What RPM is the machine there to be used on good and what type of cutting would you intend doing with them.
A general opinion would only be based on what someone else has used them for.
I feel unless you know what you will be doing with them anyone's opinion is really null and void.

That is pretty cheap. I don't have them but use similar cutters at work. You need a pretty rigid mill to use cutters like that successfully. I don't know what mill you have but i wouldn't use them in a hobby mill.

cva
My little CVA die sinking mill might handle those indexible cutters OK . From what I have read online: another CVA owner has written "it is a very rigid machine" It will spin up to 3000rpm in its standard configuration and I am fitting a higher HP motor to the CVA . Anyway 'Welder' who also has a CVA may comment on his experiences.

I have a 16mm one of those that I bought from CTC some years ago. It works OK for light cuts on a Hafpos HM52 at my max speed of 2400RPM. Doesn't leave a great finish but does remove metal. I figure that a pair of inserts are way cheaper than a 16mm HSS cutter.

I have a 16mm one... With my bridgeport clone max depth of cut is about 0.75mm.... After that it chatters...
Light red, the colour of choice for the discerning man.

I tried the 12mm holding it in ER collet but was very dissatis3ed. This was mainly because I didnt have enough preload in the mill spindle ,So after I fixed that problem, I went about work holding differently,I took the 25 mm cutter and.machined the end to MT3 and tapped it M 12. That worked better and I could take a 2.5 mm cut
