FAQ

1. Question:

What are the available calibers and how do I choose the right one?

Answer:

This file is available in three calibers: 0.45mm (silver, MF-001SR), 0.55mm (red, MF-001RD), and 0.7mm (black, MF-001BK). Choose 0.45mm for ultra-fine detail work on small parts, 0.55mm for general-purpose hollow cutting, and 0.7mm for larger openings or thicker materials. Each caliber corresponds to a different color for easy identification.

2. Question:

What materials is this file made of? Is it durable?

Answer:

The file features a metal needle file head that is wear-resistant and durable, ensuring long-term use for model making and modification. The cap is made of durable plastic. The metal construction maintains its cutting precision even after repeated use on plastic and resin parts.

3. Question:

What is "precision hollow cutting" and how does this file achieve it?

Answer:

Precision hollow cutting refers to the ability to cut geometric hollow shapes (such as slots, vents, or panel openings) on model parts. The unique needle file texture enables multi-directional and irregular shape cutting, allowing you to quickly and accurately create hollow details that would be difficult to achieve with standard files or knives.

4. Question:

Can the cap be used as a handle?

Answer:

Yes. The cap serves a dual purpose: it can be used to store and protect the needle file when not in use, and it can also be attached to the other end to function as an extension handle for better grip and control during operation.

5. Question:

Is this file suitable for use in tight or narrow spaces?

Answer:

Absolutely. The miniature size and lightweight design make it easy to hold and operate, allowing for flexible maneuvering even in narrow spaces on model parts where larger tools cannot reach.

6. Question:

Do I need to drill a hole before using this file?

Answer:

Yes, for best results, we recommend using a suitable drill bit to create a pilot hole on the part you wish to modify. This provides a starting point for the needle file and helps guide the cutting process more accurately and safely.

7. Question:

How do I maintain the file and store it properly?

Answer:

After each use, simply rotate the cap to cover the needle file for protection and storage. This prevents accidental damage to the fine teeth and keeps the tool clean. Avoid dropping the file, as the fine needle tip may bend or break under heavy impact.
