What the AI looks for in Turning Inserts

Shape vs operation: C (80°) is general purpose. W (trigon) and S (square) are strong roughing shapes. D (55°) is for facing and profiling. T (triangle) suits light machines and holders. Larger nose angles give stronger edges. Smaller angles give more reach.
Nose radius vs depth of cut: Keep depth of cut at least about two-thirds of the nose radius. Use 0.4 mm for finishing, 0.8 mm for general work and 1.2 mm for roughing. Below that depth the chipbreaker does not engage and the insert rubs or makes stringy chips.
Negative vs positive: Use negative double-sided inserts (CNMG, DNMG, WNMG) on rigid production lathes. Use positive inserts such as CCMT 060204 and CCMT 09T304 on hobby and benchtop lathes. Small lathes lack the power and rigidity that negative rake needs.
Grade and coating: Use CVD grades for continuous steel and cast iron, PVD or cermet for stainless and finishing, and polished uncoated inserts for aluminum. Matching heat resistance and edge sharpness to the material sets tool life.
Holder code match: The holder's ISO code (for example MCLNR 2020K12) encodes clamping, shape, lead angle, clearance and insert size. The insert must match these. Clearance and size mismatches prevent proper seating.

Yes, they are the inch and metric designations of the same insert size and nose radius.
