Description:

Korloy CCGT 09T304-AK / CCGT 32.51-AK H01 are high-precision carbide inserts with a polished surface and extremely sharp cutting edge, designed for high-quality finishing of non-ferrous metals like aluminum, copper, and brass. Compared to 09T302, the 09T304 insert has a larger nose radius, which improves surface finish and allows slightly higher feed rates during stable finishing operations.

These inserts feature AK chipbreaker geometry with a positive rake angle that minimizes cutting forces and prevents material buildup. The uncoated H01 grade provides excellent wear resistance and surface finish in soft, ductile materials.

Key Features:

• Shape: CCGT (80° diamond), size 09T304 / 32.51 — suitable for deeper finishing and semi-finishing operations.

• AK chipbreaker: ultra-sharp and polished for optimal performance on aluminum and similar materials.

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

• Compatible with CNC and manual lathes requiring high surface quality.
