Tru-maxx 66253269898 Surface Grinding Wheel 46 Grit 7in

Product Description

The TRU-MAXX 66253269898 is a Type 1 surface grinding wheel designed for precision stock removal on surface grinders in metalworking and fabrication environments. Built from aluminum oxide abrasive, it operates at a maximum speed of 3600 RPM and carries a 46 grit, coarse-grade cutting structure suited for aggressive material removal on ferrous metals. At 7 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, this wheel fits standard horizontal-spindle surface grinders. The G hardness code indicates a soft bond grade, which releases abrasive grains readily to maintain a free-cutting action across the work surface.

This wheel is intended for surface grinding applications in machine shops, tool rooms, and general metalworking operations. The porous structure promotes coolant flow and reduces heat buildup during extended grinding passes. Its ruby-colored aluminum oxide grain is well suited for general-purpose grinding on carbon steel, alloy steel, and similar ferrous workpieces. Machinists and tool grinders install this wheel on horizontal-spindle reciprocating surface grinders requiring a standard 1-1/4 inch bore.

Key Features

• Aluminum oxide abrasive grain for general-purpose ferrous metal grinding
• 46 grit coarse grade delivers aggressive stock removal
• G hardness (soft bond) promotes free-cutting action and reduced workpiece heat
• Porous wheel structure supports coolant flow and chip clearance
• Type 1 straight-wheel configuration for horizontal-spindle surface grinders
• 3600 RPM maximum operating speed

Compatibility

Designed as a standard Type 1 replacement grinding wheel for horizontal-spindle surface grinders accepting a 7 inch diameter, 1/2 inch thick wheel with a 1-1/4 inch arbor bore.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 safety standards. Always power down and lock out the grinder before mounting or removing wheels. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the marked maximum RPM of 3600. Use proper flanges and blotters as specified by the machine manufacturer.
