Ketan: Thanks for the notes on inserts. The more I look at it the more I'm put off buying. I've been looking at inserts from Cutwel made by Korloy. They seem to measure insert length in a slightly different way so it's hard to compare like with like. Even in the Arc calalogue the length and width of the two inserts on offer are different. How does that work in the machined pocket?
Cutwel do inserts that almost exactly match the Arc part numbers, but are specifically for the Korloy Alpha Mill series. They also do ISO standard inserts. In this section the inserts are stated to be generic but the part numbers differ from Arc in the detail. Specifically what is the significance of the PDFR and PDER parts after the style and size code?
I apologise for being a pain but as always in engineering the devil is in the detail and I don't want to waste my money!
