• Note: All inserts are inspected to ISO Precision Standards. Please verify your tool holder's required I.C. dimension before purchasing to ensure 100% compatibility.

What Are Carbide Inserts Used For in Metal Turning?

Carbide inserts are ideal for turning, milling, drilling, boring, and grooving operations across a wide range of materials, including:

Our optimized carbide substrate and advanced nano-coating are designed to excel in:

Stainless Steel & Low Carbon Steel : Excellent for 304, 316, and A3 steel. Reduces work hardening and built-up edge (BUE).

General Steel Parts : High wear resistance for 45# steel, 40Cr, and alloy steels in high-speed continuous cutting.

Cast Iron: Exceptional thermal stability for processing gray cast iron and ductile iron (QT) with reduced vibration.

Hardened Steel & High-Hard Alloys : Engineered for Hard Turning (HRC 45-60). Ideal for hardened die steel and quenched parts.

Advantages of Carbide Inserts

• Nano-PVD/CVD Coating: Multi-layer coating technology provides a high thermal barrier, extending tool life by up to 35%.
• Standard ISO Precision: Manufactured to strict ISO tolerances. High repeatability ensures consistent dimensions from the first cut to the last.
• Optimized Chipbreaker: The specialized 3D geometry ensures smooth chip evacuation, preventing workpiece scratching and heat buildup.
• Universal Compatibility: Fits all standard STFCR/L, STUCR/L, and S-STFCR series boring bars and external tool holders.

Technical Specifications

Expert Machining Tips

• For Finishing: Use higher cutting speeds (Vc) and lower feed rates (f).
• For Roughing: Use lower speeds and higher feed rates with TCMT 08 radius inserts for maximum strength.
• Coolant: For stainless steel and hardened steel, constant coolant flow is recommended to prevent thermal cracking.
