Walter 2.5 Inch 120 Grit Mini Flap Disc with TR Mount

Master Tight Spaces with Walter's 2-1/2" Mini Flap Disc

For welders and fabricators, the finishing stage is often where the difference between a good job and a great job is made. The Walter 04A262 2-1/2" Flap Disc (120 Grit) is built to help you achieve that perfect finish, even in the tightest spots. We all know the frustration of trying to jam a standard angle grinder into a small corner or a narrow pipe section—it usually ends with gouges or an uneven finish. This mini flap disc solves that problem by bringing the power and durability of Walter's renowned flap discs into a compact, maneuverable format that fits right where you need it.

This disc isn't just about size; it's about speed and convenience. The 120 grit abrasive is perfect for that final pass, smoothing out grinder marks and blending welds seamlessly into the base metal. It is aggressive enough to remove light imperfections but controlled enough to leave a polished-looking surface on stainless steel, aluminum, or mild steel. Because it is a flap disc, it runs cooler and lasts longer than traditional sanding discs, meaning you spend more time working and less time changing out consumables. The layered flap design exposes fresh abrasive as you work, ensuring the cut rate stays consistent from the first spark to the last.

One of the standout features for the busy shop is the TR (Type R) mounting system. The plastic button on the back of the disc allows for a simple twist-on, twist-off attachment to your die grinder or mini angle sander. This quick-change capability is a game-changer when you are moving between heavy grinding and fine finishing. You don't have to hunt for a wrench; just twist, click, and go. Whether you are cleaning up TIG welds on a stainless manifold, deburring an aluminum bracket, or just doing general detail work, the Walter 04A262 gives you the control and finish quality you need to take pride in your work.
