The PCB Drill Bit Set (0.35mm – 3.1mm) is designed for precision drilling and engraving on a wide range of materials including PCB boards, acrylic, plastics, fiberglass, aluminum, soft metals, and even jewelry. Crafted from ultra-fine grain tungsten carbide, these micro drill bits ensure exceptional durability, high hardness, and resistance to wear, making them a reliable choice for both professionals and hobbyists.
Featuring a spiral flute design, these bits provide sharp cutting edges that deliver smooth drilling while reducing cutting force and preventing breakage. The spiral chip space allows for fast, clean chip removal, ensuring accurate results with minimal effort. Their ability to withstand heat and bending makes them ideal for high-speed operations on CNC machines, engraving tools, and handheld rotary tools.
Each drill bit offers high precision milling and cutting performance, producing clean holes without glitches or burrs. Whether you are working on electronic components, circuit boards, jewelry making, or small-scale machining, these drill bits provide outstanding accuracy and reliability.
Compact, efficient, and versatile, the tungsten carbide PCB drill bits are an essential addition to any CNC toolkit, offering long service life and consistent performance across a variety of applications.
