{"product_id":"ruby-midget-files-half-round-degussit-4in","title":"Ruby Midget Files Half Round","description":"\u003cp\u003eRuby Midget Files in a half round profile are precision finishing tools 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, controlled work on the hardest metals. The files hold their form well during use and can be reshaped or adjusted with diamond wheels and burs when needed.\u003c\/p\u003e\n\n\u003cp\u003eRuby stones are the preferred choice for deburring, blending, dressing, and fine polishing of molds and dies made from hardened tool steel, carbide, and surgical stainless steel.
