Custom Sizes - 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.

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.
