BD-5000 Air Grinder

The MK-1503 Wet Polishing Lapidary Kit is ideal for handheld grinding and polishing of gemstone and rock materials such as onyx, agate, petrified wood, jade, opal, etc. The polisher is used with the vacuum brazed convex wheel for aggressive shaping and grinding, contour carving and sculpting of the material. Resin diamond discs are used sequentially for polishing. The polisher easily attaches to a standard hose to enable the unit to dispense a steady flow of water to diamond pads and grinding wheels. The 4" flexible rubber Hook & Loop backer pad allows for quick pad changes.
