Tru-maxx T1-12W31505-T Surface Grinding Wheel 46 Grit

Product Description

The TRU-MAXX T1-12W31505-T is a Type 1 surface grinding wheel designed for heavy-duty stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and thermal stability under sustained load. At 46 grit, the wheel falls in the coarse grade range, making it well-suited for aggressive material removal rather than finish work. Rated to a maximum of 2,069 RPM and weighing 9 pounds, this wheel is sized at 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. H hardness rating indicates a medium-soft bond that releases dull grains efficiently to maintain cut rate.

This wheel is intended for use on surface grinders in machine shops, tool rooms, and industrial maintenance environments. The 12-inch diameter and 3-inch hole fit standard horizontal spindle surface grinder configurations. Coarse 46-grit construction makes it appropriate for rapid stock removal on steel, cast iron, and similar hard materials where surface finish is a secondary concern to throughput. Licensed machinists and grinding specialists are the primary installers and operators of this wheel type.

Key Features

• Aluminum oxide abrasive construction for durability on ferrous metals
• Vitrified bond provides rigidity and thermal resistance during extended grinding cycles
• 46 grit coarse grade for aggressive stock removal
• H hardness semi-soft bond grade promotes self-dressing action to maintain sharpness
• No recess design for full-face grinding contact
• Semi-friable grain structure balances sharpness and grain longevity

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for horizontal spindle surface grinders accepting a 12-inch diameter, 3-inch arbor hole, Type 1 straight wheel configuration.

Installation Notes

Wheel mounting should be performed by a qualified operator following ANSI B11.22 and applicable OSHA grinding safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 2,069 RPM maximum rating stamped on the wheel. Use appropriate flanges and blotters as specified by the grinder manufacturer, and dress the wheel before first use to true the running surface.
