I'm not sure that the actual shape has any effect on the finish, but the top geometry (chipbreaker) will, as will the grade.We have both the KENNAMETAL and WALTER catalogues and are these small !!! Seems like there' no other way but to sit and study these and make some sense out of all that technicality.
Carbide inserts love to work, so yes, you can definitely run them in the high range. If you buy an insert from a large manufacturer, there is sometimes information in their catalogue that will give you the recommended speeds and feed rates etc. I know that Walter has this information in their catalogues, as a good friend of mine keeps pointing it out to me
Carbide Depot has a look up function for chipbreakers and grades that will give you some information as to what they are suited to. Sometimes they don't have what you are looking for and it is always useful to look at the actual manufactures catalogue. Fortunately, most have pdf version on their web sites. I have several downloaded and refer to them when I am searching eBay for a bargain.
Personally, I stick to brand name inserts over the cheap Chinese ones.
Will remember that the geometry is more important than the profile when looking at some of these.
Yup, the Brand named ones do and will make matters a lot easier.
Thanks again
