The 3M Cubitron 3 7100303966/90003 Depressed Center Grinding Wheel, 36+, T27, 4-1/2 in x 1/4 in x 7/8 in is a high-performance Type 27 grinding wheel engineered for aggressive material removal, delivering fast cut rates and extended wheel life on metal fabrication and industrial grinding tasks. Featuring 3M’s latest precision shaped ceramic grain technology, this depressed center grinding wheel cuts cooler, wears more evenly, and maintains consistent sharpness, making it ideal for carbon steel and stainless steel grinding, weld removal, beveling, and edge preparation while supporting safer, more controlled operation. This design helps workers stay productive and protected by reducing grinding pressure, minimizing heat buildup, and lowering operator fatigue compared to previous Cubitron generations, resulting in smoother finishes and fewer wheel changes on demanding jobs. Tested and manufactured to meet applicable ANSI safety standards for bonded abrasive wheels and designed to support OSHA-compliant work practices, this next-generation Cubitron 3 wheel outperforms earlier designs by maximizing precision shaped grain efficiency for superior cut speed, durability, and control in critical industrial applications. Available in 1 Each or in a Pack of 10.

The 3M Cubitron 3 7100303966 / 90003 Depressed Center Grinding Wheel is engineered for professionals who demand fast material removal, consistent performance, and longer wheel life when grinding metal. Built with 3M’s latest precision-shaped ceramic grain technology, this 36+ grit Type 27 grinding wheel cuts aggressively while requiring less pressure, helping reduce operator fatigue and improve control during extended grinding tasks. With a 4-1/2 inch diameter, 1/4 inch thickness, and standard 7/8 inch arbor, it fits most angle grinders commonly used in fabrication shops, job sites, and maintenance operations. Buyers often ask whether Cubitron 3 wheels are suitable for stainless steel and carbon steel, and the answer is yes—this wheel is designed to deliver cooler cutting and consistent results across a wide range of ferrous metals. Another common question is how long the wheel lasts compared to conventional grinding wheels; the precision-shaped grain continuously fractures to expose sharp cutting edges, which helps maintain cut rate and extend usable life. Safety-conscious users will also appreciate that this wheel is manufactured to meet ANSI B7.1 standards when used properly. Whether you’re grinding welds, preparing edges, or performing heavy stock removal, this high-performance grinding wheel supports productivity while maintaining predictable results. Enviro Safety Products, a trusted and experienced supplier of certified PPE and industrial safety solutions, offers this wheel to ensure professionals have access to reliable, job-ready abrasives backed by knowledgeable service and industry expertise.
