Some time ago I bought this Japanese made boring head. I don't even know if it is complete or how to use it properly. Specifically, does it require a tool holder? Or can I simply put a 6mm HSS bit in etc. I have a number of questions I hope perhaps someone can help answer.
This is the boring head.
It has a Morse no 3 taper. There is a set screw that appears to be there to hold the tool(on the left seen from the side on the photo). It has an inch scale that spans 0.1in in 0.02 increments. It has words "Made in Japan" written as well as 2in 2in7/8ths marking (it can be rotated 13 times so 7/8ths on an inch is a likely range). Also it has a logo I identified as belonging to Mitsui Seiki.
More pictures below:
What makes me wonder how to use it that it's tool slot is an unusual shape (6 by slightly under 12mm or 0.236x0.470 in) and the internal feature visible on the photo above that pushes the tool out is very narrow and made from soft metal (unhardened) so if makes me think it is not supposed to push against high speed steel bit.
If anyone knows more about this tool or one like it, please let me know.
