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.
