The Original Korloy DCGT11T304-AK H01 (ANSI Standard: DCGT 32.51) is the industry standard for high-efficiency finishing of non-ferrous metals. Combining a 11mm cutting edge with a 0.4mm (1/64") nose radius, this insert offers the perfect balance between surface finish quality and edge durability. The AK (Aluminum Knight) chipbreaker features a mirror-polished rake face that prevents aluminum chips from welding to the tool, ensuring a superior, burr-free finish on Aluminum alloys, Copper, and high-performance Plastics.
High-Efficiency Finishing: The 0.4mm radius is the most versatile choice for non-ferrous turning, providing better heat dissipation and edge strength than smaller radii while still achieving exceptional surface gloss.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DCGT11T304-AK |
| ANSI Code | DCGT 32.51 |
| Grade | H01 (Micro-grain Uncoated Carbide) |
| Insert Finish | Mirror Polished |
Core Performance Benefits:
- Anti-Adhesion Design: Mirror-polished surfaces drastically reduce friction, making it nearly impossible for "gummy" materials like 6061 Aluminum to stick to the insert.
- Optimized Chip Control: The sharp rake angle of the AK chipbreaker ensures excellent chip evacuation even at low feed rates.
- Reduced Cutting Forces: Precision-ground sharp edges minimize part deflection, which is critical when machining thin-walled or slender non-ferrous parts.
- Broad Compatibility: Excellent for CNC turning of Aluminum, Brass, Bronze, Copper, and various engineering plastics like Delrin and Acrylic.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 400 - 1200 m/min | 0.10 - 0.30 mm/rev | 0.2 - 4.0 mm |
| Copper / Yellow Brass | 200 - 700 m/min | 0.08 - 0.25 mm/rev | 0.2 - 2.5 mm |
| Acrylic / Plastics | 150 - 600 m/min | 0.15 - 0.35 mm/rev | 0.5 - 5.0 mm |
Compatible Tool Holders:
Standard 55-degree diamond tool holders for 11T3 size:
- External Turning: SDJCR/L 1212 / 1616 / 2020K11
- Precision Boring: S16Q-SDUCR11 / S20R-SDUCR11 / S25S-SDUCR11
Selection Tip: R0.2 vs. R0.4 Radius
Choosing the right tip for your aluminum project:
The universal choice. Offers higher edge strength and faster feed rates. Best for general finishing and semi-finishing of larger surfaces.
Best for intricate details and very small diameters. It produces lower radial cutting forces, which is essential for ultra-thin parts or avoiding vibration.
Machinist's Pro Tip: For high-speed machining (HSM), ensure your machine's spindle balance is checked. The AK H01 geometry can handle incredible RPMs to achieve that perfect "mirror" effect.
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.
