11W423 - Walter Allsteel 4-Inch Type 1 Cut-Off Wheel for Die Grinders

High-Performance Abrasive Technology

The Walter Allsteel™ 11W423 Cut-Off Wheel represents a pinnacle in bonded abrasive technology, specifically engineered for precision cutting applications using straight shaft and die grinders. Manufactured with premium aluminum oxide grains, this wheel is designed to withstand the high RPMs and unique stresses associated with smaller handheld grinding tools. The bonding matrix is carefully formulated to release fresh grain at an optimal rate, ensuring a consistent cut throughout the life of the wheel while maintaining structural integrity. This balance of durability and friability allows for rapid material removal without excessive operator pressure.

Optimized for Die Grinders

Unlike standard angle grinder wheels, the 11W423 features a 4-inch diameter paired with a 3/8-inch arbor hole, making it directly compatible with a wide range of pneumatic and electric die grinders. The Type 1 (flat) profile is essential for these tools, allowing operators to perform perpendicular cuts, slotting, and notching in tight spaces where larger 4.5-inch or 5-inch angle grinders cannot reach. The 1/8-inch thickness provides the necessary rigidity for stable cutting, reducing wheel deflection and ensuring straight, accurate cuts in various metal profiles.

Contaminant-Free for Stainless Steel

A critical feature of the Allsteel™ line is its chemical purity. This wheel is guaranteed to be free of Iron (Fe), Sulfur (S), and Chlorine (Cl), making it an ideal choice for the nuclear, food processing, and pharmaceutical industries where stainless steel integrity is paramount. Using a contaminant-free abrasive prevents the introduction of impurities that could lead to galvanic corrosion or rust spots on the finished workpiece. This dual-capability—performing equally well on mild steel and stainless steel—simplifies inventory management for industrial facilities.

Safety and Efficiency

Walter Surface Technologies prioritizes safety in every abrasive product. The 11W423 is reinforced to resist breakage and maintain stability at high rotational speeds. Its cool-cutting action minimizes heat buildup, which preserves the metallurgical properties of the base material and reduces the likelihood of heat discoloration or warping. For MRO professionals and industrial fabricators seeking a reliable, high-speed cutting solution for small-diameter applications, the Walter Allsteel 11W423 delivers proven performance.
