Norton Diamond series is commonly found in tool rooms, production shops, and maintenance facilities working with hard materials such as ceramics, carbide, and hardened steel.

Key Features

• Synthetic diamond (SD) abrasive for effective grinding of hard, abrasive materials
• Resinoid bond provides controlled cut action and smooth finish at 120 grit fine grade
• Rated for both wet and dry operation for application flexibility
• Type 1A1 straight wheel geometry with no recess and no taper for flat, concentric mounting
• Superabrasive concentration of 100 for consistent, uniform material removal
• Soft wheel hardness (Code R) reduces glazing on demanding workpieces

Compatibility

Designed as an OEM-style replacement or direct-use grinding wheel for surface grinding machines accepting a 7-inch diameter, 1.25-inch arbor hole, Type 1A1 straight wheel configuration.

Installation Notes

Installation should be performed by a qualified grinding machine operator following the machine manufacturer's mounting instructions and all applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test where applicable. Do not exceed the maximum operating speed marked on the wheel or the machine, whichever is lower.
