Walter Topcut 3-Inch Zirconia Sanding Disc Grit 36 Type R

Grind Smarter with the Walter 3" Topcut Disc (Grit 36)

Every welder knows the frustration of trying to grind down a heavy weld in a tight corner where a standard angle grinder just won't fit. That's where the Walter 04D303 3-inch Topcut Disc shines. With a coarse 36 grit, this disc is built to bite. It rips through material aggressively, making short work of heavy stock removal and weld leveling. The secret lies in the Zirconia Alumina grain—it's tough, it stays sharp, and it doesn't glaze over halfway through the job. You get a consistent, aggressive cut from the first spark to the last, saving you time and effort on every project.

One of the biggest headaches in finishing work, especially on stainless steel, is heat buildup. Burn marks and blueing can ruin a perfect weld and force you to spend extra time polishing. Walter designed the Topcut series with a cool-cutting action that dissipates heat effectively, keeping your base metal cooler and preserving its integrity. Plus, the convenience of the TR (Type R) mounting system cannot be overstated. When you're in the zone, you don't want to be fumbling with wrenches. The plastic TR button allows you to snap the disc on and off with a simple twist, letting you swap grits or replace worn discs in seconds.

The color-coded backing is a simple but brilliant touch, letting you grab the right grit at a glance without squinting at worn-off labels. Whether you are working on aluminum, steel, or stainless, this disc gives you the control and power you need to get the job done right. It’s the perfect companion for your die grinder when precision and power are non-negotiable.
