Custom Tool Spotlight – 8-Facet Brazed PCD Drill
Welcome to our Custom Tool Spotlight, where we highlight the unique GWS cutting tools that stand out in demanding applications. Today, we’re introducing a custom 2-flute 8-facet PCD drill, specifically designed for the aerospace industry.
What Is It For?
This tool is engineered for precision drilling in Carbon Fiber Reinforced Plastics (CFRP), whether in unidirectional or multi-directional weaves, as well as composite stacks like CFRP+Al and CFRP+Cu.
What Makes It Special?
PCD (polycrystalline diamond) offers unmatched wear resistance when machining highly abrasive non-ferrous materials like CFRP. Unlike diamond-coated tools, which can have edge rounding from CVD coating thickness, PCD maintains a sharper edge, leading to cleaner cuts and less delamination of composite layers.
This custom drill design features dual cutting angles to ensure clean, multi-directional fiber cutting. Additional thinning reduces tool walking, while the corner chamfer extends tool life and guarantees a smooth exit hole. Our proprietary production technology also allows GWS to produce PCD drills with diameters smaller than what is typically available in the industry.
Why Go Custom?
Material layup, thickness, and added material stacks can vary significantly, each requiring different geometries and design considerations. Additionally, specific customer requirements—such as entrance and exit hole finish, internal diameter tolerances, prevention of uncut fibers, and minimization of delamination—all influence the optimal drill design.
