08N904 - Walter PIPEFITTER 9-Inch Grinding Wheel Type 27

Engineered for Pipeline Integrity and Efficiency

The Walter PIPEFITTER™ (SKU: 08N904) is a specialized abrasive solution designed to meet the rigorous demands of the pipeline construction and fabrication industry. Measuring 9 inches in diameter with a 5/32-inch thickness and a standard 7/8-inch arbor, this Type 27 depressed center wheel is formulated to deliver optimal performance in joint weld grinding, facing, and beveling applications. Its unique composition addresses the critical needs of industrial pipe fabrication, balancing aggressive material removal with structural integrity.

A primary technical advantage of the PIPEFITTER™ series is its purity. The wheel is guaranteed to be free of iron, sulfur, and chlorine (Fe, S, Cl < 0.1%), making it an essential consumable for projects involving stainless steel and other high-performance alloys. This contaminant-free formulation prevents the introduction of impurities into the weld zone, thereby reducing the risk of corrosion and ensuring compliance with strict nuclear and food-grade industry standards. For procurement managers and safety officers, this certification simplifies inventory management by providing a single wheel capable of handling both carbon steel and stainless steel tasks without cross-contamination risks.

The A-20 grit specification indicates a coarse, aggressive aluminum oxide grain structure optimized for heavy stock removal. The 5/32-inch thickness is specifically engineered to fit into standard weld bevels and root passes, allowing operators to grind effectively without compromising the surrounding metal. Reinforced for safety at speeds up to 6,600 RPM, the Walter 08N904 offers extended wheel life and consistent performance, translating to reduced downtime for wheel changes and lower total cost of operation in high-volume fabrication environments.
