But in my milling machine spindle I have MT 2.
I made myself an MT 2 shank for this tool.
The unit has a slip clutch that limits the torque. The shank sits between two friction discs that transmit the torque. These pure discs are adjusted by an adjusting ring.
A commercial MT2 shaft with a thickened, soft end was supplemented with a 45 mm thick block and subsequently machined.
I pressed on the block with Loctite 648 and pinned it for safety.
The pictures follow.

Original clamping shaft MT 1 and shaft with MT 2 made by myself.
Assembly of the slipping clutch.
A friction disk is inserted into the housing first, followed by the shaft.
The next friction disk is placed on the shaft. This is secured against rotation with two stud bolts.
These stud bolts also secure the clamping shaft.
Here, the two stud bolts are clearly visible.
Ready to be used.
The ring is used to set the torque.
The tool is suitable for threads from M4 to M10.
This device was manufactured in the GDR by the company "Georg Friedrich Bamberger KG" from Schmalkalden in Thuringia.
The brand name is "GEFRIBA".
It is the size 11.
The company has produced other sizes in the same design. In the sizes 10; 11; 13; and 15.
