11L251 - Walter ZIP 2-Inch Die Grinder Wheel Type 1

High-Performance Grinding for Confined Spaces

The Walter ZIP Grinding Wheel (11L251) is a premium abrasive solution designed specifically for straight shaft and die grinders. Measuring 2 inches in diameter with a substantial 1/2-inch thickness, this Type 1 wheel is engineered to tackle demanding grinding, shaping, and notching applications in areas where full-sized angle grinders cannot reach. Its compact size combined with Walter's proprietary abrasive technology makes it an indispensable tool for metal fabricators, pipefitters, and maintenance professionals.

Cool Cutting Technology

One of the standout features of the ZIP family is its ability to cut freely and coolly. This wheel is formulated with high-quality abrasive grains and a specialized bond that resists glazing and heat buildup. This is particularly critical when working with stainless steel and other heat-sensitive alloys, as it prevents bluing and thermal discoloration, eliminating the need for time-consuming rework or passivation.

Contaminant-Free Formulation

Safety and quality control are paramount in industrial welding. The 11L251 is manufactured to be contaminant-free, containing less than 0.1% of Iron (Fe), Sulfur (S), and Chlorine (Cl). This makes it safe for use on stainless steel, food-grade equipment, and nuclear plant applications where cross-contamination must be strictly avoided.

Durability and Balance

Despite its small stature, this wheel delivers aggressive stock removal and exceptional life. The 1/2-inch width provides stability during side grinding and notching tasks. Furthermore, Walter wheels are known for their superior balance, which significantly reduces vibration. Less vibration means greater operator comfort, reduced risk of hand-arm vibration syndrome (HAVS), and a smoother finish on the workpiece.

Application Versatility

Equipped with a 5/16-inch arbor, this wheel fits standard mandrels for pneumatic and electric die grinders. It is rated for a maximum speed of 27,100 RPM, ensuring it can keep up with high-speed industrial tools for rapid material removal.
