Product Description

The NORTON 66252837842 is a 14-inch diameter Type 1 resinoid-bonded aluminum oxide cut-off wheel built for demanding masonry and concrete cutting applications. At 1/8 inch thick with a 1-inch arbor hole, this wheel is reinforced with two layers of fiberglass mesh for added durability and operator safety during high-stress cuts. It is rated to a maximum of 5,400 RPM and is designed for use with angle grinders and compatible die grinders. Licensed contractors, masons, and concrete trade professionals are the primary installers and operators of this wheel in both field and shop settings.

This cut-off wheel is intended for cutting masonry materials including concrete, block, and similar hard construction substrates. The Gemini Concrete specification designation indicates it meets Norton's performance standard for concrete cutting.
