The Original Korloy VBGT160402-AK H01 (ANSI Cross Reference: VBGT 330.5-AK) represents the pinnacle of Large-Scale Precision Finishing for non-ferrous materials. Utilizing the substantial 16-size substrate, this insert offers significantly higher rigidity and heat dissipation than smaller 11-size versions. The ultra-sharp AK (Aluminum Knight) chipbreaker, combined with the micro-polished H01 Grade, delivers a "shaving" action that produces a mirror-like surface on Aluminum, Copper, Brass, and high-performance Plastics.
Rigidity for Perfection: The VBGT 1604 series (4.76mm thickness) is designed for applications where tool pressure must be minimized but stability is paramount. The mirror-polished rake face ensures that even in deep profiling cuts, the material will not weld to the tip, maintaining a flawless Ra value throughout the production run.
Technical Specifications (Metric & ANSI):
| ISO Designation | VBGT 160402-AK |
| ANSI Designation | VBGT 330.5-AK |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Relief Angle | 5° (B-Type) |
| Grade | H01 (Uncoated Mirror-Polished Carbide) |
Core Performance Benefits:
- Maximum Accuracy: The 0.2mm radius enables incredibly sharp corners and fine contouring on large-diameter aerospace and automotive aluminum parts.
- Enhanced Rigidity: The 1604 (ANSI 33) footprint handles higher cutting forces without deflection, improving dimensional consistency.
- Burr-Free Cutting: Precision-ground peripheral edges provide a shearing cut, essential for thin-walled components and gummy non-ferrous alloys.
- 35° Design: Offers the best clearance for intricate profiling and secondary operations on multi-tasking CNC machines.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Wrought Aluminum (6061/7075) | 350-1200 m/min | 0.05-0.15 mm/rev | 0.05-2.5 mm |
| Pure Copper / Brass | 200-700 m/min | 0.05-0.12 mm/rev | 0.05-2.0 mm |
| Hard Plastics (PEEK/POM) | 150-600 m/min | 0.10-0.25 mm/rev | 0.15-3.5 mm |
Compatible Tool Holders (5° Relief Angle):
Precision-matched for VBGT 1604 (ANSI 33) positive inserts:
- Heavy-Duty External Profiling: SVJBR 2020K16 / SVJBR 2525M16
- Large Internal Boring Bars: S25S-SVUBR16 / S32T-SVUBR16
Machinist Tip: High-Speed Precision
Optimizing the VBGT160402-AK H01 performance:
Because the 16-size (3/8" IC) is much more stable than the 11-size, you can run at higher speeds (Vc) without vibration. Maximize your RPM to ensure the AK chipbreaker clears chips instantly.
Always verify your holder is an SVJBR/SVUBR (5° relief). Using an SVJCR holder (7° relief) will cause the insert to sit incorrectly, leading to poor surface quality and potential edge breakage.
Pro Advice: For internal boring, use a carbide-shank boring bar with this 1604 insert. The extra thickness of the insert prevents deflection in long-reach applications, ensuring a perfect mirror finish even deep inside a bore.

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.
