RobbJack/Crystallume will highlight a variety of cutting tools, including its PCD drills, which feature a solid diamond tip with geometry designed to shear better than typical flat-plane drills. Well-suited for composite materials, the drills can be resharpened, exhibit long tool life, and virtually eliminate delamination and fiber pullout, the company says. The W-point PCD drill is said to be especially well-suited for working with more problematic composites.
With increased metal removal rates over previous models, the NS Series of variable-helix cutting tools is designed to deliver faster speeds and feeds than traditional steel-cutting tools. Also on display will be threaded-shank tools, which are created from a single piece of solid carbide and are made with geometries specially designed for applications such as eliminating chatter, or enabling high-speed machining of titanium, aluminum or carbon fiber.
