Walter 3-1/2" x 5" Inflatable Sanding Drum 5/8-11 Arbor

Master Curved Surfaces and Satin Finishes

For welders and fabricators, achieving a seamless finish on curved surfaces like pipes, railings, and tanks can be a nightmare with rigid tools. The Walter Pneumatic Drum (07F037) solves this problem by using air to cushion your abrasive belt. Think of it as the suspension system for your finishing work. Because the drum is inflatable, it flexes and contours to the shape of your metal. This means you can grind and polish round tubing or domed ends without worrying about gouging the metal, creating flat spots, or leaving unsightly chatter marks. It gives you the "soft touch" needed for high-end architectural finishes.

This drum is sized at 3-1/2" diameter by 5" wide and comes ready to mount with a 5/8-11 threaded arbor. This standard thread allows you to attach it to compatible variable-speed grinders or surface finishing machines easily. The air cushion doesn't just help with shape; it helps with heat. We all know stainless steel loves to warp or turn blue if you look at it wrong. The air inside this drum helps dissipate heat, keeping the workpiece cooler and stopping your abrasive belts from burning out too fast. It turns a harsh grinding action into a smooth, controlled polishing motion.

Stop fighting your tools on irregular shapes. With the Walter Pneumatic Drum, you can blend welds and restore grain lines on elbows and corners as easily as you do on flat sheets. It eliminates the "bouncing" effect of hard rubber wheels, giving you a steady, even pressure that results in a professional, uniform appearance every time. If you are serious about stainless steel finishing, this inflatable drum is the secret weapon you need in your tool crib.
