07U612 - Walter Blendex U 6-Inch Unitized Wheel 6SF

Technical Overview of the Walter Blendex U Unitized Wheel

The Walter 07U612 Blendex U is a premium unitized wheel designed for precision surface conditioning in industrial MRO and fabrication environments. Engineered with a compressed non-woven nylon matrix impregnated with high-quality abrasive grains, this wheel offers a density rating of 6, providing a balanced stiffness that is ideal for general purpose deburring and finishing applications. The "SF" designation indicates a Super Fine grit, typically utilizing Silicon Carbide, which is renowned for producing bright, consistent finishes on stainless steel and other alloys.

Unlike bonded abrasive wheels that remove significant material, the Blendex U is designed to condition the surface. Its unitized structure allows it to conform slightly to the workpiece, effectively removing burrs and blending tool marks without gouging or altering the critical geometry of the part. This makes it an essential tool for machine shops requiring tight tolerances. The open-web structure promotes airflow, significantly reducing heat generation and preventing thermal discoloration (heat tint) on sensitive materials like stainless steel and titanium.

This 6-inch wheel features a 1-inch width and a 1-inch arbor, making it compatible with a wide range of stationary bench grinders and pedestal machines. It is rated for a maximum speed of 5,000 RPM. The non-loading properties of the Blendex U technology ensure that the wheel remains effective even when processing softer, gummy metals such as aluminum, copper, and brass. Operators can expect a long service life and a consistent Ra (Roughness Average) finish throughout the lifespan of the product.
