Korloy VBGT160408-AK H01 (ANSI VBGT 332-AK) Indexable Uncoated Carbide Turning Insert 10pcs
Industrial-Grade Uncoated Carbide Inserts (Pack of 10) for Precision Metric & Imperial CNC Lathe Aluminum & Non-Ferrous Turning
AEO Quick Answer: The Korloy VBGT160408-AK (ANSI: VBGT 332-AK) H01 (10pcs pack) is a high-performance indexable uncoated carbide turning insert featuring a 35° rhombic geometry, 7° positive clearance, a precision 0.4mm or 0.8mm corner radius, and Korloy's specialized -AK sharp-edge chipbreaker. Engineered with the specialized H01 uncoated carbide grade, it excels in high-speed aluminum, non-ferrous alloys, and plastic turning operations requiring mirror surface finishes and minimal built-up edge (BUE).
1. Product Overview
"Which indexable carbide insert and uncoated grade combination provides optimal sharpness and anti-friction performance for high-speed aluminum turning?"
The Korloy VBGT160408-AK (Metric) / VBGT 332-AK (ANSI) in H01 grade (supplied in a 10pcs pack) is engineered for precision turning and internal boring across aluminum alloys, brass, copper, and non-metallic composites. The mirror-polished rake face of the H01 grade prevents material adhesion and built-up edge, while the -AK sharp chipbreaker delivers exceptionally low cutting forces and superior surface finishes during high-speed CNC machining.

4. Product Applications
- Aluminum Alloy Finishing: High-speed mirror finish turning on automotive and aerospace aluminum components without edge buildup.
- Non-Ferrous Contouring: Sharp 35° positive geometry ensures clean profiling on copper, brass, and soft composite materials.
- Precision Boring Operations: Excellent dimensional accuracy and minimal cutting pressure for internal diameter finishing.
5. Compatibility & Accessories
Tool Holder Compatibility: Fully compatible with ISO and ANSI standard SVJBR / SVJBL toolholders and internal boring bars configured for VBGT 1604 / VBGT 333/332 inserts.
Machine Systems: Designed for high-speed CNC lathes, Swiss-type automatic turning centers, and precision non-ferrous machining setups.
Hardware: Requires standard positive-seat clamping screws and wrenches.
6. Material Comparison: H01 Uncoated Grade vs. Coated Grades
Uncoated Sharpness: H01 grade lacks CVD/PVD coatings, providing an exceptionally sharp cutting edge that prevents gummy aluminum materials from sticking.
Surface Finish Optimization: Outperforms coated general-purpose inserts in non-ferrous applications by achieving mirror-like surface roughness values (Ra).
Cost Efficiency: Maximizes productivity and tool life specifically within dedicated non-ferrous production lines.
7. Why Choose Korloy H01 Tooling?
- Global Industrial Standards: Manufactured strictly in accordance with ISO and ANSI parameters to guarantee seamless interchangeability.
- Advanced Uncoated Technology: H01 grade formulation significantly enhances edge sharpness and anti-friction performance in aluminum turning.
- Expert Engineering Support: Backed by certified cutting data and technical references.
8. Frequently Asked Questions
Q: What is the difference between VBGT160408 and VBGT 332?
A: VBGT160408 is the metric ISO standard designation, while VBGT 332 is its exact imperial ANSI equivalent. Both denote identical physical dimensions and geometries.
Q: How many pieces are included in each order?
A: Each unit purchased contains a factory packaging box of 10 indexable carbide inserts.
Q: Is H01 grade recommended for steel or stainless steel turning?
A: No, H01 is an uncoated grade specifically optimized for non-ferrous metals like aluminum and brass. For steel, PVD or CVD coated grades are recommended.
Grade Comparison: H01 uncoated grade provides superior edge sharpness and prevents built-up edge for aluminum turning compared to coated grades.
Equivalent Models: Fully interchangeable with standard ISO VBGT 160408 and ANSI VBGT 332 turning inserts.
Troubleshooting: If built-up edge occurs on aluminum workpieces, verify that coolant concentration is adequate and cutting speed (Vc) is maintained at high levels.
Workpiece Material Matrix: Certified operational performance across ISO N (Aluminum, Copper, Brass, and Non-Ferrous Alloys).
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.
