The Original Korloy DNMG150404-HA H01 (ANSI Standard: DNMG 431) is an industry-leading 55° diamond insert specifically engineered for High-Mirror Finishing of Aluminum, Copper, and Non-Ferrous Metals. Unlike coated inserts that can be "blunt," the H01 Grade is an uncoated, ultra-fine micrograin carbide that is fully ground and polished. The HA chipbreaker features a high rake angle and a mirror-polished top face, effectively eliminating material welding and ensuring exceptionally clean chip evacuation even on soft, gummy aluminum alloys.
Mirror Finish Performance: The H01 grade is optimized for high-speed cutting where surface aesthetics are critical. It is the go-to solution for automotive wheels, aerospace components, and decorative aluminum parts where a "buffed" look is required directly from the lathe.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DNMG150404-HA |
| ANSI Code | DNMG 431 |
| Grade | H01 (Uncoated Polished Carbide) |
| Application | Aluminum, Copper, Brass, Plastics |
Core Performance Benefits:
- Up-Sharp Precision Edge: Fully ground periphery provides a much sharper edge than molded inserts, reducing cutting force and heat.
- Mirror-Polished HA Groove: Prevents built-up edge (BUE) by allowing chips to slide effortlessly over the insert surface.
- Ultra-Fine Micrograin Substrate: High wear resistance even without a coating, maintaining edge sharpness for longer periods in non-ferrous materials.
- Small 0.4mm Radius: Ideal for intricate details and reducing vibration on thin-walled aluminum tubes or housings.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (Wrought/Cast) | 300 - 800 m/min | 0.05 - 0.20 mm/rev | 0.1 - 2.5 mm |
| Copper / Brass | 150 - 400 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.5 mm |
| Plastics / PVC | 200 - 500 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |
Compatible Tool Holders:
Fits standard 55-degree negative DNMG tool posts:
- External Turning: DDJNR/L 2020K15 / 2525M15
- Boring Bars: S25S-DDUNR15 / S32T-DDUNR15
The "Mirror" Choice: H01 vs. PC9030
Why using the correct grade for aluminum is a game-changer:
Uncoated and razor-sharp. Best for Aluminum & Copper. The polished surface prevents soft metal from sticking to the tool, which is the #1 cause of poor surface finish.
Designed for Stainless Steel. While great for steel, the coating can actually cause aluminum to "smear" or stick, resulting in a dull, torn surface finish.
Machinist's Pro Tip: When using the H01 grade on aluminum, increase your RPM (Spindle Speed) as much as your machine allows. Higher speeds with this polished insert will yield a significantly brighter 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.
