08N502 - Walter Pipefitter 5-Inch Grinding Wheel 1/8-Thick A-36

Specialized Abrasive for Pipeline Fabrication

The Walter Surface Technologies Pipefitter™ Grinding Wheel (SKU: 08N502) is a premium abrasive solution meticulously engineered for the demanding environment of pipeline construction and pipe fabrication. Measuring 5 inches in diameter with a precise 1/8-inch thickness and a standard 7/8-inch arbor, this wheel is designed to fit most professional angle grinders used in the field. The wheel features an A-36 grit formulation, which provides an optimal balance between aggressive stock removal and surface finish control, making it exceptionally effective for grinding joint welds between passes.

One of the critical advantages of the Pipefitter series is its chemical purity. These wheels are manufactured to be free of iron, sulfur, and chlorine (Fe, S, Cl < 0.1%), ensuring they will not contaminate stainless steel or other corrosion-resistant alloys. This feature is vital for projects in the nuclear, food processing, and energy sectors where material integrity is paramount. The reinforced structure of the wheel ensures safety and stability during operation, reducing vibration and operator fatigue.

The 1/8-inch thickness is specifically chosen for its versatility in "J" bevel cleaning and root pass grinding. Unlike thicker 1/4-inch wheels that are designed for heavy stock removal, the Pipefitter wheel allows for more precise control when facing lands or notching weld beads. It offers a cool cutting action that minimizes heat buildup, preserving the metallurgical properties of the base metal. Whether working on mild steel or high-grade stainless piping, the Walter 08N502 delivers consistent, reliable performance that professionals trust to maintain weld quality and efficiency on the job site.
