Perma grit tools

Conventional files are made from hardened steel and have a serrated cutting surface. Once this edge is worn, the file will not cut effectively and will need replacing. Perma-Grit tools however, are made from a much harder material, and have thousands of individual cutting edges, enabling them to cut in any direction and last longer. The grit spacing is much wider than conventional sandpapers, which keeps the cutting surface cleaner and prevents them from loading.

The tools were demonstrated and sold to many different composite aircraft manufacturers and builders from around the world. The unique safe edge will protect the sanding face against damage. Spar Slotters - Perma-Grit has re-introduced these very useful spar slotting tools in 3 convenient sizes. These 6" long steel bars have the Tungsten Carbide course grit bonded to one side allowing neat, true slots to be cut into plywood, balsa or composite formers and ribs. Two sizes available, SP9C has been discontinued.

Radius Tools No need to glue sandpaper to dowels anymore! The handle is a smaller radius than the cutting face, making these tools perfect for wing fillets, tail fillets and all concave curves. Use them for openings on both plastics and fiberglass cowlings, etc. Perma-Grit will not cause paint to chip or flake off when modifying a finished item. Remember, Perma-Grit cuts foam, wood and glue joints all with ease.
