CNMG120404HQ CA515 (TAB00860)

The CNMG120404HQ CA515 is a high-speed finishing insert combining the sharp HQ chipbreaker with the proven CA515 CVD-coated carbide grade. The striking bright gold CVD coating — clearly visible in the image, with a distinctive star-pattern chipbreaker geometry around the insert — delivers outstanding wear resistance and thermal stability for continuous cutting in steel at elevated speeds. The small 0.4mm nose radius enables precise dimensioning and high surface quality in finishing passes.

Key Features

• Insert shape: C (80° diamond) — 2 cutting edges per insert
• Size: 12mm x 04mm thickness x 04 nose radius (0.4mm) — small nose radius for precision finishing
• Chipbreaker: HQ — sharp, positive geometry for clean chip breaking at medium-high feeds in finishing
• Grade: CA515 (CVD-coated carbide) — outstanding wear resistance for high-speed continuous turning in steel
• ISO application: P10–P25
• Edges: 2 cutting edges

Applications

Finishing and semi-finishing of carbon steel and alloy steel at medium to high cutting speeds. The 0.4mm nose radius and HQ chipbreaker combination delivers excellent surface finish and dimensional accuracy. Compatible with CNMG-style toolholders. Available in packs of 10.
