Detail Drilling for RC Builds

The Tamiya 74128 provides a precise 0.7mm bore and a 1.0mm shaft for consistent, small-diameter drilling. It is aimed at hobbyists who need tidy holes for mounting and assembly on scale models.

Recommended Uses

Use this micro bit for pilot holes, fastening tiny screws, and modifying small plastic or light metal components. Its size reduces the risk of splitting thin materials.

Tools and Tips

Fits most pin vises and manual micro drills that accept a 1.0mm shaft. For best results, drill at a slow, steady pace and back the bit out regularly to clear chips.

Will the Tamiya 74128 cut through plastic cleanly?

Yes, when used with light pressure the 0.7mm tip produces neat holes in most hobby plastics without cracking.

Can I use a power hand drill with this shaft size?

You can if the drill accepts a 1.0mm shaft, but keep speed low and hold the workpiece firmly to avoid chatter.

How do I avoid bending the bit?

Support small parts on a flat block, use gentle pressure, and do not apply side loads to the Tamiya 74128 to keep it straight.
