07R702 - Walter 7-Inch Quick-Step Blendex Disc Coarse Grade

Professional Surface Conditioning with Walter Blendex

The Walter 07R702 7-inch Quick-Step Blendex Disc in Coarse grade is a premium abrasive solution designed for industrial surface conditioning applications. Engineered with a resilient non-woven nylon web impregnated with abrasive grain, this disc excels at bridging the gap between aggressive grinding and final polishing. The open structure of the Blendex material allows for cool cutting action, significantly reducing the risk of warping thin gauge metals or discoloring stainless steel surfaces due to heat buildup.

This specific SKU features Walter's proprietary Quick-Step backing system, a hook-and-loop interface that ensures secure fastening to the backing pad while enabling instantaneous disc changes. This is particularly advantageous in multi-step finishing processes where operators must switch between coarse, medium, and fine grades rapidly. The Coarse grade provided here is optimized for tough cleaning tasks, such as removing heavy oxidation, scale, and paint, as well as blending out light scratches left by previous abrasive steps.

Durability is a hallmark of the Blendex line. The uniform distribution of grain throughout the thickness of the disc ensures that the finish remains consistent from the first pass to the last. Unlike coated abrasives that can shed grain or load up quickly, the non-woven matrix sheds debris effectively, making it an excellent choice for working with soft, gummy materials like aluminum. Whether used in a fabrication shop, a maintenance department, or a production line, the 07R702 delivers reliable, high-quality results on steel, stainless steel, and non-ferrous alloys.

For optimal performance, this disc should be paired with a compatible Quick-Step backing pad (sold separately) and used within the recommended RPM range. Its flexibility allows it to conform to curved surfaces and irregular profiles, ensuring that every inch of the workpiece receives a uniform treatment without altering the base geometry.
