Accurate Holes for Miniature Models

The Tamiya 74128 is built for precision work, combining a 0.7mm tip with a 1.0mm shaft to produce small, clean holes in delicate parts. It is a handy addition for anyone trimming or modifying detailed model sections.

Where to Use It

This bit works well for making pilot holes in plastic body panels, drilling small mounting holes for servo fittings, and opening tiny ports in electronics housings. Its fine size helps preserve part integrity.

Fit and Handling

Compatible with standard pin vises, the Tamiya 74128 sits securely thanks to the 1.0mm shaft diameter. Controlled hand operation provides the best results when working on tight detail areas.

Is the Tamiya 74128 suitable for metal work?

It can drill thin metal used in model parts but go slowly and clamp the piece to prevent vibration or distortion.

How often should I replace the bit?

Replace it when you notice dulling or when hole quality drops; frequent use on harder materials will shorten its life.

Can I use a handheld electric pen drill?

Yes, if the pen drill accepts a 1.0mm shaft and you keep speed and pressure low to avoid overheating the bit.

What is the best way to clear swarf?

Withdraw the bit periodically, brush or blow away debris, and use a drop of cutting oil on metal to ease chip removal.
