08N503 - Walter PIPEFITTER 5-Inch x 3/32-Inch Type 27 Grinding Wheel

Technical Overview: Walter PIPEFITTER Grinding Wheel

The Walter PIPEFITTER™ (SKU: 08N503) is a specialized abrasive product engineered specifically for the rigorous demands of the pipeline industry. This 5-inch grinding wheel features a nominal thickness of 3/32 inches, a dimension critically selected to facilitate effective root pass grinding. The wheel utilizes a Type 27 depressed center configuration, which is standard for providing the necessary clearance for the operator's hands and the angle grinder locking nut during operation in tight bevels.

Manufactured with a proprietary grain blend, the PIPEFITTER wheel is designed to remove material rapidly while maintaining a cool cutting action. This is essential in pipe fabrication to prevent heat accumulation that could alter the metallurgical properties of the base metal. The wheel is reinforced to withstand the lateral forces often applied during the grinding of root beads and joint welds. Its composition is free of iron, sulfur, and chlorine (Fe-free), making it fully compatible with both carbon steel and stainless steel applications, ensuring no cross-contamination occurs during the grinding process.

The 3/32-inch thickness places this wheel in a unique category, bridging the gap between standard 1/4-inch grinding wheels and thin cut-off wheels. This hybrid thickness allows for the structural integrity required for light grinding and facing, while being thin enough to access the narrow root of a weld joint. It is rated for a maximum speed of 12,200 RPM and features a standard 7/8-inch arbor, making it compatible with most industrial 5-inch angle grinders.
