TNMG160404 UC5105
Mitsubishi Materials | The High-Speed Cast Iron Specialist
The Mitsubishi TNMG160404 UC5105 is an elite CVD coated carbide insert engineered for high-velocity turning of cast iron. Utilizing the UC5105 ultra-hard grade, this tool is designed to resist the extreme abrasion and heat generated during high-speed cast iron turning. As a primary long-tail precision tool for industrial manufacturing, it ensures maximum tool life and dimensional stability when machining Gray Cast Iron (FC) and high-strength Ductile Iron (FCD).

UC5105 CVD Grade
The UC5105 grade is Mitsubishi's premium solution for indexable turning inserts used in cast iron. It features an ultra-thick alumina ($Al_2O_3$) coating that provides industry-leading flank wear resistance. This grade is optimized for stable turning at the highest possible surface speeds, reducing cycle times significantly.
TNMG Multi-Edge Design
The TNMG geometry offers 6 usable cutting edges, providing a superior cost-per-edge for CNC machining. The 0.4mm nose radius is ideal for finishing to semi-finishing passes, where low cutting forces and high precision are required for thin-walled or high-tolerance cast iron parts.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Gray Cast Iron (FC300) | 250 - 600 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.0 mm |
| Ductile Cast Iron (FCD) | 180 - 400 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |
