Fine Drilling for Scale RC Parts

The Tamiya 74128 drill bit gives hobbyists a reliable 0.7mm cutting tip paired with a 1.0mm shaft for accurate holes in small components. It is made for careful work where a clean, repeatable result matters on fragile model parts.

Best Uses

This micro bit is excellent for installing tiny screws, preparing pilot holes in thin plastic panels, and making precise openings for small electronics. Its small diameter helps prevent splitting and keeps fittings snug.

Tool Compatibility

Designed to fit common pin vises, the Tamiya 74128 integrates easily into a basic hand tool kit. The 1.0mm shaft size ensures a firm grip for manual drilling and controlled rotation.

Can I use this bit on thin metal panels?

Yes, the Tamiya 74128 can handle thin metal sheets found in many RC kits, but use light pressure and support the material to avoid bending.

What hand tool gives the best control with this bit?

A pin vise offers the most precise feel for a 0.7mm tip, though a low speed micro drill with a collet that accepts a 1.0mm shaft will also work.

How can I reduce the risk of breaking the bit?

Use a steady, slow feed, back the bit out regularly to clear swarf, and support thin pieces with a sacrificial backing to avoid side loading the Tamiya 74128.
