Norton 69014192211 Surface Grinding Wheel 100 Grit 7 in

Product Description

The NORTON 69014192211 is a Type 1A1 diamond surface grinding wheel designed for wet roughing operations on hard and superhard materials. Built with Armored Synthetic Diamond (ASD) abrasive at a 75 concentration level and bonded with a resinoid compound, this wheel delivers controlled stock removal with a fine, 100-grit cut. At 7 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, it mounts to standard surface grinders used in tool rooms, production grinding, and maintenance shops. The soft wheel hardness rating (R) supports consistent abrasive release during contact, helping to prevent glazing on the workpiece surface.

This wheel is suited for surface grinding applications where a diamond abrasive is required, such as grinding carbide tooling, ceramics, glass, or other superhard substrates. It is designed for wet operation, meaning coolant must be applied during use to manage heat and extend wheel life. The 1/4 inch superabrasive depth provides a meaningful service life for production and maintenance grinding tasks. Licensed grinding machine operators and tool-and-die professionals are the typical end users for this type of wheel.

Key Features

• Type 1A1 straight wheel geometry for surface and reciprocating grinder setups
• Armored Synthetic Diamond (ASD) abrasive at 75 concentration for consistent cut rate
• 100 grit, fine grade — suited for roughing passes requiring controlled material removal
• Resinoid bond with soft (R) hardness rating to maintain free cutting action
• Wet operation design — requires coolant for proper performance and wheel longevity
• 1/4 inch superabrasive depth provides extended usable wheel life

Compatibility

Designed for use on surface grinders accepting a Type 1A1 wheel with a 7 inch diameter, 1/2 inch thickness, and 1-1/4 inch arbor hole. Intended for wet grinding of hard and superhard materials including carbide, ceramics, and similar substrates.

Installation Notes

Installation and wheel changes must be performed by a qualified grinding machine operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips prior to mounting, and perform a ring test as required. Never exceed the maximum operating speed marked on the wheel, and ensure coolant lines are operational before beginning a wet grinding cycle.
