When cutting a thread or using a Heli-coil Repair kit i always had the same problem. What size of drill bit to use?
Look up the right size in the internet. Look for the drill bit, find out it was lost, drive to Makiling lumber to buy a replacement, find out they don’t have that size, order it from Germany…. With these little tool rolls i just made this should be a thing of the past.
