Joyjet' s PCD (Polycrystalline Diamond) micro drills are engineered for ultra-precision micro-hole drilling in challenging materials such as high-silicon aluminum alloys, copper alloys, ceramics, and composites. They offer exceptional tool life, extreme accuracy, and reliable process stability for demanding micro-machining applications.
Ultra-High Hardness: Diamond hardness up to HV8000–10000
Minimized Built-Up Edge: Reduces burr formation and prevents wall tearing, extending drill life
High-Rigidity Shank: Made with ultra-fine grain carbide substrates to reduce the risk of micro drill breakage
