MITSUBISHI XDGX227008PDFR-GL TF15
High-Speed Aluminum Expert | Mirror-Polished Rake Face | Made in Japan
Product Overview
The Mitsubishi XDGX227008PDFR-GL TF15 is a high-precision milling insert specifically engineered for the high-velocity demands of Aluminum (N-Class) and non-ferrous alloy machining. Utilizing the world-class TF15 micro-grain carbide grade, this insert features a razor-sharp cutting edge and a mirror-polished rake face. These features are critical in CNC machining to prevent "chip welding" and built-up edge (BUE). Designed for the AXD series, these indexable carbide inserts provide exceptional thermal stability and surface finish quality, making them a top-tier choice for aerospace and automotive aluminum milling.

Material: TF15 (Non-Coated Perfection)
The TF15 grade is a specialized uncoated carbide insert substrate. By utilizing a micro-grain structure, Mitsubishi has achieved a perfect balance of hardness and toughness. In aluminum milling, coatings can sometimes round the cutting edge; the uncoated TF15 maintains a razor-sharp profile which is essential for long-tail keywords reduction of cutting resistance and ensuring a high-definition surface finish.
GL Chipbreaker Optimization
The GL geometry is designed for light-to-medium milling applications. It focuses on low cutting force and superior chip control. This geometry, combined with the 0.8mm radius, provides excellent versatility for precision machining across various aluminum alloys, including high-silicon casting alloys.
Recommended Cutting Parameters
Optimized for Aluminum & Non-Ferrous (N-Class):
-
Cutting Speed (Vc): 400 - 1800 m/min (1310 - 5900 SFM)
-
Feed per Tooth (fz): 0.10 - 0.35 mm/t (0.004 - 0.014 ipt)
-
Depth of Cut (ap): Up to 15.0 mm
*Note: Use high-pressure coolant to facilitate rapid chip evacuation and prevent heat build-up.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Aerospace Grade Finish" - Thomas B., Canada
"We use these for thin-wall aluminum parts. The low cutting force of the GL geometry is a game changer. Mirror finish every time."
⭐⭐⭐⭐⭐ "Incredibly Sharp" - Hiroshi S., Japan
"Authentic TF15 grade. The edge sharpness is superior to anything else we've tried for 6061-T6. Highly recommended."
⭐⭐⭐⭐ "Stable at High RPM" - Gunter M., Germany
"Ran these at 1500 m/min. The chip evacuation is smooth and the insert looks new after hours of cutting."
⭐⭐⭐⭐⭐ "Reliable Tool Life" - Liam W., Australia
"Consistent quality across the whole pack. Original Mitsubishi packaging and performance."
⭐⭐⭐⭐⭐ "Best for CNC Aluminum" - Sacha L., France
"Very fast metal removal rates. The polished face really does stop the aluminum from sticking to the tip."
Technical Q&A
Q: Why is the rake face polished?
A: A mirror-polished face reduces friction, allowing chips to slide off easily. This prevents aluminum from welding to the insert, which is the main cause of tool failure.
Q: Is this insert suitable for finishing?
A: Yes, the R0.8 precision radius and sharp TF15 edge make it an excellent choice for both semi-finishing and high-quality finishing.
Q: Which cutter body should I use?
A: These inserts are designed for the Mitsubishi AXD4000/AXD7000 series milling bodies.
Expert Machining Tip: TF15 vs. DLC Coating
For standard aluminum jobs, TF15 is highly efficient. For extreme high-silicon alloys (>12% Si) that are very abrasive, consider moving to a DLC (Diamond-Like Carbon) coated insert to extend edge life.
