Tru-maxx 66243496730 Surface Grinding Wheel 46 Grit 10 in

Product Description

The TRU-MAXX 66243496730 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous workpieces. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The wheel is constructed from aluminum oxide abrasive grain bonded with a vitrified bond, producing a white, semi-friable wheel rated at a coarse 46 grit and I hardness. Maximum operating speed is 2483 RPM. This wheel is installed and used by machinists, tool grinders, and surface grind operators working on manual or CNC surface grinders.

This grinding wheel is suited for surface grinding applications in machine shops, tool rooms, and production grinding environments. Its coarse 46-grit rating makes it effective for aggressive material removal on steel, cast iron, and similar ferrous materials. The vitrified bond provides rigidity and consistent cutting action, making it a standard choice for flat surface work on horizontal or vertical spindle surface grinders that accept a 10-inch diameter, 3-inch bore Type 1 wheel.

Key Features

• Type 1 flat wheel profile with no recess — standard configuration for surface grinders
• 46 grit aluminum oxide abrasive for coarse, aggressive stock removal
• I hardness rating with grain structure 5 — soft-to-medium wheel that releases grain efficiently to prevent loading
• Vitrified bond provides rigidity and open cutting action for consistent surface finishes
• Semi-friable abrasive grain self-sharpens during use, extending wheel life between dressings
• Specification code 28A46I5V31 for cross-reference with equivalent wheel standards

Compatibility

Designed as a replacement-style Type 1 surface grinding wheel for horizontal or vertical spindle surface grinders that accept a 10-inch diameter wheel with a 3-inch arbor bore and a 1-inch face width.

Installation Notes

Grinding wheel installation must be performed by qualified personnel following ANSI B11.9 and OSHA 1910.215 wheel mounting requirements. Always ring-test the wheel before mounting and never exceed the rated maximum speed of 2483 RPM. Use proper flanges and blotters, and dress the wheel before first use to true the face and ensure concentric running. Power down and lock out the grinder before removing or installing any wheel.
