The cutter diameter is 25mm and Iscar call it an end mill and the insert makes it suitable for a (limited) face cutter. I don't use it as an end mill (in the true sense of an end mill).
The cutting oil also takes some of the heat away, and the cutting oil helps the finish on the steel the main reason I use it. If I could zip the speed up to plus 5000 rpm I'm sure the finish will be a lot better. I have to try to make the best of what I have and the cutting oil helps.
It is a normal practice in the home workshop with bench top mills to only use one or two inserts (in stead of all four). It does come down to the power required and in my case the lack of it, also the chip load per insert and the vibration plays a part. Another factor is I cut in conventional milling so the cutter is not used full face diameter but approx half at a time.
If someone wants to try using all four inserts then I would say try it see what happens then try two or one and then choose, see what suits your machine.
I've not damaged the empty pockets - it can't be easy Ken because I'm normally good at easy.
Ed, reduced the number of cutting inserts and found it was better so it worked for him as well.
At the time I bought this cutter with some inserts about 15 years ago this was all there was, maybe now there is better tooling for the home workshop. The tool I have was not really intended to be used on a bench type mill and I will bet money they never tested it to see how it would perform.
When I bought it from Iscar they were a little skeptical whether it work work satisfactory. A guy even came to my work shop to see if it would work, and that is why I always buy Iscar tooling and inserts.
As far as I know the dry cutting came from Industry because they wanted to get rid of the "mess" associated with fluids. As I understand the tooling companies do not say don't use cutting oil they say you can machine dry and if you want to use cutting oil use it from the start.
