MT2 /R7

[Mathurin]

Hi!

Is there a difference between MT2 collet and R7 collet ?

Thanks

R7 ? or R8?

R7 collet Is it the same angle and diameter than the MT2 collet ?

Not even close . Here is a R 8 https://www.ebay.com/itm/R8-Collet-...074522?hash=item48a4b6955a:g:K8QAAOSwU4FaB8h4 Here is a MT 2 https://www.ebay.com/itm/7-Pc-2MT-R...332131?hash=item1a282f3523:g:XyQAAOSw32lY0dfr
Why do you ask ?

MT2 is a Taper, not a collet. Also I have searched for 2 hours now and have come up empty on an R7 collet. I've never heard of one. MeriTool hasn't got one listed???

"Billy G" whats up Bro ? I just bought a MT 2 collet set for my 6" Craftsman lathe , they are so dam cute . They take a 3/8-16 draw bar . https://www.ebay.com/itm/7-Pc-2MT-R...332131?hash=item1a282f3523:g:XyQAAOSw32lY0dfr
I looked for a R7 also I found a weird rubberized type collet for a tapping head but it had been discontinued .

Thanks for your research. I found that R7 or R8 are for milling machine and Mt series are for metal late

With all due respect, my mill has a MT2 taper spindle. I have a Clausing 8520 Mill.

My industro-lite M500 has MT3 horizontal and vertical tapers
