The Original Korloy MGMN150-T PC5300 is a high-precision 1.5mm Double-Ended Grooving Insert engineered for micro-machining and narrow parting applications. Utilizing the renowned PC5300 universal PVD grade, this insert is the gold standard for workshops that demand extreme reliability in small-scale operations. The 1.5mm width minimizes material waste (kerf loss), making it perfect for high-value materials and precision components in the medical, electronics, and automotive industries.
Precision with Toughness: The -T chipbreaker is specially designed to control chips in extremely narrow grooves. Combined with the tough PC5300 substrate, it resists the micro-chipping often associated with high-precision, low-feed rate applications.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN150-T |
| Insert Width (w) | 1.5 mm (+/- 0.02) |
| Grade | PC5300 (Universal High-Toughness PVD) |
| Application | Steel (P), Stainless (M), Cast Iron (K) |
Core Performance Benefits:
- Minimal Material Waste: The 1.5mm ultra-narrow edge saves significant material cost on high-volume production runs.
- Superior Edge Strength: PC5300 provides the toughness needed to survive the "center-cut" shock during parting-off operations.
- Optimized Chip Evacuation: The -T geometry forces thin chips to curl tightly, preventing "bird-nesting" in deep, narrow grooves.
- Broad Versatility: One insert grade for multiple materials, simplifying your tool inventory.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon/Alloy Steel | 90 - 160 m/min | 0.03 - 0.08 mm/rev |
| Stainless Steel | 70 - 120 m/min | 0.02 - 0.06 mm/rev |
| Pre-hardened Steel | 40 - 80 m/min | 0.02 - 0.05 mm/rev |

- External Holders: MGEHR 1010-1.5 / 1212-1.5 / 1616-1.5
Precision Selection: PC5300 vs. PC9030
When working with 1.5mm widths, the smallest vibration can cause failure. Choosing the right grade is vital:
The Toughness Expert. Essential for 1.5mm widths where edge fragility is a concern. Use this if your setup isn't perfectly rigid or if you're cutting various steel alloys.
The Stainless Specialist. Optimized for the chemical properties of stainless steel. Better for mass production of stainless parts, but less forgiving of vibration than PC5300.
Machinist's Pro Tip: For MGMN150-T PC5300, ensure your centerline height is perfectly aligned. Even a 0.1mm deviation can cause a 1.5mm insert to snap during parting-off because the tool pressure becomes uneven.
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.
