08N454 - Walter Pipefitter 4.5-Inch Grinding Wheel A-36

Engineered for Pipeline Fabrication

The Walter Pipefitter™ 4-1/2" Grinding Wheel (08N454) is a specialized abrasive solution developed specifically for the demanding environment of pipeline construction and pipe fabrication. Unlike standard metal grinding wheels, the Pipefitter series is engineered with a unique 5/32-inch thickness. This profile is critical for pipe welders, as it provides a middle ground between a cutting wheel and a heavy-duty grinding disc, allowing for precise control when grinding joint welds, cleaning root passes, or performing intermittent light grinding tasks.

Contaminant-Free Performance

In high-stakes industries such as oil and gas, nuclear, or food processing, cross-contamination is a major concern. The Walter Pipefitter wheel is manufactured to be free of Iron, Sulfur, and Chlorine (Fe, S, Cl). This ensures that when used on stainless steel piping, the abrasive will not introduce impurities that could lead to corrosion or weld failure. It is a dual-purpose wheel that performs exceptionally well on both mild steel and stainless steel, reducing the need to swap wheels for different materials.

Structural Integrity and Safety

Pipeline work often involves awkward angles and high stress on the abrasive. These wheels are heavily reinforced to withstand the lateral forces applied during notching and facing operations. The A-36 grit formulation offers an aggressive bite for rapid stock removal while maintaining a cool cut to prevent heat discoloration on the workpiece. Whether you are bevelling a pipe end for fit-up or cleaning out a slag inclusion in a root pass, the 08N454 delivers consistent, safe, and reliable performance.

Technical Specifications

This wheel features a standard 7/8" arbor hole, making it compatible with most industrial 4-1/2" angle grinders. With a maximum RPM rating of 13,300, it is built to keep up with high-performance power tools used in the field.
