Korloy VCGT160412-AK H01 (ANSI VCGT 333-AK) Polished Aluminum Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy VCGT160412-AK H01 (ANSI Cross Reference: VCGT 333-AK) is the most powerful 7° Relief Polished Carbide Insert in the V-style family. Engineered for Maximum Material Removal Rate (MRR), the 1604 (3/8" IC) substrate provides immense rigidity. The massive 1.2mm (3/64") corner radius ensures unmatched edge toughness, allowing for extreme feed rates and stable performance in interrupted cuts or scaly cast aluminum surfaces.
Ultimate Edge Strength: The R1.2 (VCGT 333) geometry is built to withstand heavy radial forces. It is the go-to choice for large-scale aluminum projects where tool failure is not an option and where you need to move a lot of material quickly while maintaining a polished Ra finish.
Technical Specifications (Metric & ANSI):
| ISO Designation | VCGT 160412-AK |
| ANSI Designation | VCGT 333-AK |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |

| Relief Angle | 7° (C-Type) |
| Grade | H01 (Micro-Polished Uncoated Carbide) |
Core Performance Benefits:
- Maximum Edge Reliability: The large 1.2mm radius is nearly impervious to chipping, making it perfect for roughing passes on forged or cast aluminum parts.
- High-Feed Capability: Allows for significantly higher feed rates (up to 0.45 mm/rev) than smaller radius inserts, maximizing machine uptime.
- H01 Mirror Surface: Micro-polished finish prevents gummy aluminum from sticking to the rake face, ensuring clean chip flow even at high depths of cut.
- Versatile 35° Profile: Despite its strength, the slim profile still allows for complex contouring and accessibility in tight areas.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys (6k/7k) | 300-1000 m/min | 0.15-0.45 mm/rev | 0.5-5.0 mm |
| Cast Aluminum (High Si) | 150-700 m/min | 0.12-0.35 mm/rev | 0.5-4.5 mm |
| Copper & Brass | 150-600 m/min | 0.10-0.30 mm/rev | 0.3-3.5 mm |

Machinist Tip: The R1.2 Advantage
When to choose VCGT 333-AK over smaller radii:
If you are turning aluminum parts with cross-holes or irregular surfaces, the 1.2mm radius provides the mechanical strength needed to survive the impacts that would snap an R0.2 or R0.4 tip.
To get the most out of the H01 mirror finish with such a large radius, ensure your machine can maintain high RPM. A large radius creates more tool pressure, so machine rigidity is essential to avoid chatter.
Pro Advice: The R1.2 radius is exceptional for creating smooth fillets and large radii in the corners of large aluminum housings.
Packaging: 10 pieces per box.

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.
