11W152 - Allsteel 5-Inch Type 27 Cut-Off Wheel for Steel and Stainless

Technical Overview of the Walter Allsteel 11W152

The Walter Allsteel™ 11W152 is a premium-grade Type 27 cut-off wheel engineered for versatility and safety in industrial environments. Designed with a depressed center, this 5-inch wheel allows operators to perform flush cutting operations without the interference of the mounting nut, a critical feature for structural fabrication and finishing work. The wheel features a thickness of 3/64 inches (.045"), which reduces friction and heat generation, preserving the metallurgical integrity of the workpiece.

Manufactured with a specialized aluminum oxide grain matrix, the Allsteel series is formulated to deliver consistent performance across both carbon steel and stainless steel applications. Crucially, the bonding agent is free of iron, sulfur, and chlorine (Fe, S, Cl < 0.1%), ensuring that the wheel will not introduce contaminants that could lead to corrosion or pitting on stainless steel surfaces. This makes it an ideal choice for nuclear, food processing, and pharmaceutical plant fabrication where material purity is paramount.

The 11W152 is reinforced to withstand the lateral stresses occasionally encountered during off-hand cutting, although it is strictly designed for cutting applications. It carries OSA certification, attesting to its compliance with rigorous international safety standards. With a maximum speed rating of 12,200 RPM, it is compatible with standard 5-inch angle grinders utilizing a 7/8-inch arbor. The A-30-S grade bond offers a hard, durable structure that resists premature wear while maintaining a sharp cutting edge throughout the wheel's life.
