Norton 69014192086 Diamond Grinding Wheel 6 in 150 Grit

Product Description

The NORTON 69014192086 is a Type 1A1R diamond surface grinding wheel designed for precision flat grinding applications. Built with Armored Synthetic Diamond (ASD) abrasive and a metal bond, it delivers consistent stock removal and wheel life on hard, brittle materials. The wheel measures 6 inches in diameter with a 0.025-inch thickness and a 1-1/4-inch arbor hole. It carries a 150 grit rating at medium grade with a hardness code of N and a superabrasive concentration of 100. The 1/8-inch diamond depth provides a substantial working layer for extended use. This wheel is used by grinding machine operators and tool-and-die technicians working on surface grinders requiring tight tolerances.

This wheel is suited for surface grinding operations on ceramics, carbides, hardened steels, glass, and other hard or brittle workpiece materials. The Type 1A1R form factor is a standard configuration for reciprocating and rotary surface grinders. It fits spindles with a 1-1/4-inch bore and is appropriate for both production and toolroom environments where finish consistency and dimensional accuracy are required. The M4D150-N100M99-1/8 specification code identifies the full bond, grit, hardness, concentration, and depth parameters for procurement and replacement reference.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for high hardness material removal
• Metal bond construction for controlled wear and shape retention
• 150 grit medium grade for a balance of cut rate and surface finish
• Superabrasive concentration of 100 for consistent diamond distribution
• 1/8-inch superabrasive depth for extended wheel service life
• Type 1A1R form compatible with standard surface grinder spindles

Compatibility

Designed for use on surface grinders accepting a 6-inch diameter, 1-1/4-inch arbor hole Type 1A1R wheel. Verify spindle speed rating against the wheel's maximum operating RPM before mounting.

Installation Notes

Mounting and dressing of diamond grinding wheels should be performed by qualified machine operators or toolroom technicians following machine manufacturer guidelines and ANSI B7 safety standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or damage before mounting and use the correct flanges and blotters as specified for the arbor size. Never exceed the maximum operating speed marked on the wheel.
