Introducing the new C-Max Onglette for jewelry work, stone setting, and general engraving. The carbide material for C-Max gravers provides a superior edge to traditional tool metals. Try one today and see the difference for yourself. Years of development have now produced a tungsten carbide graver with the right blend of hardness and toughness for hand engraving and stone setting applications. C-Max achieves a metallurgical balance like no other carbide. For years, engravers and jewelers have used other carbide gravers that break easily or don’t hold a fine edge. Now, this frustration is gone forever, thanks to C-Max carbide. Try these tools and you’ll do better work in noticeably less time. C-Max Onglette gravers use QC Tool Holder for 1/8" Round .
