Korloy VBGT160408-AK H01 (ANSI VBGT 332-AK) Polished Aluminum Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy VBGT160408-AK H01 (ANSI Cross Reference: VBGT 332-AK) is an Extra-Durable Polished Carbide Insert engineered for High-Productivity Turning in non-ferrous materials. As the largest and strongest in the VBGT series, the 1604 substrate provides exceptional vibration resistance. The 0.8mm (1/32") corner radius is the most robust edge available, allowing for higher feed rates and increased tool life while still maintaining the signature H01 Grade mirror-finish on Aluminum, Copper, and Brass.
Maximize Your Feed Rate: The 0.8mm radius (VBGT 332) allows for significantly faster cycle times compared to the 0.4mm version. It distributes cutting heat over a wider area, preventing premature edge wear and ensuring stable production on large-diameter workpieces.

Core Performance Benefits:
- Maximum Edge Toughness: R0.8 provides the highest resistance to edge chipping in the VBGT family, ideal for slightly interrupted cuts in castings.
- High Surface Quality: Even with a larger radius, the AK chipbreaker and polished rake face ensure a bright, burr-free finish.
- Productivity Focused: Designed to handle depths of cut up to 4.5mm and aggressive feed rates, reducing overall cycle time.
- Thermal Security: The 1604 thickness dissipates heat effectively during prolonged cutting cycles on large aluminum housings.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Wrought Aluminum | 300-1100 m/min | 0.12-0.35 mm/rev | 0.2-4.5 mm |
| Cast Aluminum (Si < 12%) | 200-800 m/min | 0.10-0.30 mm/rev | 0.2-4.0 mm |
| Copper Alloys / Brass | 150-600 m/min | 0.08-0.25 mm/rev | 0.2-3.0 mm |

Machinist Tip: Why R0.8 for Aluminum?
Strategic advice for the VBGT 332-AK:
On large-diameter parts, the 0.8mm radius provides much better tool life. However, if you experience vibration on thin-walled parts, ensure your feed rate is high enough to fully engage the chipbreaker.
To get the best finish with an 0.8mm radius, use a spindle speed at the higher end of the range. The H01 polished surface thrives on high Surface Feet per Minute (SFM).
Pro Advice: The VBGT160408-AK is the best choice for rough-to-finish operations in one pass on many aluminum components. It has the strength to rough and the polish to finish.

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.
