Advanced Grade: UE6110 (High-Speed Specialist)
The UE6110 grade is Mitsubishi's ultimate solution for high-speed Steel (P-Class) turning. It utilizes a thick CVD coating with optimized crystal orientation, which provides industry-leading resistance to cratering at high temperatures. This means you can push your CNC lathe to higher surface speeds without compromising tool life, making it perfect for high-volume production of carbon and alloy steel parts.
SA Medium-Cut Chipbreaker
The SA chipbreaker is the versatile choice for medium cutting. Its geometry is designed to handle a wide variety of depths of cut while maintaining smooth chip evacuation. In CNC turning, the SA breaker minimizes cutting resistance, which reduces heat buildup—a critical factor when paired with the high-speed capabilities of the UE6110 grade.
⭐⭐⭐⭐⭐ "Blazing Speed" - Robert H., USA "We pushed our surface speed to 320 m/min on 1045 steel and these UE6110 inserts didn't even flinch. Cycle times are way down."
⭐⭐⭐⭐⭐ "Stable and Reliable" - Dieter S., Germany "Excellent Japanese quality. The SA chipbreaker handles our varied depths of cut with perfect consistency."
⭐⭐⭐⭐ "Great for Mass Production" - Akira M., Japan "Very predictable wear patterns. This is essential for our automated shifts where we can't afford unexpected tool failures."
⭐⭐⭐⭐⭐ "Cost-Effective 6 Edges" - Liam F., Australia "The trigon shape gives us 6 edges which is a huge cost advantage over CNMG. Paired with UE6110 durability, it's a winner."
⭐⭐⭐⭐⭐ "Fast Delivery & Original" - Mateusz Z., Poland "Genuine Mitsubishi inserts. The high-speed performance is exactly as listed in the catalog. Highly recommended."
Technical Q&A
Q: Is UE6110 good for interrupted cuts?
A: UE6110 is optimized for High-Speed Continuous cutting. For heavy interrupted cuts, the UE6020 or MC6025 grade may provide better impact resistance.
Q: What is the benefit of the SA chipbreaker?
A: It is a general-purpose medium-cut breaker that balances edge strength with sharp cutting. It works across a wide range of feed rates in Steel.
Q: How many edges do I get per insert?
A: WNMG is a double-sided trigon, giving you 6 usable cutting edges, making it 50% more efficient than standard 4-edge diamond inserts.
Expert Machining Tip: UE6110 vs. UE6020
For Maximum Productivity at high speeds, UE6110 is the king. If your setup has Stability Issues or you are doing varied work with interruptions, UE6020 is the more forgiving choice.
