Glastar (B12) 12" Diamond Disc Grinder
When looking for an exceptional diamond grinder, you can’t go wrong with the Glastar Disc Grinder model B12, which offers the fastest and most economical way to grind glass or stone. Featuring a large 12" grinding surface and a powerful high-speed motor, this glass grinder pays for itself in a very short time. The B12 Disc Grinder is the only 12" lap that is direct drive. It does not rely on belts or pulleys. Instead, it employs a huge 3/4 HP motor that does not lose speed even during heavy continuous use.
This beveler is also available with a 1/3 HP variable speed motor, which makes it possible to keep the speed of the disc as slow as possible for polishing and yet stays above the minimum recommended grinding speed. Grinding at too slow of speed reduces diamond life and makes getting the work done take that much longer.
A magnetic holder holds the grinding and polishing pads in place, but takes only seconds to change out.
NOTE: This machine does not include any grinding discs or accessories, each must be purchased separately.
