{"product_id":"ruby-midget-file-round-degussit-sintered","title":"Ruby Midget File Round","description":"\u003cp\u003eRuby Midget Files are precision abrasive tools made from pure, sintered crystals of synthetic ruby with no bonding material — resulting in exceptional hardness and outstanding resistance to changes in shape. These round-profile files are ideal for jewelers, engravers, and mold and die professionals who demand accuracy and longevity from their finishing tools. The ruby files hold their shape well, but can be reshaped and adjusted with diamond wheels and burs.\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.
