FAQ

1. Question:

What is the drilling range of this manual hole punch?

Answer:

This manual reamer has an adjustable drilling range from 0 to 14mm. The graduated scale on the tool allows you to accurately determine the depth and diameter of the hole you are drilling.

2. Question:

What materials can this hole punch be used on?

Answer:

This tool is widely applicable for opening holes in model shells, plastic carbon boards, wooden boards, and other soft materials. It is ideal for plastic models (Gundam, cars, aircraft), balsa wood, plywood, acrylic sheets, and similar hobby materials. It is not suitable for metal or hard steel.

3. Question:

How does the graduated scale work?

Answer:

The reamer features a clear 0-14mm graduated scale marked on the body. As you turn the tool, you can read the scale to monitor the hole diameter in real time, allowing for precise, repeatable hole sizing without the need for separate measuring tools.

4. Question:

What is the handle designed for comfortable use?

Answer:

The handle is made of hollow aluminum alloy with a mesh texture for a non-slip, comfortable grip. It is lightweight and easy to carry. Additionally, the handle features a through-hole design that allows you to insert a pry bar for extra leverage when turning larger holes.

5. Question:

How do I operate this manual hole punch reamer tool?

Answer:

Simply rotate the top of the reamer to start drilling. The top is designed for easy hand-turning, requiring no power tools. For larger holes, insert a pry bar through the handle's through-hole to increase torque. Apply steady, even pressure while turning for clean, precise holes.

6. Question:

What material is the cutting tip made of?

Answer:

The cutting tip is made of bearing steel, which is hardened and wear-resistant. The handle body is made of black aluminum alloy – strong yet lightweight. This combination ensures durability while keeping the tool easy to handle.

7. Question:

Is this tool suitable for model making?

Answer:

Absolutely. It is an essential tool for model makers who need to create precise holes in plastic model parts (Gundam, cars, ships, aircraft), carbon plates, and wooden bases. The adjustable range from 0-14mm covers most hole sizes needed in hobby modeling.

8. Question:

How should I maintain and store this tool?

Answer:

After each use, clean the tool with a soft cloth to remove debris. Store in a dry place to prevent rust on the bearing steel tip. Avoid dropping the tool, as the tip may chip or crack under impact. Keep it in a protective case or pouch when not in use.
