Is there a document somewhere that explains how determine which inserts a Sandvik endmill uses? I have a RA215.44-25MN25-09C and I can't seem to figure out which inserts fit. I see inserts that start with R215.44 online but is it that simple? Do all R215.44-* inserts fit tools that start with RA215.44? I emailed Sandvik a week ago with no response and they don't list a phone number. I'm in Alaska so we don't have local tool dealers to call.
