The Original Korloy SCGT09T308-AK H01 is a premium Square ($7^\circ$ Positive) Turning Insert designed for high-efficiency machining of Aluminum, Copper, and Non-Ferrous Alloys. Featuring a robust 0.8mm Corner Radius, this model provides superior edge strength and allows for higher feed rates compared to the 0.4mm version. The H01 Grade is an un-coated, mirror-polished carbide that eliminates "Built-Up Edge" (BUE), ensuring consistent dimensional accuracy and a brilliant surface finish.
High Efficiency & Strength: The R0.8 radius on the SCGT09T308 is the perfect balance for machinists who need to remove material quickly while maintaining the ultra-smooth, polished results that the Korloy -AK geometry is famous for.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SCGT09T308-AK |
| Corner Radius | 0.8 mm (Increased Edge Strength) |
| Thickness / Inscribed Circle | 3.97 mm / 9.525 mm |
| Grade | H01 (Micro-Grain Mirror Polished) |
Core Performance Benefits:
- Reduced Tool Pressure: The -AK geometry's positive rake angle ensures the tool "cuts" rather than "pushes," even with the larger 0.8mm radius.
- Anti-Stick Performance: The mirror-polished rake face prevents soft aluminum from welding to the edge, a common cause of tool failure.
- Enhanced Feed Rates: The R0.8 radius allows for 50-80% higher feed rates than R0.4 while still achieving excellent surface finishes.
- Wide Material Versatility: Ideal for 6061/7075 Aluminum, Pure Copper, Brass, Wood, and Thermo-plastics.

Machinist Tip: Why R0.8 over R0.4?
Choosing the right radius for your aluminum project:
Best for Roughing & High Feed. The 0.8mm radius is much harder to chip. Use this if your workpiece has an uneven surface or if you want to decrease cycle times by pushing the feed rate.
Best for Fine Finishing. The 0.4mm radius is ideal for very thin-walled parts where you need to minimize radial cutting forces to prevent part vibration or deflection.
Pro Advice: When using SCGT09T308-AK H01, ensure your setup is rigid. While the R0.8 radius is stronger, it generates slightly more radial pressure. For high-speed aluminum turning, use a high-quality water-soluble coolant to keep the chip temperature low and the mirror finish perfect.
Packaging: 10 pieces per box.
