Radiac Abrasives 34078769 Surface Grinding Wheel 46 Grit

Product Description

The RADIAC ABRASIVES 34078769 is a Type 1 straight surface grinding wheel designed for precision stock removal on ferrous metals and similar hard materials. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and thermal stability under sustained grinding loads. The wheel carries a coarse 46 grit rating and a G hardness code, placing it in the soft-to-medium hardness range. This combination promotes free cutting and self-dressing behavior, making it well suited for surface grinder applications where heat control and material removal rate both matter. Installation and dressing are handled by qualified grinding machine operators or tool and die professionals.

This wheel is intended for use on horizontal-spindle surface grinders in light industrial, tool room, and maintenance shop environments. The 7 inch diameter and 1/2 inch thickness suit standard bench and reciprocating surface grinder setups. The 1-1/4 inch arbor hole fits common spindle configurations found in those machine classes. It is appropriate for general-purpose surface grinding of steel and similar materials where a coarse, free-cutting wheel is the correct choice for the operation.

Key Features

• Type 1 straight wheel profile with no recess for straightforward surface grinder mounting
• Aluminum oxide abrasive grain rated friable for consistent self-dressing and cooler cutting
• Vitrified bond provides rigidity and porosity retention through the wheel life
• 46 grit coarse grade for aggressive stock removal applications
• G hardness code (soft rating) supports free cutting action and reduces glazing
• 3600 RPM maximum operating speed clearly marked for safe machine setup

Compatibility

Designed as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders accepting a 7 inch diameter, 1/2 inch thick, Type 1 wheel with a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel mounting and dressing must be performed by trained personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 requirements. Always ring-test the wheel before mounting and inspect for cracks or chips. Never exceed the 3600 RPM maximum operating speed marked on the wheel. Power down and lock out the grinder fully before changing wheels or performing any maintenance.
