Tungsten Carbide Micro Drill Bits Set for PCB Print Circuit Board Engraving (30 Pcs, 0.3-1.2 mm)

Product Description

How should these drills be stored?

It is recommended to be careful when using PCB drills less than 0.5mm, as they are small and thin and easily damaged. The bit has high hardness and low toughness, so it is very fragile and may break if it falls to the ground.

What do you need to pay attention to when using it?

When using these drills, it is important to apply force evenly and vertically. Additionally, do not touch the blade with your hands or apply external force to avoid damage. These tungsten steel drills are mainly suitable for high-precision professional drilling equipment, such as PCB drill.

What materials are these drill bits suitable for?

This 0.01-0.05 inch drill bit set is suitable for precision drilling of amber beeswax, circuit boards, CNC engraved jewelry, hardware, plastics, and more. The package includes 30 pieces of drill bits divided into 3 groups, with 10 pieces in each group. They are made of quality tungsten steel, which is not easy to wear or bend. The anti-vibration design of the blade makes it stable and reliable during the engraving process, and ensures high machining accuracy with no burrs or debris.
