Korloy VCGT110304-AK H01 (ANSI VCGT 221-AK) Polished Aluminum Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy VCGT110304-AK H01 (ANSI Cross Reference: VCGT 221-AK) is the industry standard for High-Performance Aluminum Finishing. Engineered with a 35° diamond profile and a 7° relief angle, this insert offers maximum versatility across standard CNC tooling systems. The 0.4mm (0.016") corner radius provides the ideal balance of edge durability and surface brilliance, making it the primary choice for Aluminum Alloys, Brass, Copper, and Engineering Plastics.
Maximum Productivity: The VCGT110304 is designed to handle higher feed rates than the 0.2mm version without sacrificing surface quality. Its micro-polished rake face ensures a frictionless path for chips, effectively preventing the "welding" of gummy materials to the cutting edge.
Technical Specifications (Metric & ANSI):
| ISO Designation | VCGT 110304-AK |
| ANSI Designation | VCGT 221-AK |
| Inscribed Circle (IC) | 6.35 mm / (1/4") |
| Thickness (S) | 3.18 mm / (1/8") |
| Corner Radius (r) | 0.4 mm / (0.016") |
| Relief Angle | 7° (C-Type) |
| Grade | H01 (Micro-Polished Uncoated Carbide) |
Core Performance Benefits:
- Optimized Edge Strength: The 0.4mm radius is significantly more robust than R0.2, making it suitable for semi-finishing and handling slight cut interruptions.
- Universal Compatibility: The 7° relief angle is specifically designed to fit SVJCR and SVUCR series tool holders, the most common holders in precision CNC turning.
- AK "Aluminum Knight" Geometry: High rake angle for clean shearing, ensuring zero burrs on soft alloys and plastics.
- Mirror-Polish Surface: Achieves an exceptional high-gloss finish, reducing post-processing time and costs.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys (Wrought) | 300-1000 m/min | 0.10-0.25 mm/rev | 0.1-3.0 mm |
| Copper / Brass | 200-600 m/min | 0.08-0.20 mm/rev | 0.1-2.5 mm |
| Plastics (Delrin/POM) | 150-500 m/min | 0.12-0.30 mm/rev | 0.2-4.0 mm |
Compatible Tooling Systems (7° Relief):
Precision-matched for VCGT 1103 (ANSI 22) positive tool holders:
- External Turning: SVJCR 1212H11 / SVJCR 1616H11 / SVJCR 2020K11
- Boring Bars: S16Q-SVUCR11 / S20R-SVUCR11 / S25S-SVUCR11
Machinist Tip: Optimization Guide
Why VCGT110304 is the professional's choice:
This 0.4mm version is far more durable than the 0.2mm version. It is the perfect balance for shops that want one insert to handle both light roughing and final mirror-finish passes.
To achieve a mirror finish with an R0.4, maintain a stable, high surface speed. If the chips start to nest, increase the feed rate slightly to engage the AK chipbreaker's geometry.
Pro Advice: Always double-check your holder. If you are using an SVJBR (5° relief), you should use a VBGT insert. For the SVJCR (7° relief) in your turret right now, this VCGT is the correct match.
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.
