Help please gents,
I bought a job lot of 70+ milling cutters off the bay but cannot ID the mounting taper to try & buy an adaptor/chuck/collet to fit my little mini mill.
the dimensions are
large 13.4mm (17/32") - 11.66mm (29/64") machined length of taper 44mm (1 11/16")
Small 10.34mm (13/32") - 9.17mm (23/64") machined length of taper 32mm (1 3/16")
I did ask the seller before buying if they would suit my MT2-ER20 collet chuck, he said yes but obviously they don't,
I'd like to try & get an adaptor before I return them "not as described" but Need to know what the taper is, It's not Morse.
Well the most used is the Morse Taper.
There are many online charts of the dimension of the MT and also the Taper Calculation!
Good Luck,
Stuart
Here is the standards fore the Morse Taper from my Machinist Handbook....
MT# Taper per inch Socket openning
0 .05205" .3561"
1 .04988" .475"
2 .04995 .700"

Thanks Stuart, they're 100% Not Morse taper, I took a couple in to "Axminster tools" today & they're visibly different to Morse, shorter with a slightly steeper taper, they couldn't ID them,
They directed me to a former staff member who they said is "the all knowing oracle of machining" & he's also stumped,
so it looks like they'll get returned to the seller not as described.
So to hear that....
So It must some In-House made tooling for their milling machine.
Must be from a High End Milling Machine Maker... to have the tooling o make their own Tools!!

These look similar to reamers I used to use as an apprentice, matched to the machine for sure but I can't for the life of me remember name of it!
