Description
CARBIDE TURNING INSERTS RNMG
RNMG carbide turning inserts are single-sided, negative-geometry round inserts featuring a 0° relief (clearance) angle. These inserts are designed for medium-duty and general turning operations, offering high wear resistance, effective chip control, and stable performance under moderate cutting conditions. They are suitable for a variety of materials, including steel, cast iron, and non-ferrous alloys.
Made from cemented carbide (WC-Co) and often CVD or PVD coated (TiN, TiCN, Al₂O₃, TiAlN), RNMG inserts combine edge strength, chip control, and versatility, ensuring reliable performance in general turning applications.

Materials & Applications
RNMG carbide inserts are ideal for operations requiring stable performance, efficient chip control, and wear resistance under moderate cutting loads. The negative geometry ensures vibration resistance and edge stability during machining.
Typical Workpiece Materials:
• Steel (carbon and alloy) — general turning and medium-duty operations
• Cast Iron — suitable for medium-duty cutting
• Non-Ferrous Metals (Aluminum, Copper, Brass) — uncoated or polished-edge versions provide smooth cutting
Common Operations:
• Medium-duty roughing and general turning
• Light to medium cuts with consistent chip evacuation
• Internal and external turning requiring stable performance
