3M 7100139226 Ceramic Cutoff Wheel 4.5 in Angle Grinder

Product Description

The 3M 7100139226 is a ceramic abrasive cutoff wheel designed for use with angle grinders in metal fabrication and maintenance applications. It measures 4.5 inches in diameter and 0.4 inches thick, with a 7/8 inch arbor hole that fits standard angle grinder spindles. The resinoid bond holds the ceramic abrasive grain firmly during high-speed cutting, with a maximum rated speed of 13,300 RPM. The reinforced construction resists breakage under lateral load. This wheel is suited for trade professionals performing cutting tasks on ferrous and non-ferrous metal stock in shop or field conditions.

This cutoff wheel is used for straight cutting on steel and stainless steel. Typical applications include cutting pipe, rod, angle iron, sheet metal, and structural steel during fabrication, installation, or repair work. The 4.5 inch diameter is compatible with small and mid-size angle grinders commonly used by pipefitters, ironworkers, plumbers, and HVAC technicians for field cutting tasks. The black resinoid-bonded ceramic wheel provides consistent cut depth and edge quality on both mild steel and stainless steel workpieces.

Key Features

• Ceramic abrasive material for cutting steel and stainless steel
• Resinoid bond type for secure grain retention at high RPM
• Reinforced construction reduces risk of wheel fracture during use
• Maximum speed rating of 13,300 RPM for compatibility with standard angle grinders
• 7/8 inch arbor hole fits most standard angle grinder spindles
• Thin 0.4 inch profile minimizes material loss per cut

Compatibility

Designed for use with angle grinders. Rated for cutting steel and stainless steel applications.

Installation Notes

This wheel is installed and used by trade professionals including pipefitters, HVAC technicians, plumbers, and metalworkers. Before mounting, verify that the angle grinder's no-load RPM does not exceed the 13,300 RPM wheel rating. Inspect the wheel for cracks or chips before each use and never use a damaged wheel. Ensure the arbor nut is tightened securely and the guard is in place before operating the grinder.
