Frequently Asked Questions (FAQs)

1. What is a PCB drill bit?

PCB drill bits are used with power tools to remove material and create holes. PCB drill bits come in many sizes and shapes and can create different kinds of holes in many different materials.

2. What is used to drill holes in PCB?

High-speed steel (HSS) and tungsten carbide (WC) are commonly used drill bit materials for the drilling of composites. Carbide tools offer better tool life during the machining of glass fiber reinforced polymer (GFRP). The cemented carbide drills are generally used in PCB drilling.

3. Can you drill holes in PCB?

PCB drilling, or printed circuit board drilling, is the process of creating holes, slots, and other cavities into an electronic circuit board before soldering/mounting components onto it. It is typically done by using a PCB drill bit (an automated machine) that is slightly smaller than the components placed on it.

4. What size of drill bit is used in making holes in the PCB?

So, you want at least two 0.8mm drill bits in your rack since small bits tend to be brittle and break easily. 1.0mm and more significant bits are more resilient, but you should always have at least one spare just in case. You also want to make sure your holes are about 0.007 mm larger than your leads.
