Korloy KNUX160405R-11 NC3030 Copy Turning Insert for Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy KNUX160405R-11 NC3030 is a specialized Copy Turning and Profiling Insert, renowned for its unique 55° parallelogram shape. This design allows the tool to reach into tight profiles and perform multi-directional turning that standard inserts cannot achieve. Optimized with the NC3030 CVD coating, this insert is built for Toughness and Impact Resistance, making it the primary choice for Carbon Steel, Alloy Steel, and rough-forged components where interrupted cutting is frequent.
The Profiling Expert: KNUX inserts are designed for versatility in copy turning. The -11 chipbreaker specifically targets medium-to-roughing operations, ensuring excellent chip evacuation even when the cutting depth varies drastically across a profile.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | KNUX160405R-11 |
| Hand of Tool | Right Hand (R) |
| Corner Radius | 0.5 mm |

Core Performance Benefits:
- Exceptional Edge Toughness: NC3030 grade is engineered with a high-toughness substrate that effectively prevents chipping during heavy-load or interrupted cutting.
- Optimized Profile Geometry: The unique shape of KNUX reduces tool pressure during back-turning, preventing vibration and ensuring better surface finishes.
- Excellent Thermal Stability: The thick CVD coating provides a heat shield for the carbide, extending tool life in dry or high-speed steel machining.
- Versatile Chip Breaking: The -11 chipbreaker is designed to handle wide fluctuations in depth of cut (Ap) during complex copy turning.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (Ap) |
|---|---|---|---|
| Carbon Steel | 140 - 250 m/min | 0.15 - 0.40 mm/rev | 1.0 - 4.5 mm |
| Alloy Steel | 120 - 220 m/min | 0.15 - 0.35 mm/rev | 1.0 - 4.0 mm |
| Interrupted Steel | 90 - 160 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.5 mm |
Compatible Tool Holders:
KNUX inserts require specific Profiling Tool Holders (CKJN style):
- External Profiling Holders: CKJNR 2020K16 / CKJNR 2525M16
The Copy Turning Logic: NC3030 vs. NC3020
Selecting the right grade for your KNUX profiling strategy:
The General Purpose & Toughness king. Choose this for unstable setups, roughing forged steel, or when the cut is interrupted.
The High-Speed Specialist. Best for continuous, stable cutting at higher RPMs. It offers better wear resistance but is more prone to fracture in rough conditions.
Machinist's Pro Tip: When profiling with KNUX160405R-11, ensure your lead angle is correct for back-turning. The 0.5mm radius is perfect for balancing surface finish with edge strength in heavy profiling passes.
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.
