Tru-maxx 66253255261 Grinding Wheel 8in Silicon Carbide 80G

Product Description

The TRU-MAXX 66253255261 is a Type 1 bench and pedestal grinding wheel designed for sharpening, deburring, and material removal on hard metals and carbide tooling. Built with green silicon carbide abrasive and a vitrified bond, this wheel delivers consistent, free-cutting action suited for ferrous and non-ferrous work. It measures 8 inches in diameter, 3/4 inches thick, and carries a 1-1/4 inches arbor hole. The medium-grade, 80-grit spec and K-hardness rating make it appropriate for general-purpose tool and cutter work on bench grinders operated by machinists, tool room technicians, and maintenance trades.

This wheel is intended for use on stationary bench grinders and pedestal grinders in shop, tool room, and maintenance environments. The green silicon carbide composition is particularly well suited for grinding cemented carbides, non-ferrous metals, cast iron, and similar hard or brittle materials. The vitrified bond provides structural rigidity and consistent stock removal throughout the wheel life. This wheel is supplied without a bushing, so reducer bushings may be needed depending on the machine spindle size.

Key Features

• 8 inches diameter, 3/4 inches thick with 1-1/4 inches arbor hole for standard bench and pedestal grinder fitment
• Green silicon carbide abrasive rated semi-friable for efficient cutting on hard and brittle materials
• 80 grit, medium grade (K hardness) for general-purpose sharpening and light stock removal
• Vitrified bond construction provides rigidity and consistent performance throughout wheel life
• Non-porous, grain structure 6 for uniform abrasive density
• Rated to 3600 maximum RPM — verify machine nameplate does not exceed this rating before mounting

Compatibility

Designed for use on standard bench grinders and pedestal grinders with a 1-1/4 inches arbor. No bushing is included; reducer bushings are required for machines with smaller spindle diameters.

Installation Notes

Grinding wheel installation must be performed by qualified personnel following ANSI B7.1 safety standards. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips using a ring test before installation, and never mount a damaged wheel. Confirm the machine operating RPM does not exceed the 3600 RPM rating marked on this wheel.
