Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SP300 H01 is a premium 3.0mm Single-Ended Parting and Grooving Insert precision-engineered for Non-Ferrous Metals. Featuring the H01 Uncoated Carbide Grade, this insert is ultra-polished to a mirror finish. This sharp, high-rake design is essential for preventing built-up edges (BUE) when machining "gummy" materials like Aluminum, Brass, Copper, and various Plastics, ensuring a burr-free finish and superior dimensional accuracy.
The Mirror Finish Specialist: H01 grade features an extremely sharp cutting edge that slices through non-ferrous materials with minimal resistance. The polished top surface allows chips to slide away effortlessly, preventing heat build-up and surface scratches.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Cutting Width (W) | 3.0 mm (+/- 0.05mm) |
| Grade | H01 (Uncoated & Polished) |
| Material Suitability | Aluminum, Copper, Brass, Zinc, Plastic |
| Clamping | Single-Ended SP System |
Core Performance Benefits:
- Ultra-Sharp Cutting Edge: Minimizes cutting pressure and prevents burr formation, ideal for thin-walled aluminum tubes.
- Anti-Adhesion Polished Surface: The mirror-like rake face ensures that soft materials don't weld to the tool tip.
- High Speed Capability: Despite being uncoated, the micro-grain carbide maintains its edge at high RPMs required for non-ferrous turning.
- Zero Contamination: Since it is uncoated, there is no risk of coating flakes contaminating sensitive materials like medical-grade plastics or high-purity copper.
Recommended Cutting Parameters (Non-Ferrous):
| Material | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Aluminum Alloys (Low Silicon) | 200 - 600 m/min | 0.05 - 0.20 mm/rev |
| Brass / Copper | 150 - 400 m/min | 0.05 - 0.15 mm/rev |
| Plastics (Delrin/Nylon) | 100 - 300 m/min | 0.10 - 0.25 mm/rev |

Machinist Tip: Why H01 for Non-Ferrous?
Choosing between coated and uncoated inserts:
Sharpest Edge. Coating always slightly rounds the cutting edge. For Aluminum and Plastics, you need the absolute sharpest "knife-like" edge to prevent melting and tearing.
Heat Protection. These are for Steels and Stainless. Using these on Aluminum will result in material sticking to the tool (BUE) almost instantly.
Pro Advice: When machining aluminum, use high-speed mist or air blast to keep the chips moving. For a true mirror finish, ensure the insert center height is dead-on—even 0.02mm off can cause a "nub" in soft metals.
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.
