Korloy TNMG160408-HS PC5300 (TNMG 332-HS) Universal Turning Insert for Steel & Stainless (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TNMG160408-HS PC5300 (ANSI: TNMG 332-HS) is a high-performance Universal PVD Coated Insert designed for versatility and precision. Featuring the legendary PC5300 Grade, this insert excels in Steel, Stainless Steel, and Cast Iron applications. The HS (High-Sharpness) chipbreaker, paired with a robust 0.8mm radius, provides the perfect balance between low cutting resistance and edge strength for semi-finishing to finishing operations.
The Shop-Favorite All-Rounder: If your workshop handles a variety of materials daily, the PC5300 is your most valuable asset. Its specialized sub-micron substrate and high-oxidation resistant PVD coating eliminate the need for frequent tool changes between different material batches, significantly boosting CNC productivity.
Technical Specifications (Metric & Imperial):
| ISO Designation | TNMG 160408-HS |
| ANSI Designation | TNMG 332-HS |
| Inscribed Circle (IC) | 9.525 mm / (3/8") |
| Thickness (S) | 4.76 mm / (3/16") |
| Corner Radius (r) | 0.8 mm / (1/32") |
| Grade | PC5300 (Premium Universal PVD) |
Core Performance Benefits:
- Broad Material Spectrum: Outstanding performance on Carbon Steel, Alloy Steel, 300/400 series Stainless, and Ductile Iron.
- HS Precision Geometry: A very sharp cutting edge that minimizes work hardening—crucial for stainless steel and thin-walled parts.
- Enhanced Edge Stability: The 0.8mm (332) radius offers better resistance to chipping and heat than the 0.4mm version, allowing for higher feed rates.
- Advanced PVD Nano-Coating: Superior lubricity reduces friction heat and prevents built-up edge (BUE) in gummy materials.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon & Alloy Steel | 140-260 m/min | 0.12-0.30 mm/rev | 0.5-3.0 mm |
| Stainless Steel (304/316) | 90-190 m/min | 0.10-0.25 mm/rev | 0.5-2.5 mm |
| Cast Iron (GG/GGG) | 110-210 m/min | 0.15-0.35 mm/rev | 0.8-3.0 mm |
Compatible Tooling Systems:
Fits all standard TNMG 16-size (3-size ANSI) negative holders:
- External Lathe Holders: MTJNR 2020K16 / MTJNR 2525M16 (ANSI 12-4B / 16-4D)
- Internal Boring Bars: S25S-WTJNR16 / S32T-WTJNR16
Machinist Tip: Why HS for General Purpose?
Selecting the right chipbreaker for PC5300:
Sharp & Clean. The HS chipbreaker is optimized for lower cutting forces. Use this when you need a superior surface finish or when machining long, slender parts that are prone to vibration/chatter.
Strong & Reliable. If you are doing bulk material removal or heavy roughing on steel, the HM geometry provides a stronger edge. But for versatility and finishing, HS is the superior choice.
Pro Advice: The 0.8mm radius is extremely durable. When machining stainless steel, ensure you maintain a steady feed rate to prevent the tool from dwelling, which causes the material to work-harden and reduces tool life.
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.
