Korloy MGMN500-M H01 | 5.0mm Mirror-Finish Insert for Aluminum
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN500-M H01 is a high-precision 5.0mm Double-Ended Grooving Insert specifically designed for Aluminum, Copper, and Non-Ferrous Metals. Featuring the specialized H01 Uncoated Grade with a mirror-polished top surface, this insert eliminates the common problem of "chip welding" or built-up edge (BUE). The 5.0mm width offers exceptional rigidity for deep grooving and heavy-duty parting in large aluminum components, providing a surface finish that often eliminates the need for secondary polishing.
Mirror-Finish Performance: The H01 grade is diamond-lapped to achieve a razor-sharp edge and ultra-smooth rake face. This ensures that aluminum chips slide away effortlessly, even at high cutting speeds, maintaining high dimensional accuracy for 5.0mm grooves.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN500-M |
| Insert Width (w) | 5.0 mm (+/- 0.04) |
| Grade | H01 (Uncoated Mirror-Polished Carbide) |
| Chipbreaker | -M (Universal Sharp Geometry) |
Core Performance Benefits:
- Anti-Stick Surface: Mirror-polished rake face prevents aluminum chips from welding to the tool.
- Razor Sharp Edge: Uncoated carbide allows for a much sharper edge than coated grades, crucial for clean cuts in soft metals.
- 5.0mm Rigid Body: Optimized for heavy parting and deep plunging in large aluminum shafts and pulley wheels.
- Exceptional Tool Life: High-purity micro-grain carbide resists abrasive wear from silicon-rich aluminum alloys.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Aluminum Alloys (Wrought) | 200 - 800 m/min | 0.10 - 0.35 mm/rev |
| Cast Aluminum (Si < 12%) | 150 - 500 m/min | 0.12 - 0.30 mm/rev |
| Copper & Brass Alloys | 150 - 400 m/min | 0.08 - 0.25 mm/rev |
Compatible Tool Holders:
To handle the high speeds of aluminum machining with 5.0mm inserts, use these rigid holders:
- External Holders: MGEHR 2525-5 / 3232-5
The Non-Ferrous Choice: H01 vs. PC9030
Why use an uncoated insert for aluminum instead of a coated one?
The Aluminum King. No coating means the edge remains razor-sharp. The mirror-polish prevents the chemical reaction that makes aluminum stick to the tool.
The Steel Specialists. PVD/CVD coatings have microscopic roughness that aluminum can grab onto, leading to built-up edge and poor surface finish in non-ferrous metals.
Machinist's Pro Tip: For MGMN500-M H01, "Speed is your friend." Aluminum can be machined at very high $Vc$ rates. Using high-pressure coolant or a mist system will help flush the wide 5.0mm chips away and keep the part cool to maintain tight tolerances.
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.
