High-Precision Needle File Set 9-Piece Kit for Gundam Models,Alloy Figures & Detail Sanding

Craft Every Detail with Surgical Precision

Whether you’re finishing a Gundam model kit, refining cast alloy figures, or cleaning up resin prints, rough edges and mold lines are the enemy of a flawless build. Our High-Precision Diamond Needle File Set gives you the control to remove material exactly where you want it — and nowhere else.

Each file is coated with industrial-grade diamond abrasive, delivering consistent cutting performance on metal, resin, plastic, and hard alloy surfaces without clogging or glazing over time.

What’s in the Box

This 9-piece set includes three of each profile — giving you backups for your most-used shapes and the flexibility to tackle any geometry:

• Square File ×3 — flat faces for slots, corners, and flat surfaces
• Half-Round File ×3 — curved face for concave contours and inner curves
• Triangle File ×3 — sharp edges for V-grooves, panel lines, and tight angles

Key Features

• 🔷 Diamond-coated abrasive — cuts harder materials that standard steel files skip over
• 🔷 Needle-file profile — slim, tapered body reaches recessed areas and fine detail zones
• 🔷 3 essential shapes × 3 each — redundancy for heavy users; share across a team or keep spares
• 🔷 Consistent grit — uniform coating for predictable, repeatable results
• 🔷 Durable construction — hardened steel core resists flex and breakage under pressure
• 🔷 Versatile compatibility — works on plastic, resin, soft metal, alloy, and composite materials

Who Is This For?

• Gundam and scale model builders who demand clean panel lines
• Figure collectors and customizers working with alloy or resin parts
• Miniature painters prepping surfaces before priming
• Jewelers and craftspeople needing fine metal finishing
• 3D print finishers removing layer lines and support marks

Frequently Asked Questions

Q: What materials can these files work on?

A: The diamond coating cuts effectively on plastic (ABS, polystyrene), resin, soft metals, alloy castings, and composite materials. They are not recommended for hardened steel or carbide.

Q: What is the grit level of these files?

A: These are medium-fine grit diamond files, ideal for shaping and smoothing. For final polishing, follow up with a finer sanding stick or polishing cloth.

Q: Why are there 3 of each shape instead of 1?

A: Heavy modelers go through files quickly. Having three of each means you always have a fresh file ready, can dedicate one per project, or share the set across a workshop without running short.

Q: Are these suitable for Gundam plastic runners (polystyrene)?

A: Yes. Diamond files cut polystyrene cleanly without melting or smearing the plastic, making them excellent for cleaning gate marks and mold lines on Gundam kits.

Q: How do I clean the files after use?

A: Brush away debris with a stiff-bristle brush or rinse under running water. Avoid soaking in solvents. Pat dry and store in the included case to protect the abrasive coating.

Q: What is the total piece count?

A: 9 files total — 3 square, 3 half-round, and 3 triangle needle files.
