Norton 66260273611 Diamond Surface Grinding Wheel 100 Grit

Product Description

The NORTON 66260273611 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications in industrial and trade shop environments. Built with synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent stock removal during roughing operations on hard or abrasive materials. It measures 6 inches in diameter and 1/8 inches thick with a 1-1/4 inches hole size, making it compatible with standard surface grinding spindles. The 100 grit rating and Fine grade designation produce controlled material removal suited to workpieces that require a balance between cut rate and surface finish. Wet operation is required for proper use. The wheel weighs approximately 1 pound.

This wheel is suited for surface grinding operations in toolrooms, production grinding, and maintenance shops. Type 1A1 straight wheels are commonly mounted on horizontal-spindle surface grinders. The 1/4 inches superabrasive depth supports sustained use across multiple dressings. With a concentration rating of 100 and a Soft hardness rating (R), this wheel is optimized for roughing passes on carbide, ceramics, glass, and other hard materials where conventional abrasives wear too quickly.

Key Features

• Synthetic diamond abrasive (SD) for grinding carbide, ceramics, and hard materials
• Resinoid bond provides controlled cut action and good finish for roughing operations
• 100 grit Fine grade balances material removal rate with surface quality
• Type 1A1 straight wheel geometry fits standard surface grinder spindles
• 1/4 inches superabrasive depth extends usable wheel life through multiple dressings
• Wet operation rating helps manage heat and prolong wheel and workpiece integrity

Compatibility

Designed for use on horizontal-spindle surface grinders accepting a 1-1/4 inches arbor hole and capable of mounting a 6 inches diameter Type 1A1 straight wheel. Wet grinding setup is required.

Installation Notes

Grinding wheel installation should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 and OSHA 1910.215 standards. Always inspect the wheel for cracks or damage before mounting and perform a ring test per manufacturer guidelines. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the maximum operating speed marked on the wheel, and always use the appropriate flanges and blotters for a secure, balanced mount.
