3"x9" Rubber Sleeve Tube Pneumatic Drum Sander + 5Pcs 120 Grit Drum Sanding Sleeves Aluminum Oxide Sanding Belts Accessories for Woodworking,Furniture and Other Non-Metal Polishing

It is not 3" diameter. It's 70 mm = 2.756".(it is shown in one picture) The center hole is not 1". It's 25 mm which is less than 1". I had to grind it out to fit my 1" arbor. Good luck finding sleeves of different grit that fit. I've had to make my own and/or have them custom made.

I had to adapt it to work on a wood lathe.

Put it on the shelf for a project that I had not started yet. Just tried it, doesn’t hold air. Tried changing out the air core to see if that was the issue. Still not holding air

Using this product to sand older bamboo. - would have been nice to have a connection on where to buy replacements sandpaper on the website

Who designs something like this and doesnt make a mandrel for it. If you are going to use it in a lathe you can make one from almost anything. If you are like me and are going to attach it to a benchtop grinder, say your prayers.

haven't had a chance to use

Sleeves folded flat and stuck together, preventing them from use without tearing inside.Air intake too close to nut.Poor design

air leak
