Please select the desired set from the variant options above. Each set contains 10 drill bits of different sizes.

2. Question:

What material are these drill bits made of?

Answer:

These drill bits are manufactured from high-speed steel (HSS), which offers excellent hardness, wear resistance, and heat resistance. They maintain their sharpness even after repeated use on various materials.

3. Question:

What materials can these drill bits be used on?

Answer:

These micro drill bits are suitable for drilling into plastic model kits (PS, ABS), resin, wood, soft metals (copper, aluminum, brass), PCBs, and jewelry materials. They are not recommended for hard steel or concrete.

4. Question:

What type of chuck/shank do these drill bits have?

Answer:

All bits feature a standard round shank design, compatible with most pin vises, rotary tools, micro drill chucks, and hobby drills. Please ensure your tool accepts the corresponding shank diameter (typically 2.35mm/3/32" for micro bits).

5. Question:

Are these drill bits suitable for model making?

Answer:

Absolutely. These precision micro drill bits are ideal for Gundam kits, scale models, miniature crafting, jewelry making, and PCB prototyping. The fine sizes allow for accurate hole drilling in small parts without cracking or damaging the material.

6. Question:

How durable are these HSS drill bits?

Answer:

HSS (High-Speed Steel) provides superior hardness and heat resistance compared to standard carbon steel bits. With proper use (appropriate speed and cooling), these bits maintain sharpness for extended periods and resist wear even on tougher materials.

7. Question:

How should I maintain and store these drill bits?

Answer:

After each use, clean the bits with a soft cloth to remove debris. Store them in a dry place to prevent rust. Avoid dropping the bits, as the fine tips may bend or break on impact. A protective case or drill bit holder is recommended for organized storage.

8. Question:

Can these drill bits be used with a power drill?

Answer:

Yes, they can be used with rotary tools (e.g., Dremel), micro power drills, and electric screwdrivers that accept small shank sizes. However, for delicate model parts, we recommend using a manual pin vise for better control and to prevent overheating or breaking.

9. Question:

Do these drill bits require cooling during use?

Answer:

For plastic, wood, and resin, cooling is generally not required. For metal drilling, we recommend using a small amount of cutting oil or water to reduce heat and extend bit life. Always use slow to medium speeds for better control and to prevent bit breakage.
