Material: LC15TF (Titanium & Alloy Expert)
The LC15TF grade is specifically developed for difficult-to-cut materials. Unlike universal grades, it utilizes a specialized PVD coating with a high thermal stability threshold. In precision machining of titanium, heat often concentrates at the cutting edge; LC15TF dissipates this heat effectively to prevent thermal cracking. The 1.2mm radius (G12) is the long-tail keywords sweet spot for roughing to semi-finishing, providing the toughness needed for interrupted cuts in tough skins.
Robust G12 Chipbreaker
The G12 geometry provides a slightly reinforced edge compared to G04, making it highly reliable for CNC milling of tough alloys. It maintains a positive rake angle to ensure smooth chip flow and reduced spindle load, even when machining materials with high work-hardening tendencies.
Recommended Cutting Parameters
Optimized for Titanium & Super Alloys (S-Class):
-
Cutting Speed (Vc): 40 - 90 m/min (130 - 300 SFM)
-
Feed per Tooth (fz): 0.10 - 0.25 mm/t (0.004 - 0.010 ipt)
-
Depth of Cut (ap): Up to 10.0 mm
*Note: High-pressure through-coolant is highly recommended for Titanium to ensure long tool life.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Best for Ti-6Al-4V" - Alexander K., Germany
"We struggled with insert life on titanium aerospace parts. Switched to LC15TF and our cycle count per edge doubled. Outstanding."
⭐⭐⭐⭐⭐ "Incredible Edge Toughness" - Robert M., USA
"The 1.2mm radius is perfect for roughing. No chipping even when hitting hard spots in the casting. Highly recommended."
⭐⭐⭐⭐ "Very Stable Performance" - Kenzo T., Japan
"Consistent wear pattern makes it easy to predict tool changes. Essential for our lights-out manufacturing."
⭐⭐⭐⭐⭐ "Genuine Mitsubishi Quality" - David P., UK
"Authentic inserts. Packaged well and performance is top-tier. LC15TF is my go-to for Inconel roughing."
⭐⭐⭐⭐⭐ "Fast Shipping, Great Product" - Sven H., Sweden
"Received original boxes in perfect condition. The G12 radius provides a very strong edge for tough materials."
Technical Q&A
Q: Can I use LC15TF for Aluminum?
A: While it can cut aluminum, it is not ideal. For Aluminum, the TF15 grade (uncoated) is far superior for preventing chip welding.
Q: Why use a 1.2mm corner radius?
A: The R1.2 (G12) radius offers significantly more edge strength than R0.4 or R0.8, which is critical when machining high-strength alloys like Titanium.
Q: Does this fit standard AXD cutters?
A: Yes, these are designed to fit the Mitsubishi AXD4000 milling body series.
Expert Machining Tip: LC15TF vs. VP15TF
For general purpose steel and stainless, VP15TF is the standard. However, for Titanium and Inconel, the LC15TF grade is essential as it is optimized for high-temperature stability.
