OVERVIEW

Industrial Surface Conditioning with Walter Twist Blendex

The Walter 04F303 3" Twist Blendex Disc in Medium grade is a premium abrasive solution designed for MRO and industrial fabrication environments requiring efficiency and precision. Engineered with Walter's proprietary non-woven Blendex technology, this disc provides a consistent surface finish throughout its lifespan, making it an essential tool for surface preparation, cleaning, and blending operations. The open-web construction allows for cool cutting action, significantly reducing the risk of warping or discoloring thin gauge metals during processing.

Quick-Change Efficiency

Time is a critical factor in industrial workflows. The Twist quick-change system integrated into this disc allows operators to swap out abrasives in seconds without the need for additional tools. This feature is particularly beneficial in multi-step finishing processes where users must transition from stripping to blending and finally to finishing. The secure locking mechanism ensures the disc remains centered and stable even at high rotational speeds, minimizing vibration and operator fatigue.

Material Compatibility and Safety

Designed for versatility, the Walter Twist Blendex disc is effective on a wide range of materials, including stainless steel, carbon steel, aluminum, and non-ferrous alloys. Crucially for industries such as food processing, pharmaceutical, and nuclear manufacturing, this product is certified free of Iron, Sulfur, and Chlorine (Fe-S-Cl free). This guarantees that the abrasive will not introduce contaminants that could lead to corrosion or pitting on stainless steel surfaces, ensuring the integrity of the workpiece is maintained.

Technical Performance

The Medium grade grit offers a balanced performance between material removal and finish quality. It is aggressive enough to remove light oxidation, rust, and surface imperfections while leaving a smooth, uniform scratch pattern suitable for painting or further polishing. The 3-inch diameter is ideal for accessing tight corners, contours, and smaller surface areas that larger discs cannot reach effectively. Whether used for gasket removal, deburring edges, or blending weld seams, the 04F303 delivers reliable, high-quality results.

FAQ

The Twist system is compatible with Walter Twist backing pads and other standard Roloc-style or quick-change backing pads that support the twist-to-lock mechanism.

Yes, the Walter Twist Blendex disc is free of Iron, Sulfur, and Chlorine (Fe-S-Cl free), making it safe for stainless steel without causing contamination or corrosion.

The Medium grade indicates the coarseness of the abrasive. It is designed for general blending, cleaning, and surface conditioning, offering a balance between material removal and finish smoothness.

Yes, a compatible 3-inch backing pad with a Twist/Roloc-style attachment is required to mount this disc to your die grinder or power tool.

Absolutely. The open-web design helps prevent the disc from clogging (loading) with soft metals like aluminum, allowing for effective cleaning and blending.

While specific RPM can vary by batch, these 3-inch discs are typically rated for high-speed die grinders, often up to 20,000 RPM. Always check the label on the product for the exact safety limit.

No, this is a surface conditioning disc meant for blending and finishing. For removing heavy weld beads, you should start with a flap disc or grinding wheel before switching to this for the final finish.

A flap disc is primarily for stock removal and grinding, whereas the Blendex disc is a non-woven product designed for surface conditioning, satin finishing, and blending without removing significant amounts of base material.
