Tru-maxx 66253255244 Grinding Wheel 12in 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253255244 is a Type 1 bench and pedestal grinding wheel engineered for heavy stock removal and general-purpose tool grinding. Built with aluminum oxide abrasive in a vitrified bond, this wheel delivers consistent cut rate and controlled wear across a range of steel and ferrous metal applications. The wheel measures 12 inches in diameter, 1 inch thick, with a 1-1/4 inch hole diameter and carries a 60-grit medium-grade specification — spec code 27A60P5V13. At a rated maximum of 2,705 RPM, it is sized for large bench and pedestal grinders found in production shops, maintenance facilities, and trade workspaces. Weight is 11.37 pounds.

This grinding wheel is suited for tool and cutter grinding, workpiece shaping, and edge restoration on ferrous metals. The 60-grit medium grade balances material removal speed with surface finish, making it appropriate for general maintenance grinding and production sharpening tasks. It is typically installed and used by machinists, tool-and-die workers, maintenance technicians, and metalworking tradespeople operating bench or pedestal grinder stands. The non-porous, semi-friable grain structure supports consistent performance during extended grinding sessions without rapid glazing.

Compatibility

Designed for use on bench and pedestal grinders that accept a 12-inch diameter, 1-inch wide Type 1 wheel with a 1-1/4 inch arbor hole. No bushing is included; verify spindle diameter before installation.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Perform a ring test on the new wheel before mounting to check for cracks, and never exceed the maximum RPM marked on the wheel. Use proper flanges and blotters as required by grinder manufacturer specifications.
