Tru-maxx RESIN-73 Diamond Cutoff Wheel 6 in Type 1A1R 220 Grit

Product Description

The TRU-MAXX RESIN-73 is a Type 1A1R diamond cutoff wheel designed for precision cutting applications on hard and brittle materials. It measures 6 inches in diameter with a 0.035-inch thickness and a 1-1/4-inch arbor hole, fitting standard angle grinder spindles. The abrasive material is diamond at 220 grit, bonded with a resinoid bond and rated at 100 concentration. A superabrasive depth of 1/4 inch provides cutting life suited to demanding trade work. Machinists, fabricators, and tool-and-die technicians are the typical installers and operators for this type of wheel.

This wheel is intended for use with angle grinders in applications that require fine, controlled cuts on hard materials such as ceramics, stone, glass, carbide, and similar substrates. The 220 grit rating makes it appropriate for finish-quality cutting rather than aggressive stock removal. It is sold individually and suits both shop and field use where a 6-inch angle grinder is the tool of choice. Hardness code N indicates a medium-hard bond suited to a range of workpiece hardness levels.

Key Features

• Type 1A1R straight profile optimized for cutoff operations on angle grinders
• Diamond abrasive at 220 grit for clean, finish-quality cuts on hard materials
• Resinoid bond with 100 concentration for consistent abrasive exposure throughout wheel life
• 1/4-inch superabrasive depth delivers extended cutting life per wheel
• 0.035-inch kerf minimizes material loss during precision cuts
• Hardness code N provides a medium-hard bond suitable for a broad range of substrate hardness

Compatibility

Designed for use with angle grinders accepting a 6-inch diameter, 1-1/4-inch arbor hole cutoff wheel in the Type 1A1R profile.

Installation Notes

This wheel must be mounted and operated by personnel familiar with abrasive wheel safety per ANSI B7.1 and the grinder manufacturer guidelines. Always inspect the wheel for cracks or damage before mounting and confirm the grinder RPM rating meets or exceeds the wheel RPM rating before operation. Power down and disconnect the grinder from its power source before changing wheels. Never use a blotter, adapter flange, or mounting hardware not rated for this arbor size.
