This flat (3x0.3mm) x 50mm long Ruby Midget
File is extremely useful when working on precision work with high detail. Ruby
Stones are always 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-steels. Jewelers use them for sharpening of
carbide and high-speed steel engravers and other tools. Measures 3mm x 0.3mm x 50mm long (approx. 0.12" x 0.012 x 2"). Ruby stone dimensions have
tolerance of ±0.1mm. Fine grit only.
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.
Mold & Die Applications:
Use in an Ultrasonic Handpiece for fast
deburring and blending. (Ruby Stones cut faster than our very popular Super
Ceramic Stones.)
Deburring ejector pin holes.
General deburring and edge breaking on mold
steel and carbide.
Blending a surface where a straight edge meets a
radius.
Polishing highly detailed areas on dies (after
dressing Ruby Stone to a fine point).
Polishing ribs and other hard to reach areas.
Medical Instruments:
Fine polishing of surgical stainless-steel
instruments.
Jewelers and Engravers:
Polishing and shaping of carbide &
high-speed steel gravers.
