The Original Korloy SCGT09T304-AK H01 is a premium Square ($7^\circ$ Positive) Turning Insert, widely recognized as the industry standard for machining Aluminum and Non-Ferrous Metals. Featuring the legendary H01 Grade, this insert is un-coated and features a mirror-polished rake face. This design effectively eliminates "Built-Up Edge" (BUE), allowing for exceptionally smooth chip flow and a high-gloss, mirror-like surface finish on the workpiece.
Ultimate Sharpness: The -AK chipbreaker is ground to a razor edge. Unlike coated inserts that can be slightly rounded by the coating process, the H01 grade provides the sharpest possible shearing action, critical for prevent "smearing" on soft aluminum alloys.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SCGT09T304-AK |
| Inscribed Circle (IC) | 9.525 mm |
| Thickness / Corner Radius | 3.97 mm / 0.4 mm |

Core Performance Benefits:
- Anti-Adhesion Polishing: The mirror-like top surface prevents aluminum chips from welding to the insert, extending tool life and surface quality.
- High-Speed Capability: Optimized for high SFM (Surface Feet per Minute) in non-ferrous materials.
- Versatile Application: Excellent for Aluminum (6061, 7075), Copper, Brass, Acrylic, and Wood.
- True Precision: Peripheral ground design ensures high repeatability when indexing the insert.

Machinist Tip: H01 vs. Coated Inserts
Why H01 is the gold standard for non-ferrous work:
Sharpest Edge Possible. Because there is no coating layer (which usually rounds the edge by a few microns), H01 can engage the material at much lower depths of cut without "pushing."
Steel & Stainless Experts. Grades like PC5300 are great for heat resistance but will cause aluminum to "stick" to the tip, leading to rough finishes and dimensional errors.
Pro Advice: When using SCGT09T304-AK H01, higher cutting speeds (Vc) generally yield better finishes. In aluminum, don't be afraid to push the RPM to its limit while using a light feed for that "chrome-like" result.
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.
