11F172 - Walter ZIP Stainless 7-Inch Type 27 Cut-Off Wheel

Precision Cutting for Critical Stainless Applications

The Walter Surface Technologies ZIP Stainless™ 7-inch cut-off wheel (SKU: 11F172) represents the pinnacle of abrasive engineering for sensitive alloys. Designed with a Type 27 depressed center, this wheel offers superior rigidity and the ability to perform flush cuts without compromising the structural integrity of the disc. The 11F172 is manufactured using a specialized bonding matrix that is guaranteed to be free of Iron (Fe), Sulfur (S), and Chlorine (Cl), with trace elements measuring less than 0.1%. This chemical purity is critical for industries such as nuclear energy, food and beverage processing, and pharmaceutical manufacturing, where cross-contamination can lead to catastrophic corrosion or compliance failures.

Measuring 7 inches in diameter with a 1/16-inch thickness and a 7/8-inch arbor, this wheel is optimized for use on standard angle grinders. The A-46-SS grit formulation ensures a balance between aggressive material removal and a high-quality finish. Unlike standard aluminum oxide wheels that may generate excessive heat, the ZIP Stainless™ runs significantly cooler. This thermal management is achieved through a porous grain structure and advanced bonding agents that prevent glazing. By reducing the heat affected zone (HAZ), the wheel minimizes the risk of carbide precipitation and heat tinting, thereby reducing the need for secondary passivation or pickling processes.

Durability is a hallmark of the Walter ZIP family. The 11F172 features heavy-duty reinforcement layers that resist twisting and bending forces, providing a stable cutting path even under load. This stability translates to straighter cuts and extended wheel life, lowering the total cost of operation for industrial fabrication shops. Whether cutting heavy-wall stainless pipe, structural tubing, or sheet metal, this wheel delivers consistent performance that meets the rigorous demands of MRO and fabrication professionals.
