Walter Inox+ 3/4" x 18" File Belt, 120 Grit

Get Into Tight Spots with a Belt That Won't Quit

Every welder knows the frustration of trying to clean up a weld in a tight corner only to have your sanding belt snap or burn out halfway through the job. The Walter Inox+ 14B112 File Belt is designed to eliminate that headache. Sized at 3/4" x 18", this belt fits popular portable file sanders and is built to handle the abuse of daily fabrication work. Whether you are cleaning up inside corners on a railing, deburring a cut pipe, or blending a TIG weld on a stainless manifold, this belt gives you the control and durability you need to produce a professional finish without constantly stopping to change abrasives.

The secret to the Inox+ performance is in the backing and the coating. Walter uses a tough Y-polyester cloth that doesn't stretch out or tear easily, meaning you can really lean into the tool when you need to remove material. But power isn't everything—finesse matters too, especially on stainless steel. If you get the metal too hot, you end up with that dreaded blue discoloration (heat tint) that is a pain to remove. These belts are loaded with special additives that keep the cutting action cool. This means you can grind and blend longer without overheating the part, saving you from having to rework the piece or use chemical cleaners to fix heat marks.

With a 120 grit abrasive, this belt is your go-to for blending and refining. It is aggressive enough to take down light imperfections but fine enough to leave a smooth, consistent scratch pattern that looks great on finished goods. The smooth butt-joint construction means you won't feel that annoying "thump-thump-thump" every time the seam goes around the wheel, giving you better control and a cleaner finish. If you work with aluminum, you will also appreciate that these belts resist loading, keeping the grain open and cutting sharp. Upgrade your file sander with Walter Inox+ and experience the difference a premium belt makes on your finish quality and your patience.
