When using very fine drill bits (0,5 – 0,2mm) I find it difficult to fix them firmly into my pin vise. I am using the Tamiya product, described to be used down to 0,1 mm drills.
In fact it starts to get difficult with diameters of 0,5mm to fix the bits properly. I tried oiling the threads, or using pliers to apply more power, but neither helps.
Can anyone recommend a trick or better apted tool?
