I seem to have standardized on two styles of inserts.
DCMT / DCGT 55 Deg with 7 Deg Positive Relief Angle
CCMT / CCGT 80 Deg with 7 Deg Positive Relief Angle
These seem to give the best all around clearance and I have straight, left and right tool holders along with boring bars that use these. The M100 DEX Holders al use the same size insert, 21.51 regardless of shank size so it makes insert buying much simpler. Get some --M- for Steel and --G- for plastics, and non-ferrous metals.
Lesser used is the WCMT 80 Deg Trigon Inserts, again with 7 Deg Positive Relief Angle.
HSS Blanks are rarely used and only if all else fails.
