08C452 - Walter Allsteel 4-1/2" x 1/8" Type 27 Grinding Wheel for Steel & Stainless

High-Performance Abrasive for Industrial Fabrication

The Walter Allsteel™ Type 27 Grinding Wheel (SKU: 08C452) is a premium abrasive solution designed to meet the rigorous demands of industrial metalworking. Engineered by Walter Surface Technologies, this 4-1/2 inch wheel features a thickness of 1/8 inch and a standard 7/8 inch arbor, making it compatible with most professional angle grinders. The Allsteel™ series is specifically formulated to deliver exceptional performance on both carbon steel and stainless steel, providing a versatile option for maintenance, repair, and operations (MRO) environments where material variety is common.

One of the standout features of the 08C452 is its ability to deliver cool, fast, and free cutting. Unlike lower-quality abrasives that may glaze over or generate excessive heat, the Allsteel™ matrix ensures consistent grain exposure. This results in a high removal rate without compromising the structural integrity of the workpiece through heat stress. The 1/8-inch thickness is particularly advantageous for applications requiring more precision than a standard 1/4-inch wheel, such as cleaning root passes, light beveling, or working in tighter spaces where control is paramount.

Safety and durability are core components of the Walter design philosophy. This wheel is reinforced to resist bending and twisting, significantly reducing the risk of wheel breakage during aggressive grinding. Furthermore, the formulation is free of iron, sulfur, and chlorine (Fe-S-Cl free), ensuring that it will not contaminate stainless steel surfaces, which is critical for nuclear, food grade, or pharmaceutical applications. For industrial procurement managers and fabricators, the Walter Allsteel™ represents a cost-effective, high-efficiency choice that streamlines inventory by performing equally well on multiple metal types.
