Norton 69014192067 Surface Grinding Wheel 4in 220 Grit

Product Description

The NORTON 69014192067 is a Type 1A1R diamond surface grinding wheel designed for precision surface grinding applications. Built with Armored Synthetic Diamond (ASD) abrasive and a metal bond, this wheel delivers consistent material removal on hard, brittle workpieces where conventional abrasives fall short. The 220 grit rating places it in the fine grade range, making it well-suited for finishing passes and tight-tolerance work. At 4 inches in diameter and just 0.020 inches thick, the wheel offers a narrow cutting profile that minimizes heat generation and reduces stress on delicate workpieces. It is installed and operated by machinists and tool grinders working on precision grinding equipment.

This wheel is intended for surface grinding operations in machine shops, toolrooms, and manufacturing environments. The Type 1A1R form factor is a standard straight wheel configuration commonly used on surface grinders and tool and cutter grinders. The fine 220 grit and 1/8 inch superabrasive depth make it appropriate for finishing operations on ceramics, carbide, hardened steels, and similar hard materials that require controlled stock removal and a refined surface finish.

Key Features

• 220 grit diamond abrasive for fine-grade surface finishing
• Armored Synthetic Diamond (ASD) superabrasive at 100 concentration for consistent cutting performance
• Metal bond construction provides durability and precise abrasive retention
• Type 1A1R straight wheel form fits standard surface and tool grinder spindles
• 1/8 inch superabrasive depth supports extended wheel life before redress
• Narrow 0.020 inch wheel thickness reduces lateral cutting forces and workpiece stress

Compatibility

Designed as an OEM-style replacement or direct fitment for surface grinders and tool and cutter grinders accepting a Type 1A1R straight wheel with a 4 inch diameter and 1/2 inch hole bore.

Installation Notes

Diamond grinding wheels of this type are mounted and operated by qualified machinists or tool grinders familiar with precision grinding equipment. Power down and lock out the grinder before mounting or removing the wheel. Verify that the spindle speed rating of the machine does not exceed the maximum operating speed marked on the wheel. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel.
