- Excellent heat resistance (800–1000°C)
- High compressive strength for intermittent cutting
Cost per edge: An insert gives 4–16 cutting edges for the price of one brazed or solid carbide tool. In production, cost per part drops 60–90 %.
Ultra-hard materials possible: PCD (10 000 HV) and CBN (4500 HV) cannot be made into solid end mills or brazed tips at reasonable cost — only as small inserts.
30-second tool changes: Index or flip the insert instead of regrinding or re-brazing (which takes 10–30 minutes).
Consistent performance: Every new edge has identical geometry and coating; no regrind variations.
Higher speeds & feeds: Modern coated carbide, ceramic, and diamond inserts run 3–10× faster than HSS or old brazed tools.
Flexibility: Same toolholder accepts roughing, finishing, aluminum, or hardened-steel inserts in seconds.
