Tool Holding

The two most common cutting tools you will use in the mini mill are drill bits and end mills. Drill bits are held in drill chucks, while end mills are held in collets or end mill holders.

Mini mills come with two types of spindles, R8 and 3 Morse taper. The most common mini mill spindle in the US and Canadian market is R8 however some brands in both countries sell mini mills that have 3 Morse taper spindles. Countries other than the US and Canada most commonly have 3 Morse taper spindles.

Morse taper collets R8 collets

A Morse taper has a continuous taper from one end to the other.

An R8 has a straight section with a 16.85° cone taper at the end.
