07H365 - Walter Blendex Drum Belt 3.5 x 15.5 Inch Super Fine

Technical Overview: Walter Blendex Drum Belt (Super Fine)

The Walter 07H365 Blendex Drum Belt is a specialized abrasive consumable designed for linear finishing applications. Measuring 3.5 inches in width and 15.5 inches in length, this belt is engineered to fit standard drum sanders and linear finishing tools, such as the Walter Line-Mate III. The belt is constructed from Walter's proprietary Blendex non-woven material, which is impregnated with abrasive grain to provide a consistent cut and finish throughout the life of the product. This specific model features a Super Fine (SF) grade, identified by its grey color, making it the optimal choice for the final stages of surface conditioning where a smooth, uniform satin finish is required.

The open structure of the non-woven material helps prevent loading and heat accumulation, ensuring that the workpiece remains cool and the abrasive maintains its effectiveness. This is particularly critical when working with heat-sensitive alloys like stainless steel and aluminum. The belt is designed to clean, refine, and condition metal surfaces, effectively blending in directional lines and removing minor surface imperfections or fine scratches left by previous abrasive steps. It is an essential tool for fabricators requiring aesthetic precision on railings, tanks, and architectural metalwork.

Key Specifications and Compatibility

This drum belt is compatible with pneumatic and electric linear finishing tools that accommodate a 3.5" x 15.5" belt size. It is rated for use on a variety of metals, including steel, stainless steel, and aluminum. The Super Fine grit is typically used as the last step in a finishing sequence to achieve a high-quality decorative finish. The belt's flexibility allows it to conform to slightly curved surfaces, ensuring uniform contact and finish consistency across the entire workpiece.
