Tru-maxx T5-7W33918-T Surface Grinding Wheel 60 Grit

Product Description

The TRU-MAXX T5-7W33918-T is a Type 5 surface grinding wheel engineered for precision stock removal on surface grinders. Measuring 7 inches in diameter and 1 inch thick with a 1-1/4 inch arbor hole, this wheel uses aluminum oxide abrasive bonded in a vitrified matrix. The 60 grit size and I hardness rating place it in the medium-grade range, making it well suited for general-purpose surface grinding where consistent finish and controlled material removal are the priority. Rated to a maximum of 3600 RPM, it is installed and operated by machinists and toolroom professionals on horizontal-spindle surface grinders.

This wheel is appropriate for surface grinding operations on ferrous metals and general shop stock. The Type 5 recessed configuration, with a 2-3/4 inch recess diameter on one side, allows clearance for flanges and adapters on compatible surface grinder spindles. It performs at medium depth-of-cut passes typical in toolroom, maintenance, and production grinding environments where a balance of cutting action and wheel life is required.

Key Features

• Type 5 one-side recessed design with 2-3/4 inch recess diameter for flange clearance
• 60 grit aluminum oxide abrasive for medium-grade stock removal on ferrous materials
• Vitrified bond construction for consistent grain exposure and cool cutting action
• I hardness rating with semi-friable grain for controlled wheel breakdown and self-sharpening behavior
• Grain structure rating of 6 for a balanced, non-porous wheel face
• 3600 RPM maximum operating speed

Compatibility

Designed as a Type 5 recessed surface grinding wheel for use on horizontal-spindle surface grinders accepting a 1-1/4 inch arbor hole and a 7 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B7.1 safety standards, and ensure the machine spindle speed does not exceed the 3600 RPM rated maximum. Power down and lock out the grinder before changing wheels. Use proper flanges and a blotter between the flange and wheel face; never force the wheel onto the arbor.
