So Kennametal has discontinued their A3 deep grooving line(pic below)................I have been using them for a long time. The groove inserts actually breaks a chip even in the gummiest aluminum ..................no long stringers or curly cues.................I bought one of their new Beyond Evolution holders and inserts..............all I get is curly cues and rats nests...................the old inserts have a nice bump that turns the chips into tiny little granules.............very easy to deal with. What's out there similar to the A3's?
