TCMT 110204F XP7120

Achieve flawless internal bores with the TCMT 110204F XP7120. This triangular, positive-clearance insert is engineered to provide maximum stability in delicate operations. By using a 7° relief angle, it reduces cutting forces significantly, making it the ideal solution for machining with long-overhang boring bars or on smaller lathes with lower rigidity.

The XP7120 Grade utilizes a high-performance CVD coating. This provides an incredibly hard, heat-resistant surface that protects the carbide substrate from crater wear during continuous high-speed cutting in carbon, alloy, and tool steels.

Key Features:

• (Medium-Finishing) Chipbreaker: Optimized for light-to-medium depths of cut. It ensures that chips are broken and evacuated efficiently from deep bores, preventing damage to the finished surface.

• Positive 60° Triangle Geometry: Offers three sharp cutting edges. The positive rake design is essential for preventing vibration and chatter, especially when boring into small diameters.

• 0.4mm Precision Radius: Perfect for finishing passes where tight dimensional tolerances and a high-quality surface finish (Ra) are required.

• Versatile Application: While specialized for steel (P) and cast iron (K), its sharp edge also performs well in some stainless applications when high precision is required.
