Walter Soft Pneumatic Drum 3.5 Inch M14 Thread

Master Curved Finishes with the Walter Soft Pneumatic Drum

Finishing curved surfaces, such as stainless steel tubing or handrails, presents a unique challenge for welders and fabricators. A rigid backing pad or hard drum can easily dig into the metal, creating unsightly flat spots that ruin the profile of the pipe. The Walter 07F036 Pneumatic Drum (Soft) is the solution to this problem. Designed with an M14 thread for compatible linear finishing tools, this drum features an inflatable rubber bladder that cushions your abrasive belt, allowing it to float over the surface of your workpiece.

Think of this drum as the suspension system for your finishing tool. By adjusting the air pressure, you can customize how the drum behaves. Keep it softer for delicate blending work where you need the belt to hug the contours of a round pipe, or firm it up slightly for flat surfaces. The "Soft" designation of this specific model (07F036) means it is optimized for maximum flexibility and conformity. It is the ideal choice when you are looking to achieve a seamless satin or mirror finish on architectural metalwork where appearance is everything.

Using the Walter Pneumatic Drum is simple. Slide your abrasive belt or non-woven conditioning belt over the deflated drum, then inflate it just enough to secure the belt. The centrifugal force during operation will help hold the belt in place, while the air cushion absorbs vibration and chatter. This results in a smoother, more consistent scratch pattern and reduces operator fatigue. Whether you are cleaning up TIG welds on a food-grade stainless tank or polishing brass railings for a hotel lobby, this M14 pneumatic drum gives you the control and finesse required for professional results.
