3.5” x 4” x 3/4” quad key shaft Rubber Expanding Drums by Black Hawk Abrasives are designed to be used with BHA sanding bands. These 3.5 inch drums easily allow you to switch to a variety of grits and materials as the needs of a job change. The 3-1/2 inch diameter bladder wheel is manufactured with premium, flexible rubber and angled slits. This design allows the drum to expand and hold the belt tight while in use but, when stopped the sanding band can be slipped off and replaced with another. The expanding drums offer quick change versatility, easy portability, and a 4 inch wide sanding area which provides a great sanding surface area (when used in conjunction with sanding belt).
With it’s easy slip-on, slip-off usability and BHA’s wide range of compatible sanding bands, the rubber expanding drum combined with the sanding belts are perfect for a wide array of applications, including but, not limited to: paint and rust removal, wood sanding (including tables, decks, cabinetry ect.), metal preparation prior to buffing. These expanding drums are affixed with a hub that fits 3/4 inch keyed shaft and made to be used on surface finishing machines and linear grinding machines (A.K.A. Burnishers, burnishing machines, contouring grinders, etc.)

I've used these expander drums with good luck but the last one I got came apart. I contacted them and within days received a new one! Great customer service!
I was surprised how aggressive the 80 grit was. Thought I would need that, but 120 works fine for my metal art. Absolutely like this product. Much cheaper alternative to the mesh drum.
Used to sand acoustic guitar sides. They have the sleeves too. Works great.
This drum sander will quickly remove mill finish so a brush finish or polish can be obtained quickly. Nice product!
The drum worked perfectly with my Metabo burnisher!!!
quick shipping and good quality product .
Everything was fine but you need to stock 40 grit belts for the drum. 60 grit isn’t enough in some applications.
