11L253 - Walter ZIP 2-Inch Type 1 Grinding Wheel for Die Grinders

Technical Overview of the Walter ZIP Die Grinder Wheel

The Walter 11L253 is a specialized abrasive wheel designed for high-speed straight shaft and die grinders. Part of the renowned ZIP™ family, this 2-inch diameter wheel is engineered to deliver exceptional material removal rates while maintaining structural integrity under the high RPMs typical of pneumatic and electric die grinders. With a thickness of 1/2 inch and a 3/8-inch arbor, it is configured as a Type 1 straight wheel, making it suitable for peripheral grinding applications.

The abrasive matrix is composed of a proprietary blend of grain and bond, graded as A-24-ZIP. This formulation is specifically developed to resist glazing, a common issue in small diameter wheels where heat buildup can be intense. The porous structure allows for continuous exposure of fresh abrasive grains, ensuring that the wheel cuts aggressively throughout its lifespan. Crucially for industrial MRO applications, the bond is free of iron, sulfur, and chlorine, making it safe for use on stainless steel without risk of cross-contamination or corrosion induction.

Vibration control is a critical aspect of die grinder consumables. Walter manufactures these wheels with strict concentricity tolerances to minimize runout. This results in reduced operator fatigue and prevents chatter marks on the workpiece. The reinforced construction adds a layer of safety, allowing the wheel to withstand the lateral forces often encountered during notching and shaping operations in confined spaces. It is rated for a maximum speed of 30,600 RPM, aligning with standard industrial die grinder specifications.

This wheel is an optimal solution for fabrication shops requiring precision stock removal in areas where 4.5-inch or 5-inch angle grinders cannot reach. It bridges the gap between mounted points and larger grinding wheels, offering the durability of a bonded wheel with the maneuverability of a die grinder accessory.
