I appreciate it......it took me a while to find the imfo I needed. I'm no machinist by no means, but I'm learning lil bit here and there. Forums are great to get all inputs.
I bought it as is condition and did not have the arbor and chuck. I'm just trying to figure the size of arbor. I measured the bottom end (23mm) . I want to say it's a MT3.
I appreciate the the reply......I work at a golf course, basically, I'm old school. Half the **** being made now you have to throw away or made out of plastic. Then there is stuff i modify.
