About Perma-Grit Tools
Since 1991, Perma-Grit®Tools have been manufacturing and developing a range of professional abrasive tools. Traditional tools are not efficient at sanding or shaping composite materials, having a tendency to either chip or melt them. Ian Richardson Managing Director of Perma-Grit, is a 5 times World Champion Scale aircraft builder. Ian needed some serious tools, for the diverse range of materials he was working with. If you can't buy the tools you need, then make them!
"Everything started with a model".
Perma-Grit tools are made by brazing Tungsten Carbide Grit to steel in a furnace. This produces a permanent bond of the grit to the surface. This abrasive will cut the softest materials, to some of the hardest, giving far better results, than conventional files.
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.
Back in the early 90’s, Perma-Grit tools attended the Experimental Aircraft Association ( EAA ) shows at Oshkosh, and Sun & Fun in Lakeland, USA. The tools were demonstrated and sold to many different composite aircraft manufacturers and builders from around the world. For many years, Perma-Grit tools have been used and recommended by EAA at their workshop building courses.
More recently, Perma-Grit has expanded into the race-car market, and Perma-Grit products are used by the leading MotorSport teams, and composite fabricators throughout Europe.
In December 2006, the company attended the "Performance Race Industry” show in Orlando, USA.
Both car and component fabricators were impressed by the cutting and sanding abilities of Permagrit tools.
