08B460 - Walter HP 4-1/2" x 1/4" Type 27 Grinding Wheel, 7/8" Arbor, A24 Grit

High-Performance Abrasive for Industrial Applications

The Walter HP Grinding Wheel (SKU: 08B460) is engineered to meet the rigorous demands of industrial metal fabrication. Designed for use with 4-1/2" angle grinders, this Type 27 depressed center wheel measures 4-1/2" in diameter with a 1/4" thickness and a standard 7/8" arbor hole. It is formulated to deliver high stock removal rates while maintaining a long service life, optimizing both productivity and consumable costs in professional environments.

Manufactured in Italy, the HP (High Performance) series utilizes a specialized bonding matrix and high-quality grain structure, typically A24 grit, to ensure consistent performance across various materials. While primarily targeted at steel applications, manufacturer specifications indicate versatility for use on stainless steel and aluminum as well. This flexibility allows facilities to consolidate inventory for general-purpose grinding tasks without sacrificing performance on specific substrates.

Safety and operator comfort are paramount in the design of Walter abrasives. The HP wheel is constructed to resist wear and maintain its structural integrity under heavy loads, reducing vibration and the physical effort required by the operator. This results in cleaner welds, faster prep times, and reduced fatigue during extended shifts. The 7/8" unthreaded arbor ensures compatibility with a wide range of standard backing flanges and locking nuts found on industrial angle grinders.

This product is sold in packages of 25, making it an ideal procurement choice for high-volume workshops. Whether used for heavy deburring, shaping, or grinding down welds, the Walter 08B460 provides the reliability and speed required for modern manufacturing and MRO operations.
