07M444 - Walter Blendex Linear Finishing Drum 4-1/2" x 4" Fine Grit

Technical Overview of the Walter 07M444 Blendex Drum

The Walter Surface Technologies 07M444 Blendex Drum is a high-performance abrasive consumable designed for industrial surface conditioning and linear finishing applications. Engineered with Walter's proprietary Blendex non-woven technology, this drum is specifically formulated to deliver consistent, shadow-free finishes across a wide range of metallic substrates. The drum measures 4-1/2 inches in diameter with a 4-inch width and features a standard 5/8-inch arbor, making it compatible with the Walter Line-Mate III and other professional linear finishing tools commonly used in MRO and fabrication environments.

This specific unit features a "Fine" grit rating, positioning it as an essential tool for the final stages of surface preparation. It is particularly effective for polishing, burnishing, and blending operations where maintaining the geometric integrity of the workpiece is critical. The open-web structure of the non-woven material promotes airflow, significantly reducing heat generation at the contact point. This thermal management is crucial when working with heat-sensitive materials such as stainless steel, preventing discoloration or warping during the finishing process. Additionally, the structure resists loading, ensuring that the abrasive grain remains active and effective throughout the drum's extended service life.

Fabricators and industrial maintenance professionals rely on the 07M444 for its versatility. It is rated for use on steel, stainless steel, aluminum, brass, copper, and other alloys. Whether the task involves deburring machined parts, cleaning oxidation from aluminum, or creating a food-grade sanitary finish on stainless steel tanks, this drum provides a uniform scratch pattern that is easily reproducible. Manufactured in Germany to strict quality standards, the Walter Blendex Drum represents a reliable solution for shops demanding high-throughput finishing with minimal downtime for abrasive changes.
