The Original Korloy VCGT160408-AK H01 (ANSI Cross Reference: VCGT 332-AK) is the most robust 7° Relief Polished Carbide Insert in the 35° diamond family. Specifically engineered for High-Productivity Turning, the 1604 (3/8" IC) footprint ensures maximum thermal stability and vibration resistance. The 0.8mm (1/32") corner radius allows for aggressive feed rates and increased depth of cut, delivering a mirror-like finish on Aluminum, Copper, and Brass while significantly reducing cycle times.
Built for Strength: The R0.8 edge geometry is the strongest available for VCGT inserts. It is ideal for machining large components where tool life is critical, or for applications involving slightly interrupted cuts and abrasive high-silicon aluminum alloys.
Technical Specifications (Metric & ANSI):
| ISO Designation | VCGT 160408-AK |
| ANSI Designation | VCGT 332-AK |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |
| Corner Radius (r) | 0.8 mm / (0.031") |
| Relief Angle | 7° (C-Type) |
| Grade | H01 (Micro-Polished Uncoated Carbide) |
Core Performance Benefits:
- Extreme Productivity: High-strength R0.8 radius enables feed rates up to 0.35 mm/rev, drastically improving production throughput.
- Maximum Edge Security: The large radius dissipates heat more effectively and resists micro-chipping in heavy-duty profiling.
- Universal Compatibility: The 7° relief fits the common SVJCR and SVUCR tool holder series found in most CNC shops.
- Non-Stick Performance: Mirror-polished H01 grade prevents material buildup, maintaining high-gloss Ra values even in deep cuts.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Wrought Aluminum (6k/7k) | 350-1100 m/min | 0.12-0.35 mm/rev | 0.2-4.0 mm |
| Cast Aluminum (Si < 12%) | 200-800 m/min | 0.10-0.30 mm/rev | 0.2-3.5 mm |
| Copper / Brass | 150-600 m/min | 0.08-0.25 mm/rev | 0.2-3.0 mm |
Compatible Tooling Systems (7° Relief):
Precision-matched for VCGT 1604 (ANSI 33) tool holders:
- External Profile Tooling: SVJCR 2020K16 / SVJCR 2525M16
- Internal Boring Bars: S32T-SVUCR16 / S40U-SVUCR16
Machinist Tip: The Productivity Powerhouse
Optimizing the VCGT 332-AK:
The 0.8mm radius is strong enough to handle light roughing and stable enough to finish. On many large aluminum parts, you can achieve the required Ra finish in one final pass with this insert.
When boring large diameters (32mm+), the VCGT160408 is superior. The 7° relief angle prevents rear-end rubbing in the bore, and the R0.8 radius ensures the tip stays cool during long travel.
Pro Advice: If you are getting vibration on long, thin parts, switch back to an R0.4 (VCGT160404) to reduce the tool pressure. Otherwise, keep the R0.8 for maximum speed.
Packaging: 10 pieces per box.
