Description
CARBIDE TURNING INSERTS RCMT
RCMT carbide turning inserts are single-sided, positive-geometry inserts featuring a round (R) shape with a 7° relief (clearance) angle. These inserts are designed for finishing, semi-finishing, and precision turning operations, providing excellent surface finish, chip control, and low cutting forces. They are suitable for a variety of materials, including steel, stainless steel, cast iron, and non-ferrous alloys.
Made from cemented carbide (WC-Co) and often PVD-coated (TiN, TiAlN, TiCN, or AlTiN), RCMT inserts offer a combination of precision, wear resistance, and low cutting forces, ensuring reliable performance in light to medium-duty turning applications.

Materials & Applications
RCMT carbide inserts are ideal for operations requiring smooth surface finishes, low cutting forces, and consistent performance. Their positive geometry ensures easy chip flow and reduced power consumption, making them suitable for delicate or precise components.
Typical Workpiece Materials:
• Steel (carbon and alloy) — finishing and semi-finishing
• Stainless Steel — PVD-coated grades resist heat and built-up edge formation
• Cast Iron — suitable for fine finishing operations
• Non-Ferrous Metals (Aluminum, Copper, Brass) — uncoated or polished-edge versions provide smooth cutting
Common Operations:
• Finishing and semi-finishing
• Profiling and contour turning
• Light to medium turning with consistent chip evacuation
• Internal and external turning requiring high-quality surface finish

Advantages & Performance
• Excellent Surface Finish: Sharp cutting edge and optimized chipbreaker design ensure smooth, high-quality surfaces
• Low Cutting Forces: Positive geometry reduces energy requirements and cutting heat
• Edge Stability: Micro-grain carbide substrate provides wear resistance even in precise finishing conditions
• Versatile: Compatible with multiple materials and standard ISO holders
• Durable and Reliable: PVD coatings extend tool life and maintain performance at medium speeds and moderate feeds
