07U653 - Walter Blendex U 6-Inch Unitized Deburring Wheel 6AM

Professional Grade Finishing with Blendex U

The Walter Surface Technologies 07U653 Blendex U Unitized Wheel is a premium abrasive tool designed for metalworkers who demand consistency, durability, and a superior surface finish. Measuring 6 inches in diameter with a 1/2-inch width and a 1-inch arbor, this wheel is engineered to fit a variety of stationary bench grinders and portable straight grinders. The "U" in Blendex U stands for "Unitized," a manufacturing process where layers of non-woven abrasive material are compressed and bonded together. This construction results in a tough, dense wheel that maintains its shape over time while offering enough flexibility to conform to the workpiece without gouging or altering the base geometry.

Versatile 6AM Specification

This specific model features a "6AM" rating, which decodes to a Density of 6, Aluminum Oxide grain, and Medium grit. The medium density (6) strikes an excellent balance between firmness for edge retention and compliance for surface blending. The Aluminum Oxide grain is a versatile abrasive suitable for a wide range of ferrous and non-ferrous metals. Whether you are deburring a sharp edge on a machined part, blending a weld seam, or applying a final satin finish, the 6AM grade provides a uniform scratch pattern that enhances the aesthetic and functional quality of the metal.

Applications and Material Compatibility

One of the standout features of the Blendex U wheel is its versatility across different materials. It is safe and effective for use on stainless steel, carbon steel, aluminum, brass, copper, and even titanium. The open structure of the non-woven material resists loading, meaning it won't clog up with debris even when working on softer, gummy metals like aluminum. This ensures the wheel continues to cut effectively throughout its lifespan. Common applications include removing minor scratches, cleaning oxidation, deburring laser-cut edges, and blending tool marks.

Durability and Performance

Unlike traditional grinding wheels that are designed for heavy stock removal, the Blendex U is a finishing specialist. It runs cool to prevent heat discoloration on sensitive alloys like stainless steel. The wheel can be utilized on both its face and its edge, allowing operators to reach into corners or work on flat surfaces with equal ease. With a maximum speed rating of 5,000 RPM, it is built to withstand the rigors of industrial environments while delivering a consistent finish part after part.
