OVERVIEW

Master Tight Spaces with Walter Mini Flap Discs

When you are working on intricate car parts, railing corners, or detailed metal art, a standard 4.5-inch grinder just won't fit. That is where the Walter 2-1/2" Flap Disc comes in. This 80-grit mini disc is your go-to tool for smoothing out small welds and cleaning up surfaces in hard-to-reach areas. It brings the legendary performance of Walter abrasives down to a compact size, giving you the control and finish you need without the bulk.

Forget about constantly switching between a grinding wheel and a sanding disc. This flap disc is designed to do it all in one step. The 80-grit abrasive is aggressive enough to knock down small imperfections but refined enough to leave a smooth, professional finish. Whether you are working with stainless steel, aluminum, or regular mild steel, this disc handles it all without clogging or glazing over. It is the perfect companion for your die grinder.

Time is money in the shop, and the "TR" button mounting system respects that. It snaps on and off your backing pad with a simple twist—no tools required. This means you can swap grits or replace worn discs in seconds and get right back to welding. Sold in a convenient pack of 5, these discs ensure you have enough supply to get the job done right. Upgrade your finishing game with a disc that works as hard as you do.
