I think I want to buy some of the modular tooling but I haven't been able to find any cutting data on the system. Any one know where to look?

Basically I am cutting 3.5" deep in 1018 steel. I was thinking of getting the 16mm head with the long Mount. I am 2 days into this with the 1/2" carbide that I have and I am not half done the job yet and I am going to need new tools soon.

Any information will greatly be appreciated.

thanks,

Chris
