04D210 - Walter Topcut 2-Inch Zirconia Sanding Disc 100 Grit Type R

The Welder's Choice for Tight Space Finishing

For professional welders and fabricators, the ability to access and finish tight corners and intricate geometries is often just as important as laying the bead itself. The Walter 2" Topcut Disc (04D210) is your go-to solution for those hard-to-reach areas where a standard 4.5-inch angle grinder simply won't fit. This 100-grit sanding disc is specifically tailored for the finishing stages of your workflow, allowing you to smooth out minor imperfections, blend weld toes, and prepare surfaces for painting or polishing without gouging the base metal.

The 100-grit abrasive is perfect for that intermediate to final stage of finishing. It removes material aggressively enough to be efficient but leaves a smooth enough scratch pattern that can be easily polished out or painted over. Because it uses a high-performance Zirconia alumina grain, this disc bites into the metal—be it mild steel, stainless, or aluminum—and keeps cutting long after cheaper discs would have glazed over. This means fewer disc changes for you and more time spent actually working. The cool-cutting properties are especially beneficial when working on stainless steel rails or aluminum tanks, where heat buildup can ruin the finish or weaken the material.

One of the best features for a busy shop is the "TR" button system. If you're swapping between grits or replacing a worn disc, you just twist it off and twist a new one on. No wrenches, no keys, just a quick snap and you're back to grinding. The discs are also color-coded, so you know exactly what grit you are grabbing from the bin. Whether you are cleaning up a custom exhaust, finishing a bracket, or doing detailed architectural work, this 2-inch Topcut disc gives you the control and longevity you need to produce a professional-grade finish every time.
