PCB Drill Bit

PCB drill bits are specialized cutting tools designed for creating precise holes in printed circuit boards (PCBs) for mounting electronic components and forming electrical connections. Made from high-speed steel (HSS) or tungsten carbide, these drill bits offer exceptional hardness, wear resistance, and durability, making them ideal for drilling through tough materials like fiberglass-reinforced epoxy laminates (such as FR-4). They are typically available in extremely small diameters ranging from to accommodate the tiny vias and through-holes required in modern PCBs. The bits are engineered with high precision to ensure clean, burr-free holes.
