Korloy FGD500R-04 PC215K 5mm Single-Ended Grooving Insert for Cast Iron (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy FGD500R-04 PC215K is a specialized Single-Ended Parting and Grooving Insert designed specifically for the heavy-duty machining of Cast Iron (K). The 5.0mm cutting width provides extreme structural integrity for deep-plunge grooving in large industrial components. Utilizing the PC215K PVD grade, this insert features a high-hardness substrate and a heat-resistant coating that excels in the abrasive environment of Grey Cast Iron (GG) and Ductile Iron (GGG). Its single-ended design ensures the maximum clamping surface, effectively eliminating vibration and ensuring flat, precise groove bottoms.
The Cast Iron Powerhouse: Machining cast iron often leads to abrasive wear and micro-chipping. The PC215K grade is engineered to resist these specific wear patterns, providing much longer tool life and better dimensional stability in mass production than multi-material grades.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | FGD500R-04 |
| Insert Design | Single-Ended (Heavy Load) |
| Width (w) | 5.0 mm |

Core Performance Benefits:
- Maximum Rigid Seating: The single-ended long-body design is critical for the high cutting forces generated by 5mm wide cuts in tough ductile iron.
- Abrasive Wear Resistance: PC215K coating is designed to handle the silica and graphite inclusions found in cast irons without dulling prematurely.
- Exceptional Edge Strength: The R0.4 radius and FGD geometry prevent edge chipping during interrupted cuts on rough castings.
- Optimized Chip Control: FGD chipbreaker specifically manages the short, brittle chips of cast iron to keep the work area clean.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Grey Cast Iron (GG25) | 120 - 220 m/min | 0.12 - 0.28 mm/rev |
| Ductile Iron (GGG40/50) | 100 - 180 m/min | 0.10 - 0.22 mm/rev |
| High Strength Cast Iron | 80 - 150 m/min | 0.08 - 0.18 mm/rev |
Compatible Tool Holders:
For 5mm wide heavy cutting, use high-rigidity 25mm or 32mm holders:
- External Grooving Holders: FGDR 2525-5 / FGDR 3232-5
Cast Iron Expert Tip: PC215K vs. PC9030
Choosing the right grade for your 5.0mm groove makes the difference between consistent production and frequent tool changes:
The Specialist. Higher hardness than PC9030. It is much more resistant to the abrasive particles in cast iron. Use this for GG/GGG to achieve maximum tool life.
The All-Rounder. Best for Stainless Steel. While it can cut iron, it will wear out much faster due to lower surface hardness compared to the PC215K.
Machinist's Pro Tip: Cast iron often has a hard, abrasive outer "skin." When starting the groove with an FGD500R, ensure the first pass is deep enough to get the tool tip below the casting crust immediately to protect the cutting edge.
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.
