Mitsubishi CNMG120408-GH UC5115

“Struggling with tool breakage in interrupted cuts? Switch to UC5115 and machine cast iron with total confidence.”

• Geometry: CNMG 120408 — 80° rhombic negative insert, 4-edged, IC = 12.7 mm, thickness = 4.76 mm.
  
  Corner Radius: 0.8 mm (coded “08”). 

• Chip Breaker: GH — built to handle unstable / interrupted cuts, high edge strength, plus a large chip pocket. 

• Grade & Coating: UC5115 — a tough substrate coated with a nano-texture CVD coating: fibrous TiCN + thick, even Al₂O₃ (all-black super-even coat) for high wear resistance and chipping resistance.
  
  Cutting Applications: Primarily turning, especially effective in cast iron and ductile cast iron. 

• Exceptional Durability: The advanced coating gives dramatically increased wear life, while the tough substrate resists fracture — leading to fewer insert changes and less unplanned downtime.
  
  Stable Performance in Challenging Conditions: Thanks to the GH chip breaker, this insert excels in unstable or interrupted cuts, delivering consistent chip control and preventing edge chipping. 

• Cost-Efficient Machining: Longer tool life + fewer insert rotations = lower cost per component — saving money in high-volume production.

• Automotive: Turning cast-iron engine blocks, brake components, differential carriers.

• Aerospace / Defense: Components made from ductile iron or similar.

• Die & Mold: Rough and semi-finish turning of hardened or cast tooling components.

• General Engineering: Heavy-duty cast-iron work, pump housings, heavy machinery parts.
