OVERVIEW

Fast Finishing for Tight Spots

When you are stuck trying to clean up a weld inside a corner or smooth out a jagged edge in a tight bracket, a standard 4.5-inch grinder just won't fit. That is where the Walter Spinlock A/O Resin Fiber Disc, 2" G80 comes in to save the day. This little powerhouse is designed to get into those hard-to-reach places and get the job done fast. With its 80-grit Aluminum Oxide abrasive, it is aggressive enough to knock down small burrs and blend light welds, but fine enough to leave a smooth, clean surface ready for paint or further polishing.

The best part about this disc is the Spinlock system. We all know that time is money, and fumbling around with wrenches to change a worn-out disc is a waste of both. With Spinlock, you just twist the old disc off and twist the new one on—it takes seconds. The connection is solid, so you don't have to worry about the disc flying off or wobbling while you are grinding. It centers itself perfectly every time, giving you a smooth run that won't numb your hands after five minutes of work.

This disc is a true multi-tasker. Whether you are working on mild steel, stainless steel, or aluminum, the premium grain holds up and keeps cutting. It is perfect for prepping surfaces for welding, cleaning up after a repair, or just making your fabrication work look professional. The resin fiber backing is tough; it doesn't tear easily like cheap paper discs, meaning you get more life out of every single one. Toss a pack of these in your toolbox, and you will be ready for any detail work that comes your way.

FAQ

The Spinlock system is Walter's proprietary name for the popular Type R (plastic threaded button) quick-change attachment style. It is generally compatible with standard Type R backing pads.

Yes, the Aluminum Oxide grain is suitable for use on aluminum, as well as steel and stainless steel. However, for heavy aluminum work, a specialized lubricant or wax may help prevent loading.

While specific max RPMs are printed on the packaging (typically around 20,000-30,000 RPM for 2-inch discs), it is best used with high-speed die grinders or right-angle air tools designed for small abrasives.

80 grit is a medium-grade abrasive. It is better suited for blending, light stock removal, and finishing. For heavy slag or aggressive stock removal, a coarser grit like 36 or 50 would be faster.

Yes, a compatible 2-inch backing pad with the correct quick-change receiver is required to mount this disc to your power tool.

A resin fiber disc is a single layer of abrasive coated on a fiber backing, offering a flat, consistent cut. A flap disc has layered flaps that wear down to reveal new grain. Fiber discs are often better for flat blending, while flap discs last longer.

This product is widely used in aerospace, automotive repair, metal fabrication, and general MRO where precision finishing in small areas is required.

Likely not directly. Most Dremel tools use a 1/8" shank mandrel. This disc requires a backing pad typically mounted on a 1/4" collet die grinder or pneumatic tool.
