Precision Micro Drilling with Tamiya 74090

The Tamiya 74090 Fine Drill Bit gives modellers a tiny yet accurate 0.2mm cutting point for fine detailing. It is compatible with Tamiya Fine Pin Vises (74050 and 74051) and is useful for delicate assembly and detailing tasks.

Quality HSS for Small Jobs

Produced from High-Speed Steel, the Tamiya 74090 keeps a sharp profile for repeated delicate drilling in common modelling materials like plastic, wood and thin aluminium. Its build promotes dependable, clean holes.

Compact Geometry for Tight Work

The bit's 19.5mm overall length and 0.2mm diameter suit confined model positions where precision is crucial, such as pinning tiny parts or creating fine mounting points on scale builds.

What technique helps when drilling thin styrene?

Use a steady hand, low rotation speed and support the sheet beneath the cut. Feed the bit slowly and clear debris to prevent cracking or melting the edge.

How should I clean and maintain the bit?

Remove plastic or metal swarf with a fine brush and keep the bit dry. If sticky residue builds up, use a solvent on a cloth and ensure the bit is fully dry before storage.

Is this suitable for drilling bearing housings?

For light locating holes in thin bearing mounts it can be used, but for precision bearing bores you may prefer a reamer or a larger, more robust drill tailored to the bearing size.
