Ruby Midget Files in the barrette profile offer jewelers, engravers, and mold-and-die professionals a precision finishing tool built from pure sintered synthetic ruby crystals. The barrette shape delivers controlled access to tight areas, flat surfaces, and detailed features where conventional abrasive tools fall short. These files hold their shape exceptionally well during use and can be reshaped or adjusted with diamond wheels and burs when needed. Features Made from pure, sintered crystals of synthetic ruby — no bonding material used Extremely hard and highly resistant to changes in shape, supporting precise, repeatable results Outstanding wear resistance makes these files more economical than comparable tools Barrette profile provides flat working surfaces ideal for fine detail work and edge access Can be reshaped and adjusted using diamond wheels and burs Compatible with ultrasonic handpiece use for fast deburring and blending in mold-and-die applications Applications Jewelers and Engravers: Polishing and shaping of carbide and high speed steel gravers Sharpening of carbide and high speed steel engravers and other tools Mold and Die Applications: Use in an ultrasonic handpiece for fast deburring and blending 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 the ruby stone to a fine point Polishing ribs and other hard-to-reach areas Specifications Dimensions 4" x 0.2" x 0.06" Profile Barrette Material Pure sintered synthetic ruby crystals — no bonding material Country of Origin Germany Suitable Materials Hardened tool steel, carbide, surgical stainless steel, high speed steel Notes Degussit Ruby Stones and Files are manufactured in Germany from pure sintered synthetic ruby with no bonding material, resulting in a tool of exceptional hardness and dimensional stability. This construction is particularly critical for quality precision grinding and finishing work where consistent geometry must be maintained throughout the life of the tool.
