Ruby Midget Files are invaluable for high detail and ultra-precision work. They may be broken off and cemented onto a holder or used with a pin vise. All measure approximately 2 inches in length (50mm) and are available only in fine grit. Midget files are made in Germany from pure, sintered crystals of synthetic ruby. No bonding material is used, so these stones and files are extremely hard and resistant to changes in shape. This is particularly important for quality precision grinding and finishing.
In addition, since Degussit Ruby Stones and Files feature outstanding resistance to wear, they are more economical to use than other comparable tools.
Use dry or with Gesswein Stoning Oil to grind, touch up or debur steel and carbide parts. Also recommended for use on materials such as glass, quartz and porcelain.
Ruby Stones are the ideal choice for deburring, blending, dressing, and fine polishing of molds & dies made of hard metals such as hardened tool steel, carbide and surgical stainless steel. Jewelers use them for sharpening of carbide and high speed steel engravers and other tools.
Can be used in an Ultrasonic Handpiece for fast deburring and blending. These sizes are often used to debur ejector pin holes, as well as polishing ribs and other hard to reach areas.
