11L433 - Walter ZIP 4-Inch Die Grinder Wheel Type 1

High-Performance Abrasives for Precision Fabrication

The Walter 11L433 ZIP™ Grinding Wheel is a premium abrasive solution designed specifically for straight shaft and die grinders. In industrial environments where precision and accessibility are paramount, this 4-inch wheel offers a superior balance of material removal speed and wheel longevity. Engineered with Walter's proprietary grain blend, the ZIP™ wheel maintains a consistent cut rate throughout its life, ensuring that production schedules are met without frequent wheel changes. The 1/4-inch thickness is optimized for structural grinding, heavy deburring, and notching applications, providing the rigidity required for aggressive stock removal.

One of the critical technical advantages of the 11L433 is its cool-cutting formulation. Heat generation is a primary concern when working with heat-sensitive alloys like stainless steel, as it can lead to warping, discoloration, or metallurgical changes. This wheel is designed to dissipate heat effectively, preserving the integrity of the workpiece. Furthermore, it is manufactured to be free of iron, sulfur, and chlorine (Fe, S, Cl < 0.1%), making it guaranteed safe for use on stainless steel in contamination-sensitive industries such as food processing, pharmaceutical, and nuclear energy sectors.

For procurement and operations managers, the value proposition of the Walter ZIP™ wheel lies in its total cost of ownership. While providing the aggressive bite needed for tough steel, it resists glazing and premature wear, translating to fewer wheels used per shift and reduced downtime for changeovers. Its compatibility with standard 3/8-inch arbor die grinders makes it a versatile addition to any tool crib, ready to tackle tasks that are too intricate for large angle grinders but require more power than a standard burr.

Technical Specifications and Application

The wheel features a Type 1 straight profile, ideal for perpendicular grinding and getting into channels or corners. The 3/8-inch arbor ensures a secure fit on pneumatic and electric die grinders. Operators will appreciate the balanced construction which minimizes vibration, reducing the risk of Hand-Arm Vibration Syndrome (HAVS) during prolonged use. Whether used for preparing weld joints, leveling welds in confined spaces, or shaping metal parts, the 11L433 delivers consistent, industrial-grade performance.
