3M 7100313588 Cut and Grind Wheel 7 Inch 36+ Grit

Product Description

The 3M 7100313588 Cubitrona 3 Cut and Grind Wheel is a dual-purpose abrasive wheel engineered for both cutting and grinding operations on stainless steel and mild steel. It uses 3M Precision Shaped Ceramic Grain — a re-engineered mineral with sharp, angular structures that continuously fracture to expose fresh cutting edges, allowing the wheel to run cooler, wear more evenly, and cut faster with less applied pressure. At 7 inches in diameter and 1/8 inch thick, it fits standard angle grinders used in fabrication, maintenance, and field service work. Licensed tradespeople and skilled fabricators are the primary installers and users of this wheel.

This wheel is suited for cutting, grinding, and gouging on both stainless steel and mild steel substrates. Its 1/8 inch profile makes it versatile enough to function as a cut-off wheel in tight spaces or as a grinding wheel on flat and curved surfaces. Typical applications include structural steel fabrication, pipe cutting, weld cleanup, and general metal removal in shop and field environments. The reformulated wheel composition is designed to deliver better balance and smoother action compared to earlier Cubitrona II abrasives, helping reduce rework and improve surface finish quality.

Key Features

• Dual-purpose design functions as both a cut-off wheel and a grinding wheel for cutting, grinding, and gouging
• Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges throughout the wheel life
• Compatible with stainless steel and mild steel substrates
• Reformulated wheel composition delivers improved balance and smoother action versus Cubitrona II
• Rigid, reinforced, resin-bonded construction for consistent performance under load
• Designed for reduced time and pressure requirements compared to previous-generation wheels

Compatibility

Designed for use on stainless steel and mild steel substrates as a direct upgrade from 3M Cubitrona II Performance Abrasives; fits standard 7 inch angle grinder arbors typical in fabrication and maintenance applications.

Installation Notes

Wheel mounting and use should be performed by qualified personnel familiar with angle grinder safety practices. Always power down and unplug or lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or damage before each use and confirm the grinder speed rating meets or exceeds the wheel maximum RPM rating. Use appropriate PPE including face shield, gloves, and hearing protection during operation.
