MITSUBISHI XDGT1550PDFR-G32 TF15
Heavy-Duty Aluminum Roughing | Massive 3.2mm Radius | Made in Japan
Product Overview
The Mitsubishi XDGT1550PDFR-G32 TF15 is a specialized milling insert engineered for high-efficiency Aluminum (N-Class) and non-ferrous alloy machining. Unlike standard variants, the G32 geometry features a large 3.2mm corner radius, providing exceptional edge strength for heavy roughing and high-speed pocketing. Utilizing TF15 micro-grain carbide, this insert is non-coated and mirror-polished to prevent chip welding (BUE). For CNC machining professionals who need to move massive amounts of material quickly while maintaining a superior surface finish, these indexable carbide inserts are the industry benchmark.

Grade: TF15 Uncoated Micro-Grain
The TF15 grade is Mitsubishi’s premier solution for non-ferrous materials. By using a specialized micro-grain substrate without a coating, the insert maintains a razor-sharp edge. This is critical for aluminum precision machining, as it reduces cutting forces and heat. The polished rake face acts as a lubricant-free surface that effectively eliminates chip sticking, even during long-tail keywords heavy material removal cycles.
The G32 Roughing Power
The G32 chipbreaker is specifically designed for high-stress milling. The 3.2mm radius offers a significantly more robust edge than standard R0.4 or R0.8 inserts, allowing for higher depths of cut and aggressive feed rates. It is the ideal geometry for CNC milling of large aluminum components like engine blocks or aerospace frames.
Recommended Cutting Parameters
Optimized for Aluminum (N-Class):
-
Cutting Speed (Vc): 300 - 1200 m/min (980 - 3940 SFM)
-
Feed per Tooth (fz): 0.15 - 0.40 mm/t (0.006 - 0.016 ipt)
-
Depth of Cut (ap): Up to 14.0 mm
*Note: Due to the large R3.2 radius, ensure your CAM software is programmed for proper corner clearance.*
Global Customer Feedback
⭐⭐⭐⭐⭐ "Extreme Metal Removal" - James H., USA
"We rough out huge 7075 blocks with these. The 3.2mm radius is incredibly tough. No chipping even at high feeds."
⭐⭐⭐⭐⭐ "Mirror Surface" - Yuki K., Japan
"The TF15 grade is perfect. We get a mirror finish on our aluminum housings every time. Authentic quality."
⭐⭐⭐⭐ "Great for Pocketing" - Oliver L., UK
"Very stable in high-speed pocketing. The polished face prevents any chip welding. Highly recommended."
⭐⭐⭐⭐⭐ "Reliable Tool Life" - Chen L., Singapore
"Consistent performance across all 10 inserts in the box. Mitsubishi quality is second to none for aluminum work."
⭐⭐⭐⭐⭐ "Genuine Product" - Sandro M., Italy
"Original packaging, original performance. The G32 radius really helps with tool life in heavy cuts."
Technical Q&A
Q: Can I use TF15 for Stainless Steel?
A: No. TF15 is an uncoated grade for Aluminum. For Stainless Steel, we recommend the VP15TF grade with PVD coating.
Q: What are the benefits of the 3.2mm radius?
A: It provides superior edge strength for rough turning and milling, allowing for higher feed rates and deeper cuts without risking tip failure.
Q: Do these fit the standard AXD cutters?
A: Yes, they are fully compatible with Mitsubishi AXD4000 milling bodies.
Expert Machining Tip: TF15 vs. HTi10
While HTi10 is a classic choice, TF15 offers better toughness and edge retention for modern high-speed CNC machining. For extreme high-silicon alloys, consider a DLC coating for even greater longevity.
