That is, the taper shank of the drill bit corresponds to the taper hole of the variable diameter sleeve

2) Determine the required thread specification for the end of the reducer sleeve, using M12 for metric purposes × 1.75, the English version is 7/16-20UNF

What is the difference between the R8 reducing sleeve and the R8 milling cutter intermediate sleeve?

Answer: The variable diameter sleeve is used to fit the taper shank drill bit; The middle sleeve of the milling cutter is used to fit the taper shank milling cutter, and the middle sleeve of the milling cutter does not have metric or English functions
