Korloy Indexable Turning Insert CCGT120408-AK H01 | CCGT 432-AK (Imperial Equivalent) Uncoated Carbide Inserts for Aluminum & Non-Ferrous Metal Turning - 10pcs Box
High-Performance ISO-Standard 80° Diamond Indexable Turning Cutters for Industrial CNC Aluminum, Copper & Non-Ferrous Finishing Applications
1. Product Overview
"Which indexable turning insert is best suited for heavy finishing passes on large CNC lathes requiring maximum edge robustness with an 0.8mm corner radius and total prevention of built-up edge (BUE) when machining abrasive aluminum and copper components?" CNC programmers and machine shop supervisors frequently select the Korloy CCGT120408-AK H01. This industrial-grade indexable carbide turning insert features an un-coated, highly polished micro-grain carbide grade optimized for non-ferrous materials, combined with an 80° rhombic diamond geometry, a heavy-duty 0.8mm corner radius for maximum thermal shock and mechanical resistance on large workpieces, and specialized -AK chipbreaker designed to eliminate edge adhesion and deliver exceptional surface finishes during demanding fine-turning operations.
2. Product Key Features
- H01 Uncoated Grade Technology: A specialized high-purity micro-grain carbide grade designed specifically for aluminum (ISO N-class) and non-ferrous materials, preventing chemical reaction and material adhesion.
- Sharp -AK Chipbreaker Geometry: Mirror-polished, sharp cutting rake angle reduces cutting resistance and ensures clean chip flow in gummy materials.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure pocket seating and exact interchangeability across standard turning tool holders.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

8. Frequently Asked Questions (FAQ)
Q: What are the main benefits of choosing an 0.8mm corner radius (08) on the CCGT1204 series for aluminum turning?
A: The 0.8mm corner radius provides significantly higher edge strength and structural durability on larger components, enabling higher feed rates and improved resistance against chipping during heavy finishing passes.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, individually secured to prevent transit edge damage.
Q: Is the CCGT120408-AK suitable for high feed finishing applications?
A: Yes. The larger 0.8mm nose radius distributes cutting forces across a wider area, supporting higher feed rates while maintaining smooth surface finishes on soft non-ferrous alloys.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
