PCB Drill Bit

Upgrade your precision drilling tasks with this Tungsten Carbide PCB Drill Bit Set (0.35mm – 3.1mm), designed for CNC machines, engraving tools, 3D printers, and hand-held rotary tools. Crafted from ultra-fine grain tungsten carbide, these micro drill bits offer exceptional hardness, wear resistance, and high strength, ensuring precise, smooth, and reliable performance.

The spiral flute design provides a sharp cutting edge for smooth drilling, reduces cutting force, prevents breakage, and allows for fast, clean chip removal. Each bit guarantees high precision milling, clean surfaces, and minimal scrap, making it ideal for delicate electronics, jewelry, and small-scale machining projects.

With a high-speed steel shank, these bits can operate at higher speeds while maintaining excellent toughness. Perfect for creating tiny holes on PCB boards or working with acrylic, plastics, fiberglass, wood, aluminum, and soft metals, these drill bits deliver superior accuracy and efficiency for both professional and hobbyist use.

Whether you’re working on PCB fabrication, SMT assembly, mold making, or electronic parts processing, these micro drill bits provide consistent quality, durability, and reliable results every time.
