Pro-source 5590005011PRO Cutoff Wheel 4 in Aluminum Oxide

Product Description

The PRO-SOURCE 5590005011PRO is a Type 1 flat cutoff wheel designed for use with angle grinders in metal cutting and fabrication applications. The wheel measures 4 inches in diameter and 0.05 inches thick, with a 16 mm arbor hole. The abrasive material is aluminum oxide, bonded with a resinoid bond that holds the grain matrix together under high rotational stress. This wheel is used by electricians, plumbers, pipefitters, HVAC technicians, and general fabricators who need a reliable thin-kerf cutoff wheel for ferrous metals, conduit, rod, and structural stock.

This cutoff wheel is suited for light to medium-duty cutting tasks on angle grinders in both residential and commercial trade environments. The 4-inch diameter fits compact angle grinders commonly used in tight spaces such as mechanical rooms, utility chases, and overhead installations. The thin 0.05-inch profile minimizes material loss at the cut and reduces heat buildup during operation. Typical applications include cutting threaded rod, EMT conduit, pipe, and metal strut channel.

Key Features

• 4-inch diameter fits standard compact angle grinders
• 0.05-inch thickness delivers a thin kerf cut with minimal material waste
• 16 mm arbor hole for compatibility with common angle grinder spindles
• Aluminum oxide abrasive for cutting ferrous metals and general-purpose metal stock
• Resinoid bond construction maintains wheel integrity under rotational load
• Type 1 flat wheel profile for straight cutoff operations

Compatibility

Designed for use with angle grinders accepting a 4-inch diameter Type 1 cutoff wheel with a 16 mm arbor hole.

Installation Notes

Installation and use of this wheel should be performed by a qualified trade professional familiar with angle grinder safety procedures. Always inspect the wheel for cracks or damage before mounting, and never exceed the maximum RPM rating printed on the wheel. Ensure the grinder is fully de-energized and unplugged before changing wheels. Use the appropriate guard and wear proper PPE including eye and face protection during all cutting operations.
