The Original Korloy SNMG120404-HS PC5300 is a versatile Double-Sided Square Turning Insert engineered for stability and precision. Known as the "Problem Solver" in the machine shop, the PC5300 PVD Grade is famous for its exceptional toughness and resistance to chipping, even under heavy interrupted cuts. The -HS (High-Sharpness) chipbreaker is specifically designed to provide low cutting force and superior chip control in semi-finishing operations across multiple material groups.
Maximum Versatility: PC5300 is Korloy's most popular PVD grade because it handles everything—from Carbon Steel and Stainless Steel to Cast Iron and Heat Resistant Alloys. If your machining setup is unstable or your cut is interrupted, this is the safest insert choice.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | SNMG120404-HS |
| Corner Radius | 0.4 mm (High Precision) |
| Chipbreaker | -HS (Sharp Edge / Semi-Finishing) |
| Grade | PC5300 (Premium Universal PVD) |
Core Performance Benefits:
- Excellent Chipping Resistance: The ultra-fine carbide substrate and advanced PVD coating make this insert nearly immune to premature edge failure during shocks.
- Precise Chip Control: The HS geometry is optimized to break chips at light-to-medium depths, preventing long stringy chips that can damage surface finishes.
- Low Cutting Resistance: Sharp edge design reduces the load on the machine spindle and tool holder, ideal for small-to-medium lathes.
- Universal Application: Simplify your inventory by using one grade (PC5300) for various materials.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 100 - 220 m/min | 0.08 - 0.25 mm/rev | 0.5 - 3.0 mm |
| Stainless Steel (304/316) | 80 - 160 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.5 mm |
| Cast Iron (GG25) | 120 - 250 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.5 mm |
Compatible Tool Holders:
Precision fit for all ISO standard negative holders:

Machinist Tip: Why choose PC5300?
Understanding the versatility of the PC5300 grade:
The Safety Pick. Use PC5300 when you don't know the exact material hardness or when the machine is vibrating. Its PVD coating is much tougher than CVD (like NC3020), preventing edge fracture in difficult setups.
High-Speed Stainless. If you are ONLY cutting stainless steel in high-volume production, PC9030 might offer slightly better life. But for general repair or job shop work, PC5300 is the superior all-rounder.
Pro Advice: The -HS chipbreaker on the SNMG120404 is quite sharp. To prevent early wear, avoid using it for heavy roughing on forged "black" skins. For skin removal, switch to the -HM or -HR chipbreakers.
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.
