Norton 69014192212 Surface Grinding Wheel 7in 180 Grit

Product Description

The NORTON 69014192212 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications requiring a very fine finish. Built with Armored Synthetic Diamond (ASD) abrasive and a resinoid bond, this wheel operates under wet conditions to maintain workpiece integrity and extend wheel life. At 7 inches in diameter with a 1/2-inch thickness and 1-1/4-inch arbor hole, it carries a 180-grit rating and a soft hardness grade (R), making it well suited for controlled material removal and finish improvement on hard or brittle materials such as carbide, ceramics, and hardened tool steel.

This wheel is intended for use on surface grinders in tool rooms, production shops, and maintenance environments where tight tolerances and surface finish quality are priorities. The 1/4-inch superabrasive depth provides adequate wheel life for regular production use. It is typically installed and operated by machinists, toolroom technicians, and grinding specialists working with hard materials that conventional abrasive wheels cannot finish effectively. The ASD series designation indicates a concentration of 75, balancing cut rate with wheel longevity for general-purpose fine grinding work.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for grinding hard and brittle materials
• 180 grit, very fine grade for finish improvement and close-tolerance surface work
• Resinoid bond with soft hardness rating (R) for controlled, consistent cut action
• Wet operation design helps dissipate heat and flush grinding debris
• 1/4-inch superabrasive depth at 75 concentration for balanced life and cut rate
• Type 1A1 straight wheel profile with no recess, no taper for standard surface grinder mounting

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for surface grinders accepting a Type 1A1 straight wheel with a 7-inch diameter and 1-1/4-inch arbor hole.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting, and ensure the arbor, flanges, and blotters are clean and properly sized for a 1-1/4-inch bore. Ring-test the wheel prior to use per ANSI B7.1 safety requirements, and confirm the grinder's rated speed meets or exceeds the wheel's maximum operating speed before startup.
