Tungaloy CNMG160608 T9115 Turning Insert
High-Speed Steel Specialist | CVD Coated Durability | Japan Precision Tooling
What makes T9115 the best grade for high-speed steel turning?
The Tungaloy CNMG160608 T9115 is a robust CVD coated carbide turning insert engineered for high-efficiency machining of carbon and alloy steels. The T9115 grade utilizes Tungaloy's "PremiumTec" surface technology, featuring a thick Al2O3 layer that provides exceptional heat resistance and prevents crater wear during high-velocity cuts. This indexable turning tool is designed for the heavy-duty demands of CNC machining, offering superior edge toughness and stability. With a 0.8mm corner radius, it delivers the perfect balance of edge strength and surface finish quality. Made in Japan, this insert is a benchmark for precision machining where maximizing tool life and minimizing downtime are critical for industrial productivity.

Can I use T9115 for heavy roughing on alloy steel?
The T9115 CVD Grade is specifically optimized for high-speed continuous cutting. Its multi-layer coating structure provides the necessary toughness to withstand the high temperatures of steel turning without sacrificing edge sharpness. This long-tail keywords industry favorite is widely implemented in CNC machining centers for large-scale production. Because the CNMG160608 is a larger, thicker insert (6.35mm thickness), it possesses the mass and thermal stability required for heavier cuts compared to the standard CNMG12 size. This ensures a more reliable and productive precision machining experience with extended tool life.
Recommended Cutting Parameters for T9115
Optimized for P (Steel) and K (Cast Iron):
-
Cutting Speed (Vc): 150 - 450 m/min (Material dependent)
-
Feed Rate (f): 0.15 - 0.50 mm/rev
-
Depth of Cut (ap): 1.0 - 6.0 mm
*Note: CVD coatings thrive at higher speeds. For best results, ensure your CNC lathe can maintain consistent spindle speed.*
Verified Reviews from Global Shops
⭐⭐⭐⭐⭐ "Extreme tool life at high speed" - Markus B., Germany
"Switched to T9115 for our 4140 steel production. We increased the cutting speed and still got 30% more parts per edge than our previous brand."
⭐⭐⭐⭐⭐ "Stable and Strong" - Kenji S., Japan
"The CNMG16 size is perfect for our heavy duty shafts. The T9115 coating holds up very well against heat. Authentic Tungaloy quality."
⭐⭐⭐⭐ "Great for mass production" - David L., USA
"Very predictable wear patterns. Makes it easy to schedule tool changes in our automated CNC cell."
⭐⭐⭐⭐⭐ "Handles the heat" - Luca V., Italy
"Running these at 300m/min and they just keep cutting. Best CVD grade for steel turning on the market."
⭐⭐⭐⭐⭐ "Original & Reliable" - Liam G., Australia
"100% genuine Japan stock. Fast delivery and top performance. The thick 1606 thickness makes a huge difference in stability."
Technical Machinist Q&A
Q: Is T9115 suitable for stainless steel?
A: T9115 is optimized for Steel (P). For stainless steel (M), we recommend PVD grades like AH725 to prevent built-up edge and notch wear.
Q: What tool holder fits the CNMG1606 size?
A: These inserts fit any standard **DCLNR16** or **MCLNR16** turning holder. Note that these are larger than the common 1204 size.
Q: Does this work for interrupted cuts?
A: For heavy interruptions, T9125 might be a tougher choice. T9115 is best for continuous, high-speed turning.
Expert Insight: CVD vs. PVD for Steel
For high-speed CNC machining of steel, CVD Coated Carbide (T9115) is superior to PVD. The thicker coating provides a massive thermal barrier, allowing for the high surface speeds necessary to achieve elite tool life and productivity levels.
