Norton 69014192170 Surface Grinding Wheel 120 Grit

Product Description

The NORTON 69014192170 is a Type 1A1R diamond surface grinding wheel engineered for precision flat grinding applications. Built with synthetic diamond abrasive and a resinoid bond, it delivers consistent stock removal and a controlled finish on hard, abrasion-resistant materials. The wheel measures 10 inches in diameter with a 0.05 inch thickness and a 1-1/4 inch arbor hole. It carries a 120 grit rating, a coarse grade designation, and a hardness code of R (soft wheel hardness rating). The superabrasive depth is 1/4 inch with a concentration of 100, conforming to specification SD120-R100B99-1/4. This wheel is installed and dressed by grinding professionals working with surface grinders in toolroom and production environments.

This wheel is suited for surface grinding operations on hard and brittle workpiece materials such as carbide, ceramics, glass, and hardened tool steels. It fits standard surface grinding spindles with a 1-1/4 inch bore. The thin 0.05 inch profile makes it appropriate for cutoff and slotting-style surface grinding tasks where minimal material kerf is required. Toolroom machinists and grinding specialists are the primary users in both job shop and production-floor settings.

Key Features

• Type 1A1R wheel geometry for flat and cutoff surface grinding
• Synthetic diamond abrasive for grinding carbide, ceramics, and hardened materials
• Resinoid bond provides controlled cut rate and consistent finish
• 120 grit coarse grade with hardness code R for aggressive stock removal
• Superabrasive concentration of 100 for uniform cutting performance across the wheel face
• 1/4 inch superabrasive depth for extended wheel life

Compatibility

Designed as an OEM-style replacement grinding wheel for surface grinders accepting a 1-1/4 inch arbor bore and a 10 inch diameter Type 1A1R wheel.

Installation Notes

Wheel mounting and dressing should be performed by a qualified grinding machine operator or toolroom machinist following the machine manufacturer guidelines and ANSI B7.1 safety standards. Always power down and lock out the surface grinder before mounting or removing a grinding wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per standard practice. Never exceed the maximum operating speed marked on the wheel.
