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.

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) |
|---|---|---|---|

| 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.
