Norton 69014192188 Diamond Grinding Wheel 4in 320 Grit

Product Description

The NORTON 69014192188 is a Type 1A1 diamond surface grinding wheel designed for precision finishing on hard and brittle materials. Built with synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent stock removal and fine surface finishes at 320 grit. At 4 inches in diameter and 0.02 inches thick, it fits standard surface grinding spindles with a 1-1/4 inch hole. The 1/8 inch superabrasive depth and 100 concentration rating support extended wheel life in wet grinding operations. This wheel is intended for use by machinists, toolroom technicians, and trade professionals who require repeatable, extra fine finishing results.

This wheel is suited for surface grinding applications where tight tolerances and smooth surface finishes are required. Its extra fine 320 grit rating makes it appropriate for finishing passes on carbide tooling, ceramics, glass, and similar hard materials. Wet operation is specified, making it compatible with coolant-fed surface grinders commonly found in machine shops and toolroom environments. The resinoid bond provides a degree of compliance that helps reduce heat buildup during finishing cuts.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per standard abrasive wheel safety procedures. Ensure coolant flow is established before beginning wet grinding operations to prevent heat damage to the wheel bond and workpiece.
