OVERVIEW

Heavy-Duty Surface Conditioning for Industrial Fabrication

The Walter 07R450 Blendex Surface Conditioning Disc is engineered for industrial environments where efficiency and finish quality are paramount. This 4-1/2 inch disc features an Extra Coarse grit, making it the ideal choice for aggressive surface preparation tasks. Whether you are removing heavy scale, stripping tough paint, or cleaning up oxidation from stored metal stock, the Blendex disc delivers rapid results without compromising the integrity of the workpiece.

Constructed from a high-quality non-woven nylon matrix impregnated with abrasive grain, this disc is designed to resist loading. This is particularly beneficial when working with non-ferrous metals like aluminum, which tend to clog standard abrasives quickly. The open web structure allows for cool operation, reducing the risk of heat discoloration or warping on thin-gauge materials. For fabrication shops handling stainless steel, the Blendex system provides a consistent, uniform scratch pattern that is essential for preparing surfaces for subsequent finishing steps or coating applications.

This disc is compatible with standard 4-1/2 inch angle grinders, allowing operators to utilize their existing power tools for sophisticated finishing jobs. The flexibility of the non-woven material ensures that the disc conforms to curved surfaces, tube profiles, and irregular shapes, ensuring that every inch of the workpiece receives uniform treatment. From structural steel maintenance to architectural metal finishing, the Walter Blendex Extra Coarse disc is a versatile tool for the professional tradesperson.

FAQ

This specific disc (07R450) is Extra Coarse, designed for aggressive cleaning and material removal.

Yes, the non-woven construction resists loading, making it excellent for soft metals like aluminum as well as steel and stainless steel.

It is designed for use with a standard 4-1/2 inch angle grinder. Ensure you have the appropriate backing pad if required by your specific mounting system.

Yes, the Extra Coarse grit is aggressive enough to remove light to medium weld spatter and clean the surrounding area effectively.

No, the Blendex disc is designed to be more forgiving than a hard grinding wheel, removing surface contaminants while minimizing stock removal from the base metal.

A flap disc is primarily for stock removal and shaping, while the Blendex disc is for surface conditioning, cleaning, and finishing. Blendex leaves a smoother, more consistent finish.

It is best used for heavy-duty surface cleaning, such as removing thick rust, scale, or multiple layers of paint, before moving to finer grits for polishing.

Most surface conditioning discs require a backing pad for support. Check your grinder's setup; if this is a hook-and-loop or specific mounting style, a matching pad is needed.
