The Original Korloy SNMG120404-HA H01 is a high-performance Double-Sided Square Turning Insert, specifically engineered for Aluminum (N-Group), Copper, and Non-Ferrous Metals. This insert combines the extreme economy of 8 cutting edges with the superior finish of the H01 Mirror-Polished Carbide. The -HA chipbreaker is designed with an extra-sharp rake angle to slice through soft, gummy materials effortlessly, ensuring a high-gloss surface and excellent dimensional control.
8-Edge Mirror Finish: Most aluminum inserts are single-sided (like CCGT or SCGT). The SNMG-HA series changes the game by offering 8 usable corners per insert, drastically reducing your tool cost per part without sacrificing the "Mirror Finish" quality your customers demand.

Core Performance Benefits:
- Ultra-Sharp Cutting Edge: Precision-ground to a razor edge to ensure clean shearing of aluminum fibers, preventing burrs.
- Mirror-Polished Rake Face: Reduces friction to the absolute minimum, allowing chips to slide off instantly without welding to the tool.
- Unbeatable Economy: 8 cutting edges provide the lowest cost-per-corner for aluminum turning in the market.
- Versatile Application: Perfect for 6061, 7075 aluminum, pure copper, brass, and industrial plastics.
Recommended Cutting Parameters (Aluminum):
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (Low Silicon) | 300 - 800 m/min | 0.05 - 0.25 mm/rev | 0.1 - 3.5 mm |
| Copper / Brass | 200 - 500 m/min | 0.05 - 0.20 mm/rev | 0.1 - 2.5 mm |
| Engineering Plastics | 200 - 600 m/min | 0.10 - 0.35 mm/rev | 0.5 - 4.5 mm |
Compatible Tool Holders:
Designed for negative ISO holders (must be high-precision for best results):
- External Turning: MSSNR 2020 / 2525 / 3232 Series
- Internal Boring Bars: S32T-MSSNR12 / S40U-MSSNR12
Machinist Tip: Why "HA" on a Negative Insert?
Understanding the SNMG-HA advantage for non-ferrous parts:
Shearing vs. Pushing. Traditional SNMG inserts push material (good for steel). The -HA chipbreaker is ground to a sharp angle that "shears" the material. This is why it works so well on aluminum despite being a negative (double-sided) insert.
The Cold Choice. Coatings like PVD often contain aluminum. In high-speed turning, this creates a chemical bond that leads to sticking. H01 remains chemically neutral, ensuring your aluminum stays on the part, not on the tool.
Pro Advice: For SNMG120404-HA, use high spindle speeds. Aluminum loves speed. If you see "built-up edge" (silver bumps on the tool tip), increase your RPM. The goal is to keep the cutting zone cool and the chips moving fast.
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.
