Expanding Drums
These drums are a must for sanding and polishing belts. Soft, pliable rubber expands during rotation to grip the sanding or polishing belt. Changes are made quickly and easily by sliding the belts from the drum. At slow speed the flexible surface wraps around the curved surfaces for increased contact with the work piece. When using at high speed, the drum acts like a hard rubber grinding wheel. Use with diamond or silicon carbide abrasive belts and any of our polishing belts. 1 inch arbor and is supplied with bushing to fit 3/4", 5/8", and 1/2" arbors.
Silicon Carbide Belts and Discs

Eastwind Diamond Sanding Belts and Pads
Made in the USA Eastwind diamond sanding belts and pads are resin bonded giving a nice smooth finish, especially after working a few stones. Our professional people tell us they are the longest lasting belts they have ever used. In fact, under normal use, our belts will last 50 to 100 times longer than silicon carbide abrasives! Besides being made right here in the US, they are priced right. Of course, we back these belts with our 100% satisfaction guarantee.

Custom sizes available. Graves can supply our Eastwind brand of diamond belts and discs in almost any size you need. Belts can be joined or made as a continuous length for split drums. To determine the cost, simply calculate the area of your belt/disc in square inches. Multiply the area by $1.00 to determine your price. Example: You need a 42 inch long and 3 inch wide belt for your belt sander. 42 x 3 = 126 square inches. 126 square inches x $1.00 = $126.00. Email us your requirements. Shipping normally takes 4-5 days after you place your order for custom sizes, some sizes may take longer.
