11L408 - Walter ZIP 4-Inch Type 27 Cut-Off Wheel for Die Grinders

Premium Cutting Performance for Die Grinders

The Walter Surface Technologies 11L408 ZIP™ Wheel represents the pinnacle of performance in the category of small-diameter cutting abrasives. Designed specifically for professional industrial environments, this 4-inch cutting wheel is engineered to mount seamlessly onto straight shaft grinders and die grinders equipped with a 3/8-inch arbor. As part of the renowned ZIP™ family, this product is formulated to deliver the fastest, coolest, and freest cuts possible, ensuring that operators can work efficiently without compromising on safety or quality.

One of the defining characteristics of this wheel is its Type 27 depressed center configuration. Unlike standard flat (Type 1) wheels, the Type 27 shape provides added rigidity and allows the locking nut to be recessed. This design feature is critical when working in confined spaces or when flush cutting is required against a surface. Combined with an ultra-thin thickness of just 1/32 inch, the wheel removes minimal material, resulting in less friction, lower energy consumption, and significantly reduced heat generation. This makes it an exceptional choice for working with heat-sensitive materials.

Metallurgical integrity is paramount in modern fabrication. The Walter 11L408 is manufactured with a specialized bond that is free of iron, sulfur, and chlorine. This contaminant-free formulation ensures that the wheel will not cause corrosion or rust when used on stainless steel, making it safe for nuclear, food grade, and pharmaceutical applications. While it excels on stainless steel, it is equally effective on mild steel and other ferrous alloys, providing versatility across various projects.

Durability is a core component of the Walter ZIP™ series. Despite its thin profile, the wheel is heavily reinforced to withstand the high rotational speeds and lateral forces often encountered during notching and shaping operations. The proprietary grain blend self-sharpens as it wears, maintaining a consistent cutting rate throughout the life of the wheel. For MRO professionals and fabricators looking to maximize productivity with their die grinders, the 11L408 offers a superior balance of speed, life, and safety.
