The Original Korloy DCGT070202-AK H01 (ANSI Standard: DCGT 21.50.5) is a high-precision turning insert specifically engineered for non-ferrous materials such as Aluminum alloys, Copper, Brass, and high-performance Plastics. The AK chipbreaker features a mirror-polished rake surface that drastically reduces friction, preventing "Built-Up Edge" (BUE) and chip welding. With its razor-sharp periphery-ground edge and the H01 uncoated micro-grain substrate, this insert is the gold standard for achieving a mirror-like surface finish on small, intricate components.
Precision Finishing: The 0.2mm nose radius (R0.2) allows for incredibly fine detail and sharp corners, making it the preferred choice for electronic components, aerospace fittings, and medical device manufacturing.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DCGT070202-AK |
| ANSI Code | DCGT 21.50.5 |
| Grade | H01 (Uncoated Micro-grain Carbide) |
| Surface Treatment | Mirror Polished (preventing adhesion) |
Core Performance Benefits:
- Anti-Sticking Technology: The polished AK geometry ensures smooth chip flow, crucial for "gummy" materials like Aluminum 6061 or pure Copper.
- Razor Sharp Edge: Extremely low cutting forces prevent part deflection, making it ideal for thin-walled or small-diameter workpieces.
- Extreme Surface Quality: Capable of achieving Ra 0.4 - 0.8 surface roughness depending on machine stability.
- Versatile Application: Excels not only in Aluminum but also in Acrylics, Nylon, and other non-abrasive plastics.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloy (Si < 12%) | 200 - 800 m/min | 0.05 - 0.15 mm/rev | 0.1 - 2.0 mm |
| Copper / Brass | 150 - 500 m/min | 0.05 - 0.12 mm/rev | 0.1 - 1.5 mm |
| Plastics (Acrylic/Nylon) | 100 - 400 m/min | 0.08 - 0.20 mm/rev | 0.2 - 3.0 mm |
Compatible Tool Holders:
This insert fits any standard 55° Diamond SDJC or SDUC holder:
- External Holders: SDJCR/L 0808 / 1010 / 1212F07
- Boring Bars: S08K-SDUCR07 / S10K-SDUCR07
Pro Tip: Why choose H01 Uncoated?
Selecting the right edge for non-ferrous turning:
Offers the sharpest possible edge. Coatings actually "round over" the edge at a microscopic level, so uncoated H01 is better for ultra-fine finishes and soft materials.
Best for High-Silicon Aluminum (castings). The Diamond-Like Carbon coating provides the hardness needed to resist the abrasive sand particles in the alloy.
Note: Always use high-pressure coolant if possible when machining Aluminum to help with chip evacuation and heat control.
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.
