Korloy SDXT130508R-MM PC6510 Milling Insert for Cast Iron (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SDXT130508R-MM PC6510 is a high-performance Square Milling Insert, precision-engineered for the most demanding Cast Iron (K-Group) and Hardened Steel applications. Featuring the specialized PC6510 PVD Grade, this insert provides an ultra-hard TiAlN coating that excels in high-heat environments and resists the abrasive wear typical of grey and ductile iron. The -MM (Medium-Medium) chipbreaker is versatile, providing a perfect balance between edge strength and smooth cutting action for face milling and shoulder milling.
Cast Iron Specialist: The PC6510 grade is a game-changer for machining cast iron. It prevents the rapid flank wear often seen in standard inserts, allowing for significantly higher cutting speeds (Vc) and much longer tool life in GG25 and GGG40 materials.

Machinist Tip: PC6510 vs PC5300 in Milling
Choosing the right milling grade for your job:
Cast Iron Master. PC6510 is significantly harder than PC5300. It is designed specifically to resist the abrasive nature of cast iron. Use this for high-speed face milling to get the longest life.
Universal Toughness. PC5300 is better for general steel or if your setup is unstable. However, in cast iron, PC5300 will wear down much faster than the specialized PC6510.
Pro Advice: When milling cast iron with SDXT130508R-MM PC6510, dry cutting (no coolant) is often recommended to prevent thermal shock, which can lead to micro-cracking of 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.
