Tru-maxx 66253246701 Surface Grinding Wheel 60 Grit 7 in

Product Description

The TRU-MAXX 66253246701 is a Type 5 recessed surface grinding wheel designed for precision surface grinding applications on hard, brittle, and non-ferrous materials. Built with silicon carbide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a controlled finish at speeds up to 3600 RPM. At 7 inches in diameter and 3/4 inches thick with a 1-1/4 inch arbor hole, it fits standard surface grinder spindles. The I hardness code and medium grade make it well-suited for moderate material removal without excessive wheel breakdown. Weighing 2.86 pounds, it is a solid, single-piece wheel ready for direct mounting.

This wheel is intended for surface grinding operations in machine shops, tool rooms, and maintenance environments. The silicon carbide grain is particularly effective on cast iron, non-ferrous metals, ceramics, and other hard or brittle workpieces. The Type 5 form features a one-side recess measuring 3 inches in diameter and 1/4 inch deep, which reduces contact area and heat buildup during flat surface grinding passes. It is typically installed and operated by machinists and grinding technicians working with horizontal or vertical spindle surface grinders.

Key Features

• Silicon carbide abrasive with vitrified bond for consistent cut and controlled breakdown
• Type 5 one-side recessed wheel reduces heat and improves coolant access during surface grinding
• 60 grit, medium grade (Hardness Code I) suitable for moderate stock removal on hard and brittle materials
• Rated to 3600 RPM maximum operating speed
• Non-porous, green-colored wheel for visual identification of silicon carbide grain
• 1-1/4 inch arbor hole fits standard surface grinder spindle configurations

Compatibility

Designed as an OEM-style replacement or direct-use surface grinding wheel for horizontal and vertical spindle surface grinders accepting a 7 inch diameter, 1-1/4 inch hole, Type 5 wheel.

Installation Notes

Surface grinding wheels must be installed by qualified machinists or grinding technicians following all applicable 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 dismounting a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; do not mount a damaged wheel. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
