OVERVIEW

High-Performance Mini Flap Discs for Precision Finishing

The Walter 2-1/2" Flap Disc (40 Grit) represents a significant leap in efficiency for metalworkers dealing with intricate components and hard-to-reach areas. Designed to bridge the gap between standard grinding wheels and surface finishing pads, this mini flap disc offers aggressive material removal capabilities while maintaining a consistent finish. The 40 grit composition is specifically engineered for heavy stock removal, making it the ideal choice for leveling welds, removing heavy rust, or shaping metal surfaces before finer finishing steps are applied.

One of the standout features of this abrasive is its integrated plastic "TR" button. This mounting system, compatible with standard Type R backing pads, allows operators to switch discs in seconds without the need for wrenches or keys. This "turn-on, turn-off" functionality is crucial in high-production environments where downtime must be minimized. Whether you are working in an automotive repair shop, a custom fabrication facility, or an industrial maintenance setting, the ability to rapidly change from a stripping disc to a finishing disc streamlines the entire workflow.

Durability is at the core of Walter's abrasive technology. Unlike traditional sanding discs that may glaze over or tear quickly, these flap discs are constructed with layered abrasive cloth that exposes fresh grain as it wears. This design ensures that the cutting rate remains high throughout the life of the disc. Suitable for use on a wide range of materials—including mild steel, stainless steel, and aluminum—this product eliminates the need to carry multiple specific abrasives for different substrates. It provides a cost-effective, one-step solution for grinding and blending in confined spaces where larger 4-1/2" or 5" grinders simply cannot fit.

Key Industrial Benefits

  • Versatile Material Application: Safe and effective on ferrous and non-ferrous metals, preventing cross-contamination issues when used correctly.
  • Enhanced Accessibility: The 2-1/2 inch diameter is perfect for grinding inside pipes, channels, and tight corners.
  • Cost Efficiency: Long service life and high removal rates reduce the total cost per finished part.

FAQ

These discs feature a plastic "TR" button, which is a Type R quick-change mounting system compatible with Roloc-style backing pads.

Yes, these Walter flap discs are designed for use on aluminum, as well as steel and stainless steel, without clogging easily.

You will need a die grinder (pneumatic or electric) equipped with a 2-1/2" or appropriate size Type R backing pad.

No, 40 grit is a coarse abrasive intended for heavy stock removal and leveling welds. For a smooth final finish, you would typically follow up with a finer grit (e.g., 80 or 120).

This product is sold as a package of 5 flap discs.

Flap discs grind and blend in a single step and generally run cooler and smoother than solid grinding wheels, providing a better finish with less gouging.

Yes, they are excellent for stainless steel as they are designed to cut cool, reducing the risk of heat discoloration.
