I'm looking to buy some 40mm insert face mills for roughing out some deep pockets in Aluminum on a new job we are starting. I want to go with a 90 deg insert. The deepest pocket is just under 8 inches (203.2mm).
I'm looking at buying either a Sandvik 40mm or a Ingersoll 40 mm. Any feed back on the performance on these two brands will be helpfull
