Uxcell 20 Pack Micro PCB Drill Bits 1.5mm Tungsten Steel with 1/8" Shank for Printed Circuit Board Stone CNC Engraving

Micro PCB drill bits were specifically designed for precision drilling. The Tungsten material features high hardness, high strength, heat resistance, wear resistance, deformation resistance, and long-lasting performance. With their precision-ground tips and enhanced rigidity, they ensure optimal hole quality, thereby enhancing the overall performance and reliability of the PCB. The meticulous symmetry of these edges is great for promoting cutting actions and avoiding any lateral displacement during the drilling process. Tungsten steel Carbide drill bit set is designed for PCB, CNC engraving and other high-precision hole required equipment, suitable for electronic boards, SMT, amber, hardware and other precision parts of the drilling process.
