Swiss-made, high-precision durable files by Glardon Vallorbe are manufactured from chrome alloy steel and heat treated by a special process to guarantee sharper teeth for outstanding cutting performance on all hard and soft metals, including platinum. These half-round ring files are tapered in width and thickness, then come to a point. They are more slim and slightly narrower than our regular half-round files; therefore these can used to file the insides of rings. Cut on both sides. Cut 0; coarse.
