Tru-maxx 66253269743 Surface Grinding Wheel 10in 46G

Product Description

The TRU-MAXX 66253269743 is a Type 1 surface grinding wheel designed for precision stock removal on surface grinders in metalworking and fabrication environments. Built with a ceramic abrasive grain and vitrified bond, this wheel delivers consistent cutting action and thermal stability under sustained grinding loads. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a 46 grit coarse grade with K hardness rating for aggressive material removal on ferrous metals. The non-porous vitrified structure maintains wheel integrity at speeds up to 3250 RPM. It is installed and dressed by machinists, tool grinders, and skilled trade professionals working on manual or CNC surface grinding equipment.

This wheel is suited for coarse-stock surface grinding applications in job shops, toolrooms, and production grinding operations. The coarse 46 grit and medium K hardness make it appropriate for rapid material removal on steel and similar ferrous workpieces where surface finish requirements are secondary to stock removal rate. The 3-inch bore accommodates standard surface grinder spindle arbors used in these applications. The blue ceramic grain formulation is commonly specified for general-purpose surface grinding where wheel life and free-cutting action are priorities.

Key Features

• Type 1 straight wheel profile for use on horizontal spindle surface grinders
• Ceramic abrasive grain with vitrified bond for consistent cut and thermal resistance
• 46 grit coarse grade for aggressive stock removal
• K hardness (medium) for balanced wheel wear and cutting efficiency
• 3250 RPM maximum rated speed
• Non-porous structure maintains dimensional stability during grinding

Compatibility

Designed as an OEM-style replacement or direct-use grinding wheel for horizontal spindle surface grinders accepting a 10-inch diameter, 1-inch wide, 3-inch bore Type 1 wheel.

Installation Notes

Surface grinding wheels must be installed by qualified machine operators or machinists following the wheel manufacturer and machine manufacturer mounting instructions. Always perform a ring test before mounting and inspect the wheel for cracks or damage. The machine spindle must be brought to a complete stop and locked out before wheel changes are made, in accordance with ANSI B11.4 and applicable OSHA standards. Never exceed the rated maximum RPM of 3250 and always use the appropriate flange and blotter assembly for this wheel size.
