Norton 69014192192 Surface Grinding Wheel 4in 100 Grit

Product Description

The NORTON 69014192192 is a Type 1A1 diamond surface grinding wheel designed for precision surface grinding applications. It measures 4 inches in diameter and 1/32 inches thick, with a 1-1/4 inch arbor hole. The wheel uses synthetic diamond (SD) abrasive bonded with a resinoid bond system and carries a 100-grit fine grade rating with a hardness code of R (soft). The superabrasive depth is 1/4 inches and the concentration is 100. This wheel is rated for wet operation and is suited for roughing material removal. It is part of the Norton Diamond series and is installed by machinists and tool grinders working with hard or brittle materials.

This wheel is intended for surface grinding machines that accept a Type 1A1 straight wheel profile with a 1-1/4 inch bore. It is suited for wet-operation surface grinders in production or toolroom environments handling hard materials such as carbide, ceramics, glass, and hardened steels. The fine 100-grit grade makes it appropriate for roughing passes where controlled stock removal is required. The resinoid bond provides good shock resistance during grinding contact.

Key Features

• Type 1A1 straight wheel profile with no recess and no taper
• Synthetic diamond (SD) abrasive at 100 concentration for consistent cut rate
• Resinoid bond offers shock resistance and self-dressing characteristics
• 100-grit fine grade rated for roughing material application
• Rated for wet operation — compatible with water-soluble and oil-based coolants
• Soft hardness rating (R) reduces heat buildup on hard, brittle workpieces

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for surface grinders accepting a Type 1A1 straight wheel with a 4 inch diameter, 1/32 inch face width, and 1-1/4 inch arbor bore.

Installation Notes

Surface grinding wheels must be mounted by a qualified machinist or grinding machine operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI guidelines. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the wheel's rated maximum RPM. Use appropriate flanges and blotters as specified by the machine manufacturer.
