WCGT Carbide Inserts – Precision Cutting for Turning & Finishing

At CNC Tools Depot, we bring you a comprehensive selection of WCGT Carbide Inserts, sourced from leading global brands like Korloy, Widia, Kennametal, Taegutec, Mitsubishi, Iscar, and more. Designed for precision turning and finishing applications, WCGT inserts feature a trigon (80° diamond shape with positive geometry) that provides excellent chip control, sharp cutting edges, and reduced cutting resistance – making them ideal for high-performance CNC machining.


🔹 What are WCGT Inserts?

WCGT carbide inserts are trigon-shaped, positive rake inserts commonly used in finishing and semi-finishing turning operations. Their sharp cutting edge ensures smooth surface finish, while their optimized chip-breaking design improves tool life and reduces vibration.

These inserts are often used in low to medium cutting forces applications such as machining aluminum, stainless steel, and non-ferrous materials.


🔹 Applications of WCGT Inserts

WCGT inserts are widely used in:

  • Precision Turning: Achieves tight tolerances and superior surface quality.

  • Finishing Operations: Ideal for smooth finishes in steel, stainless steel, cast iron, and non-ferrous metals.

  • Aluminum Machining: Their sharp geometry makes them perfect for non-ferrous and soft metals.

  • Threading and Grooving Support: Can be adapted in certain threading operations depending on toolholder compatibility.

  • General CNC Turning: Suited for lathes, CNC turning centers, and high-speed machining.
