{"product_id":"ruby-midget-file-oval-degussit-4in","title":"Ruby Midget File Oval","description":"\u003cp\u003eThe Ruby Midget File in an oval profile is a precision finishing tool made from pure, sintered crystals of synthetic ruby — manufactured in Germany under the Degussit standard with no bonding material. This construction results in an exceptionally hard file that resists changes in shape, making it ideal for fine, repeatable work on the hardest materials. The file measures \u003cstrong\u003e4\" × 0.16\" × 0.06\"\u003c\/strong\u003e and can be reshaped or adjusted using diamond wheels and burs when needed.\u003c\/p\u003e\n\n\u003cp\u003eRuby stones are the ideal choice for deburring, blending, dressing, and fine polishing of molds and dies made of hard metals such as hardened tool steel, carbide, and surgical stainless steel.
