Tru-maxx 66253255895 Surface Grinding Wheel 60 Grit 7 in

Product Description

The TRU-MAXX 66253255895 is a Type 1 surface grinding wheel designed for precision flat-surface grinding on ferrous metals and general shop applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal with controlled wear. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and carries a 60 grit rating for medium material removal. The I hardness code and grain structure 6 classification make it well-suited for moderate grinding pressure across a range of workpiece materials. Rated at 3,600 RPM maximum, this wheel is intended for use by machinists, tool and die professionals, and maintenance trades operating surface grinders in job shop or production environments.

This wheel is used primarily on horizontal-spindle surface grinders in both job shop and light production settings. The Type 1 straight-wheel profile fits standard surface grinder spindle configurations. The 60 grit aluminum oxide composition handles general-purpose ferrous grinding, including mild steel, carbon steel, and similar materials where a medium finish and controlled material removal rate are required. The white aluminum oxide composition and semi-friable grain make it a practical choice for heat-sensitive applications where minimizing workpiece burn is a priority.

Key Features

• Type 1 straight wheel profile fits standard horizontal-spindle surface grinders
• Aluminum oxide abrasive with vitrified bond for consistent cut rate and wheel longevity
• 60 grit medium stock removal suitable for ferrous metals and general shop use
• I hardness code with grain structure 6 for controlled wear under moderate grinding pressure
• Semi-friable grain resists glazing and helps reduce workpiece heat buildup
• Non-porous, no-recess construction for straightforward mounting and balanced operation

Compatibility

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

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or maintenance technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Before mounting, inspect the wheel for cracks or chips using the ring test. Power down and de-energize the grinder before changing wheels, and ensure the arbor flange, blotter, and nut are clean and properly seated. Never exceed the 3,600 RPM maximum speed rating marked on this wheel.
