Accurate 0.2mm Holes with Tamiya 74090

The Tamiya 74090 Fine Drill Bit is tailored to modellers who need fine, repeatable holes. It fits Tamiya Fine Pin Vises (models 74050 and 74051) and produces a precise 0.2mm bore ideal for small fixtures and detailing.

High-Speed Steel for Consistent Cuts

Made from HSS, the Tamiya 74090 resists dulling and gives reliable performance across materials such as modelling plastics, timber and thin aluminium sheet. The bit holds its edge to support tidy drilling sessions.

Small Format for Precision Tasks

The 19.5mm overall length combined with the 0.2mm tip makes this bit suited to tight areas and miniature assemblies where control and accuracy are essential.

Are spare bits widely available?

Spare micro bits are commonly sold individually or in small packs; look for HSS 0.2mm replacements from reputable hobby suppliers if you need extras.

Can I use this for drill-and-tap operations?

For tapping, ensure the hole diameter matches the tap requirements and proceed slowly; the tiny 0.2mm size is mainly for locating pins or light fixtures, not heavy threaded holes.

Best practise to extend bit life?

Run at low speeds, back out often to clear chips and avoid forcing the bit. Store bits safely and swap out if you notice any bend or dulling.
