I just got a used 3 Axis CNC Mill today, it came with a bunch of tooling including a collet chuck but no collets. Im not sure which collets to get, the only markings on the tool are Lyndex N4007-1000. I was looking at the ER collets but there a re few different numbers ER-11, ER-16 etc.... Anyone know how I can find out wich collets this holder takes?

Thanks,
Jim

Look in your Weekly tool flyer or your tool supply book. The er series collets are listed in their respective capacities and for which tool holder [32,16] etc. they are made for.

HI
Just looked it up on the web I think it takes TG100 collets.
