Description:

Korloy CCGT 09T308-AK / CCGT 32.52-AK H01 are premium-quality uncoated carbide inserts engineered for high-precision finishing and semi-finishing of non-ferrous metals. With a large nose radius of 0.8 mm, the 09T308 variant allows for higher feed rates and better surface finish on stable setups, making it ideal for aluminum and copper alloy machining.

Featuring the AK chipbreaker and H01 carbide grade, these inserts offer low cutting resistance, excellent chip control, and mirror-like surface finishes. The polished surface minimizes built-up edge, which is critical when machining soft and gummy materials.
