Tru-maxx 66253255219 6 in 60 Grit Silicon Carbide Grinding Wheel

Product Description

The TRU-MAXX 66253255219 is a Type 1 bench and pedestal grinding wheel designed for sharpening carbide tooling, non-ferrous metals, stone, and other hard, non-metallic materials. It is constructed from green silicon carbide abrasive with a vitrified bond, offering consistent stock removal and a semi-friable grain that breaks down to expose fresh cutting edges during use. The wheel measures 6 inches in diameter, 1 inch thick, with a 1-inch arbor hole, and weighs 2.24 pounds. It is rated to a maximum of 5,410 RPM and carries a 60-grit, medium-grade K-hardness specification (GC60K6V51). Electricians, machinists, and maintenance technicians typically use this wheel on standard bench or pedestal grinders.

This wheel is suited for bench and pedestal grinder applications in maintenance, repair, and operations (MRO) environments, machine shops, and trade service shops. The 60-grit medium grade makes it appropriate for general-purpose material removal on carbide tool faces, ceramic, glass, and similar hard non-ferrous workpieces. The 1-inch arbor hole fits standard bench grinder spindles. No bushing is included, so verify spindle diameter before mounting. Grain structure is rated at 6 with a non-porous, semi-friable composition that maintains wheel integrity under sustained load.

Key Features

• Green silicon carbide abrasive — suited for carbide, non-ferrous metals, ceramics, and stone
• Vitrified bond construction for rigid, consistent cutting action
• 60-grit medium grade (K hardness) for general stock removal
• 5,410 maximum RPM rating — verify grinder nameplate before mounting
• Semi-friable grain structure (rating 6) continuously exposes fresh abrasive during use
• Non-porous wheel body reduces loading when grinding soft or ductile non-ferrous materials

Compatibility

Designed for use on standard bench and pedestal grinders with a 1-inch arbor spindle. No reducing bushing is included; confirm spindle size matches the 1-inch hole diameter before installation.

Installation Notes

Grinding wheel installation should be performed by a qualified technician following ANSI B7.1 safety standards. Disconnect and lock out power to the grinder before removing the existing wheel or mounting this one. Inspect the wheel for cracks or chips before mounting — do not use a damaged wheel. After installation, run the grinder at operating speed for at least one minute with guards in place and no workpiece contact before beginning work.
