Circuit Board Drill Bits, Drill Bit Size (mm): 1.55 , Drill Point Angle: 130 , Shank Diameter (Inch): 1/8 , Flute Length (mm): 10.00 MPN:1017155

Circuit board drill bits are specialized cutting tools designed for precision drilling of holes in printed circuit boards or other soft materials like plastic or paper during manufacturing processes. Their unique design features a thin, sharp blade that creates clean, accurate holes without cracking or delaminating the substrate due to heat buildup. The 1/8'' shank diameter ensures easy insertion into handheld or benchtop drill presses while the 130-degree point angle reduces friction and pressure during start up, minimizing slippage or breaking of the delicate PCB material. With a flute length of 10mm, these bits provide efficient chip evacuation and prevent clogging even when drilling multiple holes close together. Their 1.55mm diameter ensures compatibility with most circuit board manufacturing standards, making them an ideal solution for electronics or semiconductor industries requiring precise, clean holes in PCBs or similar materials.
