Korloy VNMG160408-HA H01 (ANSI VNMG 332-HA) Polished Insert for Aluminum & Non-Ferrous Metals (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy VNMG160408-HA H01 (ANSI Cross Reference: VNMG 332-HA) is a high-productivity 35° Rhombic Negative Insert specifically engineered for Non-Ferrous Materials. By utilizing an uncoated, ultra-fine grain carbide with a Mirror-Polished Rake Face, this insert minimizes friction and heat generation. The 0.8mm (1/32") Corner Radius provides superior edge strength, allowing for significantly higher feed rates and deeper cuts in Aluminum, Copper, and Brass without sacrificing the signature high-gloss finish of the H01 grade.
Superior Edge Integrity: The R0.8 radius design provides a robust cutting tip that excels in medium-duty turning and semi-finishing. Its increased contact area helps dissipate heat faster, extending tool life during high-volume aluminum production.
Technical Specifications (Metric & ANSI):
| ISO Designation | VNMG 160408-HA |
| ANSI Designation | VNMG 332-HA |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |
| Corner Radius (r) | 0.8 mm / (1/32") |
| Grade | H01 (Mirror Polished Uncoated) |
| Primary Materials | Aluminum, Copper, Brass, Bronze, Plastics (N) |
Core Performance Benefits:
- Enhanced Surface Quality: The mirror-polished rake face eliminates chip welding and built-up edge (BUE), resulting in a "smear-free" reflective finish on aluminum workpieces.
- High-Feed Capability: The R0.8 corner radius allows for faster cycle times by supporting higher feed rates (up to 0.30 mm/rev) while maintaining structural edge security.
- Optimized HA Chipbreaker: Features a sharp positive rake angle and a wide flute design to manage long, stringy aluminum chips efficiently.
- Versatile Application: While optimized for aluminum, it performs exceptionally well on other soft non-ferrous metals and engineering plastics like Nylon and PEEK.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 300 - 1000 m/min | 0.10 - 0.35 mm/rev | 0.5 - 4.0 mm |
| Brass / Bronze | 200 - 600 m/min | 0.10 - 0.25 mm/rev | 0.5 - 3.0 mm |
Compatible Tool Holders:
- External Turning: MVJNR / MVVNN / DVLNR Series (Size 16)
- Internal Boring Bars: S32U-MVQNR16 / S40V-MVUNR16 (Right-hand)
Pro Tip: Why R0.8 for Aluminum?
The 0.8mm radius allows for much higher feed rates than the 0.4mm version. In large aluminum components, this can reduce cycle times by up to 40% while still achieving an excellent Ra value.
When cutting at depth, the R0.8 radius creates a thicker chip that is easier for the HA breaker to curl and snap, preventing the dreaded "long ribbon" chips that can scratch your part.
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.
