Hello all. I'm finally getting my CNC machine back up and running. I'm looking to do some fairly large projects for myself soon, in regards to re-creating my spoiler / vacuum hold down plate. It's currently made out of MDF, but I am going to upgrade that to a delrin one with built in threads for hold downs. What I'm confused about is how to spec out threadmill cutters. I want to create, and thread holes of 4mm , 6mm, and 8mm in size. I ordered one off of Amazon, and that end is super tiny. The model is a Micro 100 TM-100-8 Any help with some specs to look for would be greatly appreciated. My spindle has 1/8" and 1/4" collets.
