The Original Korloy VBGT110302-AK H01 (ANSI Cross Reference: VBGT 220.5-AK) is a high-precision Polished Uncoated Carbide Insert designed for Mirror-Finish Performance. This 35° diamond profile insert is the industry benchmark for machining Aluminum Alloys, Copper, Brass, and Engineering Plastics. Featuring the micro-polished H01 grade and the razor-sharp AK (Aluminum Knight) chipbreaker, it ensures a surface finish that often eliminates the need for secondary polishing.
The Anti-Sticking Specialist: The H01 grade is a non-coated carbide with a mirror-polished rake face. This specialized texture prevents "Built-Up Edge" (BUE) — the primary cause of surface tearing in soft aluminum — ensuring consistent dimensional accuracy and a high-gloss aesthetic.
Technical Specifications (Metric & ANSI):
| ISO Designation | VBGT 110302-AK |
| ANSI Designation | VBGT 220.5-AK |
| Inscribed Circle (IC) | 6.35 mm / (1/4") |
| Thickness (S) | 3.18 mm / (1/8") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Relief Angle | 5° (B-Type) |
| Grade | H01 (Micro-Polished Uncoated Carbide) |
Core Performance Benefits:
- Ultra-Sharp AK Geometry: High rake angle provides a clean shearing action, ideal for preventing burrs on delicate aluminum or plastic parts.
- Exceptional 35° Versatility: The slim profile allows for intricate profiling, deep undercuts, and fine tracing where clearance is restricted.
- Superior Surface Ra: Micro-polished surface ensures sub-micron surface roughness on non-ferrous materials.
- High Heat Dissipation: The uncoated H01 grade dissipates heat rapidly, especially when paired with mist or flood coolant.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (Low Silicon) | 300-1000 m/min | 0.05-0.15 mm/rev | 0.05-2.0 mm |
| Copper / Brass | 200-600 m/min | 0.05-0.12 mm/rev | 0.05-1.5 mm |
| Plastics (Delrin/Acrylic) | 150-500 m/min | 0.08-0.20 mm/rev | 0.10-2.5 mm |
Compatible Tool Holders (5° Relief):
Precision-matched for VBGT 1103 (ANSI 22) positive inserts:
- External Profiling: SVJBR 1212H11 / SVJBR 1616H11 / SVJBR 2020K11
- Internal Boring Bars: S16Q-SVUBR11 / S20R-SVUBR11 / S25S-SVUBR11
Machinist Tip: Achieving Mirror Gloss
To maximize the "high-light" effect on aluminum:
H01 polished carbide performs best at high surface speeds. If the finish looks dull, increase your RPM. The AK chipbreaker creates a better chip at higher velocities.
Always use a B-type holder (SVJBR/SVUBR). Using a C-type holder (7° relief) with a VBGT insert can lead to improper clearance and vibration, ruining the high-gloss finish.
Pro Advice: The 0.2mm radius is perfect for fine detail, but if you have a high-volume job with more stock removal, consider switching to the VBGT110304-AK H01 for better tool life.
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.
