Stumbled over Link removed see CofC seller and was blown away by the choice. Despite the obvious diameter/angle differences, why would you choose one of these styles over the other? I'm particularly interested in the rectangle (APMT) vs triangle (TCMT) variants. Edited By JasonB on 24/11/2020 20:12:29

It is a WNT and the single sided positive insert sits in a holder that pivots around the central hole in the insert. SAU also make the same type. Some use triangular inserts, and some square ones.
