Tru-maxx RESIN-82 Diamond Cutoff Wheel Type 1A1R 8 in

Product Description

The TRU-MAXX RESIN-82 is a Type 1A1R diamond cutoff wheel designed for precision cutting of hard and brittle materials. Built with a resinoid bond and 120 grit diamond abrasive, this wheel delivers consistent, controlled cuts with minimal chipping. At 8 inches in diameter and 0.045 inches thick, the wheel is optimized for straight cutoff work on angle grinders. The 1/4-inch superabrasive depth and 100 concentration rating indicate a robust diamond layer that supports extended wheel life under demanding conditions. This wheel is suited for trade professionals and fabricators who require accurate, repeatable cuts on materials such as stone, ceramic, concrete, or similar hard substrates.

The RESIN-82 is intended for use with angle grinders fitted with a 5/8-inch arbor. Its Type 1A1R flat-profile geometry makes it appropriate for straight plunge and through cuts rather than contour or curve work. Typical applications include tile and stone fabrication, masonry cutting, and precision sectioning of hard materials in both shop and field environments. The resinoid bond is well suited to dry or wet cutting scenarios depending on grinder and workpiece requirements.

Key Features

• Diamond abrasive at 120 grit for precise, fine cutting action on hard materials
• Resinoid bond construction for consistent performance and controlled wear
• Type 1A1R flat wheel profile optimized for straight cutoff operations
• 1/4-inch superabrasive depth with 100 concentration for extended service life
• 5/8-inch arbor hole fits standard angle grinder spindles
• 0.045-inch blade thickness minimizes material loss and kerf width

Compatibility

Designed for use with angle grinders equipped with a 5/8-inch arbor and capable of accommodating an 8-inch diameter Type 1A1R cutoff wheel. Verify grinder RPM rating meets or exceeds the wheel's maximum rated speed before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always power down and disconnect the angle grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels, and ensure the grinder guard is properly positioned before operation.
