04G201 - Walter 2-Inch Twist Blendex Disc Extra Coarse

Heavy-Duty Surface Conditioning for Tight Spaces

The Walter 04G201 2" Twist Blendex Disc in Extra Coarse grit is a premium abrasive tool designed for industrial maintenance, repair, and fabrication environments where precision and efficiency are paramount. Engineered by Walter Surface Technologies, this disc utilizes a high-quality non-woven nylon web structure impregnated with aggressive abrasive grains. This unique construction allows the disc to remove heavy burrs, rust, scale, and coatings effectively while maintaining a cool cutting action that prevents heat discoloration on sensitive metals like stainless steel.

One of the standout features of this product is the "Twist" quick-change mounting system. Compatible with standard Type R (roll-on/roll-off) backing pads, the Twist system enables operators to swap out discs in seconds, significantly reducing downtime during multi-step finishing processes. The 2-inch diameter is specifically sized for accessing confined areas, corners, and contours that larger grinding wheels cannot reach. Whether you are cleaning up a weld in a tight angle or removing gasket material from a flange, the compact size and flexibility of the Blendex disc ensure consistent contact with the workpiece.

The "Extra Coarse" grade is the most aggressive in the Blendex lineup, making it the ideal choice for the initial stages of surface preparation. Despite its aggressive nature, the non-woven material provides a cushioning effect that helps prevent gouging or undercutting of the base metal, a common issue with traditional coated abrasives or bonded wheels. This results in a uniform surface profile that is ready for subsequent finishing steps or coating applications. The open-web design also resists loading, ensuring that the disc maintains its cutting efficiency throughout its long service life.

Key Industrial Applications

• Heavy Deburring: Rapidly removes sharp edges and burrs from machined parts and cut metal edges.
• Scale and Rust Removal: Aggressively cleans oxidized surfaces and mill scale without altering part geometry.
• Weld Cleaning: Cleans heat tint and slag from fillet welds in difficult-to-reach corners.
• Surface Preparation: Creates a consistent mechanical bond profile for paints, adhesives, and coatings.
