The Galahad CG® Round Disc is a quality made, long lasting tungsten carbide disc for the home and Do-It-Yourself market. The round profile is great for making convex or concave shapes (inward and outward curved surfaces) but it will also work well on straight surfaces. For weekend warriors who do general and light construction jobs around the house or employees on the job work site, nothing shapes wood better. It can be used on wood, plastic, polywood, rubber, and soft stone in any direction. Fast removal and safely shaping a variety of materials are features of this terrific and affordable disc. Landscaping, shaping rounded top fence, deck and posts, or quickly making awkward shapes fit together are some unusual applications for this great accessory.
