Norton 69014192099 Diamond Surface Grinding Wheel 6in 100G

Product Description

The NORTON 69014192099 is a Type 1A1R diamond surface grinding wheel designed for precision flat grinding applications. The wheel measures 6 inches in diameter and 0.055 inches thick, with a 1-1/4 inch arbor hole for secure mounting on compatible surface grinders. It carries 100-grit armored synthetic diamond (ASD) abrasive bonded in a metal bond matrix at a concentration of 75, rated Coarse grade with a Medium hardness code of N. The 1/8 inch superabrasive depth provides extended wheel life on hard, brittle materials. This wheel is intended for use by machining professionals, toolroom technicians, and skilled tradespeople requiring consistent, flat stock removal.

This wheel is suited for surface grinding of hard and superhard materials including carbide, ceramite, glass, and hardened tool steels. The metal bond construction and armored synthetic diamond abrasive make it appropriate for wet or controlled-coolant grinding environments where aggressive cut rates and long dress intervals are required. The Type 1A1R form factor is a standard straight wheel configuration commonly used on horizontal-spindle surface grinders in industrial and toolroom settings. Specification code M4D100-N75M99-1/8 identifies the full bond and concentration parameters for procurement and replacement matching.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for grinding carbide and hard ceramics
• Metal bond matrix for durability and extended wheel life in wet grinding applications
• 100 grit, Coarse grade for efficient stock removal on hard materials
• Superabrasive concentration of 75 with 1/8 inch abrasive depth for long service life
• Type 1A1R straight wheel form factor fits standard horizontal-spindle surface grinders
• Medium hardness (N) balances free cutting action with wheel integrity

Compatibility

Designed as an OEM-style replacement or direct-fit diamond grinding wheel for horizontal-spindle surface grinders accepting a 6 inch diameter, 1-1/4 inch arbor hole, Type 1A1R straight wheel.

Installation Notes

Diamond grinding wheels must be mounted and dressed by a qualified machinist or toolroom technician. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before installation and never exceed the maximum operating speed marked on the wheel. Use appropriate flanges and blotters as specified by the machine manufacturer, and confirm wheel balance before running at full speed.
