These new C-Max Carbide tools from GRS improve the efficiency of stone setting and engraving jobs by providing a carefully-sized tool point. Stone setters will save time removing the metal between and around stones in pavé and other setting jobs. Engravers can shape small tools without the hassle of starting with a tool blank that is too big for the job. The 2.35 mm C-Max carbide shanks are precisely ground to eight different diameters: 0.8 mm to 2.2 mm, in 0.2 mm steps. A finely-tapered point perfect for stippling or texturing is also available.
