Here is a flex shaft tip from @myjewellerygarden - “I use my @foredomelectric hand piece all the time but it kept turning & slipping in my hand while using it. This meant I had to keep adjusting on the go (not ideal) or stop and re-adjust (slows me down). “ That tape is so useful! Thanks for sharing with us!!
