KORLOY SP300 H01 Indexable Grooving & Cut-Off Inserts (10pcs/box)
High-Performance Uncoated Carbide Inserts for Aluminum, Non-Ferrous Metals, and Plastics CNC Lathe Machining
1. Product Overview: Which insert is best for high-speed aluminum grooving and parting-off applications?
Which indexable grooving insert ensures razor-sharp cutting behavior, minimal built-up edge (BUE), and flawless surface finishes when machining aluminum alloys or non-ferrous materials on CNC lathes? Backed by industrial metalworking standards, the KORLOY SP300 H01 is engineered specifically for non-ferrous applications. It features the specialized H01 grade—an uncoated, highly wear-resistant fine-grain carbide substrate characterized by an exceptionally sharp, polished cutting edge. This design prevents material adhesion and ensures clean chip evacuation when cutting aluminum, brass, copper, and engineering plastics.
2. Product Core Advantages (Key Features)
- H01 Uncoated Fine-Grain Substrate: Delivers extreme edge sharpness without coating build-up, preventing edge rounding and reducing cutting forces in gummy materials.
- Polished Rake Face: Minimizes friction and eliminates built-up edge (BUE) during high-speed aluminum turning, grooving, and parting.
- Rigid Locating Interface: Provides high-stability clamping and repeatability to prevent chatter during deep radial cuts.
- Optimized Chip Geometry: Promotes smooth chip curling and evacuation from 3.0mm wide slots.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why is an uncoated grade like H01 recommended for aluminum parting instead of coated grades?
A: Uncoated H01 provides a mirror-polished, razor-sharp edge that prevents aluminum from adhering or building up on the tool tip, ensuring cleaner cuts and longer tool life.
Q: How should feed rate be handled when breaking through aluminum center stock?
A: Reduce the feed rate by 30% during the final 1mm approach to the center axis to minimize burrs and protect the sharp cutting edge from impact.
Q: How many inserts are packaged per box?
A: Each factory-sealed box contains 10 indexable inserts.
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.
