11L453 - Walter ZIP GRIND 4-Inch Die Grinder Wheel Type 1

High-Performance Grinding for Die Grinders

The Walter ZIP GRIND™ (SKU: 11L453) is a premium reinforced grinding wheel designed specifically for use with straight shaft and die grinders. Measuring 4 inches in diameter with a substantial 1/2-inch thickness and a 3/8-inch arbor hole, this wheel is engineered to tackle heavy-duty grinding tasks in confined spaces where larger angle grinders cannot reach. It features a Type 1 (flat) profile, making it ideal for smoothing welds, beveling, and general shaping of metal components.

Constructed with Walter's proprietary abrasive grain blend, the ZIP GRIND wheel delivers an exceptional material removal rate while maintaining a cool cutting action. This thermal management is critical when working with heat-sensitive materials like stainless steel, as it significantly reduces the risk of heat discoloration, warping, or blueing of the workpiece. The wheel is manufactured to be free of iron, sulfur, and chlorine (Fe-S-Cl < 0.1%), ensuring it will not contaminate stainless steel or other exotic alloys, making it suitable for nuclear, food, and pharmaceutical industry applications.

Durability and safety are paramount in the design of the 11L453. The internal reinforcement allows the wheel to withstand the high rotational speeds of pneumatic and electric die grinders (rated up to 15,300 RPM). Additionally, the wheel is balanced to minimize vibration, which reduces operator fatigue during extended use and prevents chatter marks on the metal surface. Whether used for maintenance, repair, or fabrication, this wheel provides consistent performance and a long service life.
