The Tamiya Conical File (74164) is a tapered round needle file designed for enlarging holes, cleaning up injection mould points, and working in circular cavities on plastic model parts. The conical shape allows it to work progressively — inserting further increases the effective diameter — making it ideal for precisely sizing holes for gun barrels, tubing, and wheel hubs. An extremely useful file shape that complements flat and triangular profiles.
