Korloy RPMT10T3MO-Q PC5300 10mm Universal Round Milling Insert for Steel & Stainless (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy RPMT10T3MO-Q PC5300 is a high-versatility 10.0mm Round (RPMT) Milling Insert, precision-engineered as the "workhorse" for general-purpose machining. Featuring the advanced PC5300 PVD coating, this insert excels in cutting Steel, Stainless Steel, and Cast Iron. The -Q (Light Cutting) chipbreaker provides a sharp yet strong edge, making it the ideal choice for 3D profiling, ramping, and face milling where stability and predictable tool life are paramount.
Superior PVD Versatility: PC5300 is Korloy’s flagship universal grade. Its high-toughness substrate combined with a multi-layered TiAlN coating allows it to handle interrupted cuts and varying material hardness with ease, reducing the need for frequent insert changes between different jobs.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | RPMT10T3MO-Q |
| Insert Shape | Round (RP) |
| Diameter / Thickness | 10.0 mm / 3.97 mm |

Core Performance Benefits:
- Wide Material Coverage: One insert for multiple materials—effectively mill Carbon Steel, Alloy Steel, Stainless Steel (304/316), and Ductile Iron.
- Excellent Edge Strength: The PC5300 substrate is designed to resist chipping even in heavy-interrupted or "dirty" surface milling.
- Sharp Shearing Action: The -Q geometry reduces spindle load and vibrations, improving surface finish on large 3D profiled cavities.
- Economical Design: The round shape allows for multiple indexing positions (simply rotate the insert), maximizing cost-per-edge.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed per Tooth (fz) |

Machinist Tip: Why PC5300 is the Universal Leader
Choosing between PC5300 and other specialized Korloy grades:
The Tough All-Rounder. Best choice if you process a mix of materials (Steel today, Stainless tomorrow). It provides the highest security against unexpected breakage in unstable setups.
The Stainless Specialist. If you exclusively machine 316L Stainless or sticky superalloys, PC9030 might offer longer life due to its higher lubrication, but PC5300 remains the more versatile choice.
Pro Advice: For RPMT10T3MO-Q PC5300, utilize the chip thinning advantage of round inserts. By increasing the feed per tooth (fz) while maintaining a shallow depth of cut, you can achieve massive metal removal rates without overheating the insert.
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.
