Drill Bits

A #68 wire gauge size Jobber drill bit (diameter = 0.031" = 0.787 mm) can be useful for loading & packing powder inside the standard 11-BM mail-in 0.8 mm Kapton tubes

These small diameter drill bits cost $2 or less, and can easily be purchased online. If you intend to use it frequently, you might consider also purchasing a small pin vise (Starrett makes good ones) to more easily hold the small bit.
