The Original Korloy MGMN500-T PC5300 is a heavy-duty 5.0mm Double-Ended Grooving Insert engineered for maximum stability in aggressive machining. Designed for those who prioritize edge security above all else, the -T (Tough) geometry features a reinforced cutting edge that excels in interrupted cuts, scaly surfaces, and high-tensile alloys. Paired with the PC5300 universal PVD grade, this 5.0mm insert provides unmatched reliability for heavy-duty parting and deep radial grooving.
Superior Impact Resistance: At 5.0mm width, the cutting forces are immense. The MGMN500-T is specifically designed to absorb mechanical shocks from cross-holes, splines, or irregular workpiece shapes, preventing the catastrophic fractures that often plague standard sharp inserts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN500-T |
| Insert Width (w) | 5.0 mm (+/- 0.04) |
| Grade | PC5300 (Universal High-Toughness PVD) |

Core Performance Benefits:
- Maximum Edge Security: The reinforced -T land is designed to withstand heavy vibration and interrupted cutting cycles.
- Extreme Toughness Grade: PC5300 substrate is optimized for reliability across Steel (P), Stainless (M), and Cast Iron (K).
- 5.0mm Massive Profile: Provides the rigidity needed for deep radial plunging in large-diameter industrial shafts.
- Heat Resistance: Advanced PVD coating maintains edge hardness even during the high thermal loads of wide grooving.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon/Alloy Steel (Standard) | 80 - 160 m/min | 0.15 - 0.30 mm/rev |
| Interrupted Alloy Steel | 50 - 100 m/min | 0.12 - 0.25 mm/rev |
| Ductile Iron (GGG40/50) | 70 - 130 m/min | 0.18 - 0.35 mm/rev |
Compatible Tool Holders:
Due to the high torque of 5.0mm grooving, we recommend heavy-duty MGEHR/L holders:
- External Holders: MGEHR 2525-5 / 3232-5 / 4040-5
Pro Choice: Why -T Geometry at 5.0mm?
When machining large 5.0mm wide grooves, the choice of geometry can save your workpiece:
The Unstoppable Force. Optimized for shock resistance. Best for large shafts with keyways, rough casting surfaces, or any situation where the tool takes a heavy beating.
The Efficiency Specialist. Sharper than the -T, providing better chip control and lower power consumption in continuous cuts of clean steel.
Machinist's Pro Tip: For MGMN500-T PC5300, when performing heavy parting of solid bars, ensure your coolant pressure is high. The wide 5.0mm chip creates significant friction; constant lubrication is key to maximizing the life of this tough-grade insert.
Packaging: 10 pieces per box.
