3M 7100303857 Cutoff Wheel 4 Inch Ceramic Type 1

Product Description

The 3M 7100303857 is a reinforced ceramic abrasive cutoff wheel designed for use with right angle grinders in metal fabrication and maintenance applications. The wheel measures 4 inches in diameter and 0.035 inches thick with a 3/8-inch round arbor hole. Built on a resinoid bond with ceramic grain rated at 60+ grit, it is engineered for fast, controlled cutting on rod, pipe, and gate or flash material. The Type 1 flat profile keeps the cutting path straight and predictable. Licensed trades and fabrication shops rely on this wheel for repetitive cutoff tasks where consistent grain exposure and wheel integrity matter.

This cutoff wheel is rated for right angle grinders and suits residential and commercial metal fabrication, mechanical contracting, and maintenance repair operations. Typical applications include pipe cutting, rod cutting, gate removal, and flash removal on ferrous and compatible metal workpieces. The ceramic abrasive construction supports sustained cutting performance across production-volume tasks. It is sold individually but requires a minimum order quantity of 50 units, making it appropriate for shop stock and fleet tool supply.

Key Features

• Ceramic abrasive grain at 60+ grit for aggressive, consistent material removal
• Reinforced construction with resinoid bond for structural integrity at speed
• Type 1 flat wheel profile delivers straight, accurate cutoff geometry
• Rated to 21,000 RPM maximum for compatibility with standard right angle grinders
• 3/8-inch round arbor hole fits common right angle grinder spindle sizes
• Suited for pipe cutting, rod cutting, gate removal, and flash removal

Compatibility

Designed for use with right angle grinders. Verify that the grinder spindle accepts a 3/8-inch arbor and that the tool is rated for operation at or below 21,000 RPM before mounting this wheel.

Installation Notes

Mounting and use of abrasive cutoff wheels should follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Power down and disconnect the grinder before installing or removing the wheel. Inspect the wheel for cracks or damage before each use and do not use a wheel that has been dropped or shows visible defects. Always use the appropriate guard and personal protective equipment, including eye and face protection, when operating a cutoff wheel.
