08N504 - Walter Pipefitter 5-Inch Grinding Wheel for Pipeline Root Pass

Specialized Abrasive for Pipeline Construction

The Walter Surface Technologies 08N504 Pipefitter™ grinding wheel is a highly specialized abrasive tool engineered specifically for the rigorous demands of the pipeline industry. Measuring 5 inches in diameter with a 7/8-inch arbor, this wheel features a unique 5/32-inch thickness. This specific dimension is critical for pipefitters, as it provides the ideal profile for grinding joint welds, notching, and performing root pass cleaning without removing excessive base material. The wheel is manufactured with a premium Aluminum Oxide (A-36) grain structure that delivers a consistent, aggressive cut rate while maintaining a long service life under heavy pressure.

One of the defining technical characteristics of the Pipefitter™ series is its chemical composition. It is formulated to be free of iron, sulfur, and chlorine (containing less than 0.1% of these elements), making it guaranteed safe for use on stainless steel and other high-performance alloys. This prevents cross-contamination that could lead to corrosion or weld defects in critical infrastructure. The wheel utilizes a reinforced resinoid bond that withstands the mechanical stresses typical of field applications, such as beveling and facing pipe ends. Rated for a maximum speed of 12,200 RPM, the 08N504 ensures stability and safety when paired with compatible 5-inch angle grinders.

In industrial MRO and construction settings, efficiency is paramount. The Walter Pipefitter wheel reduces downtime by combining the capabilities of light grinding and heavy cleaning into a single, durable disc. Its Type 27 depressed center geometry allows for comfortable grinding angles, ensuring operators can access tight joint configurations effectively. Whether used for preparing pipe ends or cleaning up weld beads between passes, this wheel represents the pinnacle of application-specific abrasive engineering.
