hi all, ive just registered to the forum

i do a little machining with work but nothing huge

recently a bought a job lot off tools, i knew what a lot of it was but im having trouble with a final bit

i think its a quick release collet tapping set up but im not entirely sure

the markings are as follows:

large main part/chuck

bison s3
mt4-c
m14-m33

the 3 collet sets

m22 16x12.5
m24 18x14.5
m27 20x16

ive googled it to to death but drawn a blank

thank you in advance and i hope someone can shed some light

Correct.
MT4 taper with a capacity of M14 to M33 and the three tap holders are for M22, M24 and M27 possibly a tad to big for 6BA :smile:
