Hi
I used to have a Minilor TR1 lathe also known as Vario-lux 130. The spindle was bored to accept a collet type ESX25.
The FR1 milling attachment was bored to accept the same collets. For drilling a special ESX25 shaped collet was supplied which i think was bored MT1 to accept the drill chuck also used by the lathe tailstock.
regards
Steve
