The Tamiya Fine Engraving Bit 0.5mm (74138) is a 0.5mm scribing bit for use with the Tamiya Engraving Blade Holder (74139). The 0.5mm size produces wider, more visible panel lines — suitable for larger-scale models (1/35 vehicles, 1/32 aircraft) where finer lines can be too subtle, or for rescribing lines where additional width is required.
Diameter: 0.5mm
