I have a Tool Changer, Model 80-381, that was made by Tapmatic, Costa
Mesa, CA. It is also marked JAHRL, Orebro, Sweden. It has an R-8 shank
and the head is a quick change for collets which thread into tool head
and are held by ball detent and centered with a taper. The 1/2" end
mill holder is marked JAHRL 80-381-H1/2" . The short collet holder
is marked JAHRL 80-381-CH 10. Anyone know if these are still
supported or have any information about this tool system?
