3長充氣鼓 1/4柄 #11371

The inflatable drum expanded nicely to hold the abrasive firmly on my rotary tool, and the 1/4 shank made swapping bits quick. Works just as needed for smoothing small curved surfaces.

The 1/4 shank fits my rotary tool perfectly — no wobble at all. Even with repeated use on curved surfaces, the drum holds its shape and doesn't deflate. Really glad I found this specific size.

Got this for sanding inside tight curved areas and it works exactly as needed—the 3-inch length gives me way better reach than my usual attachments. The rubber inflates evenly and holds up to moderate pressure without tearing. Really happy it’s so easy to swap out on my rotary tool.
