04U321 - Walter Blendex U 3-Inch Unitized Quick-Change Disc 2SF

Professional Surface Finishing with Blendex U

The Walter Surface Technologies Blendex U Twist-2SF (SKU: 04U321) is a premium 3-inch unitized disc designed for MRO professionals who demand consistency and efficiency. Engineered with a compressed, non-woven structure, this disc excels at deburring, cleaning, and blending in a single step. The "U" in Blendex U stands for Unitized, a manufacturing process that compresses layers of abrasive material into a dense, durable slab, which is then cut into discs. This construction ensures that the disc maintains its shape while offering enough flexibility to conform to complex contours and tight corners.

The 2SF grade indicates a Density 2 (Soft) construction paired with Fine Silicon Carbide abrasives. This specific combination is perfect for delicate finishing tasks where maintaining the geometry of the workpiece is critical. It provides a smooth, uniform satin finish on stainless steel, titanium, and aluminum without gouging or undercutting. The silicon carbide grain is sharp yet friable, delivering a bright finish that is often required in food processing, pharmaceutical, and aerospace applications.

Efficiency is maximized through the Twist Quick-Change system. This integral mounting mechanism allows operators to swap discs on their die grinders in seconds without the need for wrenches or tools. This feature is invaluable in multi-stage finishing processes where an operator might switch from a coarser grit to the 2SF for the final polish. Whether you are removing heat tint, smoothing rough edges, or preparing surfaces for painting, the Blendex U Twist-2SF delivers reliable, industrial-grade performance.

Key Industrial Benefits

• Consistent Wear: The uniform distribution of grain ensures the finish remains constant down to the last layer.
• Cool Running: The open structure dissipates heat, preventing warping or discoloration on heat-sensitive alloys.
• Versatility: Effective on a wide range of materials including carbon steel, brass, copper, and exotic alloys.
