I'm getting ready to order my first milling machine and need advice. Do i get mt3 or R8? It will be a bench top mill, not likely to ever buy another one. Working only in metric, on mostly mild steel and aluminium, with an occasional stainless steel item. Pros and cons please, I am absolutely clueless here. :zap: |

Being 'self releasing' an R8 taper results in less thumping to remove than an MT3 - can be quite a significant advantage. I used to have MT3 on a Mill/Drill a few years back and now have R8 on my Bridgeport - wouldn't want to go back to MT3. I do keep a set of R8 to Mt1,2,&3 adaptors for use with taper shank drills. |

Depends on the cost of tooling in your area. Here in the UK MT tooling seems more plentiful and is normally a little cheaper. It also has the advantage that you can put MT taper drill bits straight in the quill without compromising your "Z" clearance with adaptors. Some Morse taper machines are self extracting, and if not, it's not too difficult to make it so. In the US they seem to have stuck with R8 rather than progressing to ISO like most countries maybe because of it's use on Bridgeport mills and their clones, so R8 is far more popular than Morse Taper over there. There's also the advantage with morse that you can use the same tooling on both lathe and mill if they have the same taper or use a cheap adaptor. Apart from hobby machines Morse and R8 are only legacy tapers now found on old machines. Most new stuff have ISO tapers. |

I ended up with MT3 only because I didn't know that I could have the same machine with R8. But either is plentiful here in the UK. |

R8 would be my first choice John |
