Korloy VCGT160402-AK H01 (ANSI VCGT 330.5-AK) Polished Aluminum Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy VCGT160402-AK H01 (ANSI Cross Reference: VCGT 330.5-AK) is a high-performance Large-Format Polished Carbide Insert designed for Ultra-Precision Finishing. With its substantial 16-size substrate, it offers superior rigidity for machining large-diameter non-ferrous components. The 7° relief angle ensures compatibility with common industrial tool holders, while the 0.2mm (0.008") radius and H01 Grade deliver a flawless mirror finish on Aluminum, Copper, and Engineering Plastics.
Stability Meets Precision: The 1604 series (4.76mm thickness) is the professional's choice for deep profiling where a thinner insert might deflect. Its micro-polished surface prevents material "welding" or built-up edge (BUE), which is essential for maintaining aesthetic gloss on premium aluminum alloys.
Technical Specifications (Metric & ANSI):
| ISO Designation | VCGT 160402-AK |
| ANSI Designation | VCGT 330.5-AK |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |

Core Performance Benefits:
- Maximum Profile Detail: R0.2 enables extremely sharp internal corners and fine intricate details on large aerospace or automotive parts.
- Rigid 16-Size Body: Handles higher surface speeds and cutting forces than the 11-size, reducing vibration during long-reach boring.
- Universal 7° Clearance: Perfectly matches SVJCR and SVUCR tool holders, the standard for professional CNC lathe turrets.
- Sub-Micron Surface Ra: Micro-polished H01 grade produces a high-gloss finish that often eliminates the need for secondary polishing.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 350-1100 m/min | 0.05-0.12 mm/rev | 0.05-2.0 mm |
| Copper / Brass | 200-650 m/min | 0.05-0.10 mm/rev | 0.05-1.5 mm |
| Engineering Plastics | 150-500 m/min | 0.08-0.20 mm/rev | 0.10-3.0 mm |
Compatible Tool Holders (7° Relief):
Designed for VCGT 1604 (ANSI 33) positive tooling systems:

- Heavy-Duty Boring Bars: S25S-SVUCR16 / S32T-SVUCR16
Machinist Tip: The 16-Size Secret
Pro-level advice for the VCGT 330.5-AK:
When using a 16-size insert with an R0.2 radius, you have a massive amount of tool support behind a very sharp tip. This is perfect for long-overhang boring where vibration usually ruins the finish.
Because VCGT has a 7° relief, it is more forgiving in small-diameter bores than VBGT. However, always ensure your chip evacuation (coolant flow) is high to prevent re-cutting chips.
Pro Advice: If you are machining 6061-T6 aluminum, the H01 grade will give you a "chrome" look if you keep your surface speed (Vc) above 600 m/min.

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.
