Description:

Korloy CCGT 060208-AK / CCGT 21.52-AK H01 are high-precision carbide inserts with a polished finish and ultra-sharp cutting edges, specifically designed for finishing non-ferrous metals such as aluminum, copper, and brass. With larger dimensions than the 060204 version, this insert allows for deeper finishing passes while maintaining a smooth surface and excellent chip control.

The AK chipbreaker geometry and uncoated H01 carbide grade ensure reduced cutting forces, extended tool life, and mirror-like surface finishes in soft materials.

Key Features:

• Geometry: CCGT (80° diamond shape) with 060208 size — suitable for deeper finishing operations.

• AK chipbreaker: polished, positive rake angle for low cutting resistance and reduced material adhesion.

• Grade H01: uncoated tungsten carbide with high hardness, optimized for non-ferrous materials.

• Ideal for CNC lathes and precision turning where excellent surface finish is critical.

⸻

Recommended Materials:

Perfect for aluminum and aluminum alloys, copper, brass, bronze, and some plastics or composites. Not suitable for steel or cast iron applications.
