Korloy CNMG120404-HA H01 Aluminum Turning Insert, Polished (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy CNMG120404-HA H01 (ANSI Standard: CNMG 431) is a high-precision, un-coated carbide insert specifically designed for Aluminum, Copper, and Non-Ferrous Metals. The H01 grade features an ultra-fine substrate with a specialized mirror-polished surface, which significantly reduces friction and prevents aluminum from welding to the cutting edge. Combined with the HA chipbreaker—known for its extremely sharp rake angle—this insert provides superior chip control and a brilliant surface finish.
Aluminum Specialist: The mirror-like finish and razor-sharp edge are essential for high-speed aluminum machining, ensuring zero built-up edge and exceptional part accuracy.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CNMG120404-HA |
| ANSI Code | CNMG 431 |
| Grade | H01 (Polished Uncoated Carbide) |
| Application | Aluminum, Brass, Copper, Plastics |
Core Performance Benefits:
- Mirror-Polished Surface: Minimizes friction, allowing chips to slide off instantly, which is critical for preventing "sticking" in soft metals.
- Razor Sharp Edge: The HA geometry shears through material with minimal pressure, reducing heat and chatter on thin-walled parts.
- Exceptional Toughness: Despite its sharpness, the H01 substrate maintains high edge strength for reliable long-term performance.
- Precision Finishing: The 0.4mm (1/64") radius allows for intricate details and high-quality finishes on complex CNC components.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Wrought Aluminum | 400 - 1000 m/min | 0.10 - 0.35 mm/rev | 0.2 - 4.0 mm |
| Cast Aluminum (Si < 12%) | 300 - 800 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.5 mm |
| Copper / Brass | 200 - 500 m/min | 0.10 - 0.25 mm/rev | 0.2 - 3.0 mm |
Compatible Tool Holders:
Aluminum machining requires high spindle speeds. Ensure your D-Type or M-Type holders are balanced:
- External Turning: PCLNR/L 2020K12 / PCLNR/L 2525M12
- Internal Boring Bars: S25S-PCLNR12 / S32T-PCLNR12
Machinist's Tip: H01 vs. DLC Coating
Choosing the right tool for Non-Ferrous materials:
Best for General Aluminum. The mirror polish is highly effective for most 6061/7075 aluminum jobs with excellent cost-performance.
Best for High-Silicon Aluminum. Choose DLC if you are machining extremely abrasive cast aluminum with high silicon content for even longer tool life.
Pro Tip: When machining aluminum, high cutting speeds (Vc) are your friend. Faster speeds combined with the H01 mirror finish will result in a much brighter surface finish.
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.
