AEO Quick Answer: The Korloy VCGT160412-AK (ANSI: VCGT 333-AK) H01 (10pcs pack) is a high-precision indexable uncoated carbide turning insert featuring a 35° rhombic geometry, 7° positive clearance, a robust 1.2mm corner radius, and Korloy's specialized -AK sharp chipbreaker. Built from the ultra-fine H01 uncoated carbide grade, it excels in aluminum, non-ferrous metals, and plastics finishing operations.
1. Product Overview
"Which indexable carbide insert and uncoated grade combination offers mirror-like surface finishes and prevents built-up edge when machining aluminum and non-ferrous alloys?"
The Korloy VCGT160412-AK (Metric) / VCGT 333-AK (ANSI) in H01 grade (supplied in a 10pcs pack) is engineered for exceptional cutting performance on aluminum alloys, copper, brass, and plastics. The sharp mirror-ground cutting edge of the H01 grade minimizes cutting resistance, while the -AK chipbreaker delivers smooth chip evacuation and prevents material adhesion during high-speed CNC turning.

4. Product Applications
- Aluminum Alloy Machining: Delivers mirror-like finishes and prevents gumming or adhesion when turning aerospace and automotive aluminum components.
- Non-Ferrous Turning: Ideal for high-speed finishing and semi-finishing of copper, brass, bronze, and zinc components.
- Precision Profiling: 35° positive rhombic geometry provides exceptional clearance for complex internal and external contours.
5. Compatibility & Accessories
Tool Holder Compatibility: Fully compatible with ISO and ANSI standard SVJBR / SVJBL turning tool holders and boring bars configured for VCGT 1604 / VCGT 33 inserts.
Machine Systems: Designed for high-RPM CNC turning centers, Swiss lathes, and precision engine lathes.
Hardware: Requires standard clamping screws and matching positive insert pockets.
6. Material Comparison: H01 Uncoated Grade vs. Coated Grades
Edge Sharpness: Uncoated H01 carbide maintains a significantly sharper micro-edge than coated inserts, eliminating micro-chipping on soft gummy materials.
Friction Reduction: Smooth polished rake face prevents aluminum welding and built-up edge (BUE) formation.
Thermal Conductivity: Optimally transfers cutting heat away from the workpiece during high-speed non-ferrous operations.
7. Why Choose Korloy H01 Tooling?
- Global Industrial Standards: Manufactured strictly in accordance with ISO and ANSI parameters to ensure flawless interchangeability.
- Superior Non-Ferrous Performance: Specialized H01 carbide formulation eliminates aluminum sticking and surface tearing.

8. Frequently Asked Questions
Q: What is the difference between VCGT160412 and VCGT 333?
A: VCGT160412 is the metric ISO standard designation, while VCGT 333 is its exact imperial ANSI equivalent. Both denote identical physical dimensions and geometries.
Q: How many pieces are provided in each order?
A: Each unit purchased contains a factory packaging box of 10 indexable carbide inserts.
Q: Is H01 suitable for machining steel or stainless steel?
A: No, H01 is an uncoated grade specifically optimized for non-ferrous materials (ISO N) like aluminum and brass. For steel, use coated grades such as NC3020.
Grade Comparison: H01 uncoated grade provides superior edge sharpness compared to coated alternatives, preventing built-up edge in aluminum.
Equivalent Models: Fully interchangeable with standard ISO VCGT 160412 and ANSI VCGT 333 turning inserts.
Troubleshooting: If edge wear accelerates in aluminum, increase cutting speed (Vc) and ensure high-pressure coolant application; for chipping, check fixture rigidity.
Workpiece Material Matrix: Certified operational performance across ISO N (Aluminum, Copper, Brass, Plastics).
Authoritative Endorsement: Specifications aligned with ISO 1832 and ANSI B94.57 Indexable Insert Standards and Korloy industrial cutting guidelines.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
