Tru-maxx 66253246690 Surface Grinding Wheel 7in 100 Grit

Product Description

The TRU-MAXX 66253246690 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on hard materials. Built from silicon carbide abrasive and bonded with a vitrified bond, this wheel delivers consistent cutting action across its full face. It measures 7 inches in diameter, 1/4 inch thick, and accepts a 1-1/4 inch arbor hole. The 100-grit, I-hardness rating places it in the fine grade, medium-hardness category — suited for controlled material removal where surface finish quality matters. Machinists, tool-and-die workers, and grinding specialists are the primary installers and users of this wheel.

This grinding wheel is intended for use on surface grinders in both job shop and production environments. The silicon carbide abrasive compound makes it well-suited for grinding non-ferrous metals, cast iron, carbide tooling, ceramics, and other hard or brittle materials. The green wheel color and non-porous structure are consistent with silicon carbide wheels used in precision grinding applications. It is sold individually and is appropriate for horizontal-spindle reciprocating-table surface grinders that accept a 7-inch diameter, Type 1 wheel.

Key Features

• Type 1 flat wheel profile — no recess, full-face grinding surface
• Silicon carbide abrasive for use on hard, brittle, and non-ferrous materials
• Vitrified bond provides rigidity and consistent grain exposure
• 100 grit, fine grade for controlled stock removal and improved surface finish
• I hardness code — medium hardness rating for balanced wheel life and cut rate
• 3600 RPM maximum operating speed

Compatibility

Designed as a direct-fit replacement or standard-use grinding wheel for surface grinders that accept a 7-inch diameter, Type 1 wheel with a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM of 3600. Proper flanges, blotters, and guards must be in place before operation.
