Frequently Asked Questions
Q: What materials can these PCB micro drill bits cut through?
A: These tungsten carbide PCB drill bits are engineered for drilling through fiberglass PCB substrates (FR4), copper-clad laminates, circuit boards, thin plastics, and similar materials commonly used in electronics manufacturing and prototyping. Their hardness makes them well-suited for demanding micro-drilling tasks.
Q: Are these PCB drill bits compatible with CNC machines and rotary hand tools?
A: Yes. The straight shank design is compatible with most mini CNC routers, PCB drill presses, and standard rotary hand tools. Always match the collet or chuck size to the specific bit diameter you select to ensure a secure, accurate fit.
Q: Why is tungsten carbide better than high-speed steel (HSS) for PCB drilling?
A: Tungsten carbide is significantly harder and more heat-resistant than HSS, meaning it maintains a sharper cutting edge for longer — especially important when drilling through abrasive PCB materials like fiberglass. This translates to cleaner holes, less bit deflection, and more consistent results over the life of the bit.
Q: How many size options are available in this set?
A: This listing offers 4 specification/size options, allowing you to select the drill bit diameter that best suits your PCB or CNC drilling application. Choose the option that matches your required hole size before adding to cart.
