Walter 2-Inch Spinlock Zirconia Sanding Disc 80 Grit

Snap On, Grind Down, Move On

When you are deep in a fabrication job, the last thing you want to do is wrestle with your tools. The Walter Spinlock Z/A Resin Fiber Disc is built for welders who need to get into tight corners and get the job done fast. This 2-inch disc is a powerhouse for small surface work. Whether you are cleaning up a tack weld, deburring a freshly cut edge, or prepping a small bracket for paint, this disc gives you the control and bite you need. The 80-grit abrasive is your perfect middle-ground utility player—it removes material quickly but doesn't leave deep gouges that take forever to fix.

The secret sauce here is the Zirconia Alumina (Z/A) grain. Unlike cheaper aluminum oxide discs that dull out after a few passes, Zirconia grains actually micro-fracture as you grind. This means they keep creating new, sharp cutting edges right down to the backing. It eats through steel and stainless steel without generating excessive heat, which saves your workpiece from warping or turning that dreaded rainbow color. If you work with aluminum, it resists loading better than standard discs, keeping you grinding longer.

Let's talk about the mounting system. Time is money in the shop. The Spinlock system (compatible with Type R or Roloc-style pads) lets you swap out a worn disc for a fresh one with just a quick twist. No wrenches, no keys, no hassle. Just snap it on and get back to making sparks. This disc is designed to run smooth on your die grinder, giving you the stability to do detail work without the tool jumping around. Add a pack of these to your consumables locker and stop wasting time with inferior abrasives that can't handle the heat of a real welding shop.

Perfect for Tight Spaces

• Corner Welds: Easily reach into 90-degree angles where a flap disc won't fit.
• Auto Body: Great for spot weld removal and small rust patch cleanup.
• Pipe Work: Ideal for prepping beveled edges on small diameter pipe fittings.
