Perma-Grit Tools are made of Tungsten Carbide Grit, one of the hardest elements available, second only to diamonds. They are specifically designed and developed for aircraft builders, woodworkers, and modelers. These tools will cut, sand and shape tough composite materials, saving homebuilders hours of building time. Ideal for fuselage shaping and wing building, these tools are highly recommended by several kitplane manufacturers. Available in coarse (180) & fine (320) grit.

Very well built. It fit all of my files except the big one. Very glad I invested in it.

I really like the Perma-Grit File. I will order another. I discovered it works great on my toe nails. It was a little ruff the first time I tried it on my toe nails, so I slightly kissed it with my belt sander. Now it is a wonderful toe nail file, and finger nail file also.

I have used these for a long time and they work fantastic and last for years. They are great for shaping woods, plastics, composites, soft metals, etc. Besides modeling, I use them on household projects too.

The Perma-grit tools are great. I work with wood a lot and they get the job done with out wasting a lot of sand paper. For wood Composites and modeling they are just outstanding .

This tool set is a must have for building a composite airplane or any other composite structure. Wish I would have found them at the beginning of my build. The tools never wear out or become clogged with material. I love them...
