The Original Korloy DNMG150408-HA H01 (ANSI Standard: DNMG 432) is a premium 55° diamond insert designed for High-Performance turning of Aluminum and Non-Ferrous alloys. Featuring a robust 0.8mm nose radius, this insert offers the perfect balance between edge strength and surface quality. The H01 Grade is an uncoated, ultra-fine micrograin carbide that undergoes a specialized peripheral grinding process to achieve a razor-sharp edge. Combined with the mirror-polished HA chipbreaker, it effectively prevents "Built-up Edge" (BUE) and delivers a high-gloss finish on even the softest aluminum grades.
Efficiency & Surface Quality: The R0.8 geometry allows for higher feed rates without sacrificing the "mirror" effect, making it ideal for automotive, aerospace, and consumer electronics parts where cycle time and aesthetics are equally important.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DNMG150408-HA |
| ANSI Code | DNMG 432 |
| Grade | H01 (Polished Uncoated Carbide) |
| Nose Radius | 0.8 mm (Enhanced Security) |
Core Performance Benefits:
- Up-Sharp Precision Edge: Fully ground periphery provides a significantly sharper cutting action than standard molded inserts, reducing horsepower requirements.
- Anti-Adhesion Polished Top: The mirror-like HA flute allows chips to flow freely, eliminating the "smearing" effect on aluminum surfaces.
- Exceptional Tool Life: High-purity micrograin carbide maintains a sharp edge even in high-speed, continuous cutting applications.
- Multi-Material Versatility: Also performs excellently on Copper, Brass, Bronze, and high-density Plastics (Delrin, Peek).
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 250 - 900 m/min | 0.10 - 0.35 mm/rev | 0.2 - 4.0 mm |
| Copper / Yellow Brass | 150 - 450 m/min | 0.08 - 0.25 mm/rev | 0.2 - 2.5 mm |
| Technical Plastics | 200 - 600 m/min | 0.15 - 0.40 mm/rev | 0.5 - 5.0 mm |
Compatible Tool Holders:
Standard fit for all 55-degree negative DNMG tool posts:
- External Turning: DDJNR/L 2020K15 / 2525M15 / 3232P15
- Boring Bars: S25S-DDUNR15 / S32T-DDUNR15 / S40U-DDUNR15
The Aluminum Professional: R0.8 vs. R0.4
Both use the H01 polished grade, but the radius changes your production strategy:
Best for Productivity & Strength. The 0.8mm radius is more durable and allows for faster feed rates while still maintaining a high-quality finish. Ideal for general aluminum turning.
Best for Precision & Detail. The 0.4mm radius reduces radial cutting forces even further, making it the choice for thin-walled parts or sharp internal corners.
Machinist's Pro Tip: To achieve a true mirror finish on aluminum, use a high concentration of water-soluble coolant and the highest stable spindle speed. The H01 polished surface thrives in high-velocity environments!
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.
