How does the T9125 grade handle various steel alloys?
The T9125 grade is Tungaloy's "all-rounder" for steel turning. It features a specialized multi-layer CVD coating that provides excellent heat barrier protection and prevents crater wear. This long-tail keywords industry favorite is designed with an optimized substrate that offers higher resistance to chipping compared to harder grades like T9115. For precision machining in carbon and alloy steels, T9125 ensures a highly predictable and long tool life.
What makes the PS chipbreaker effective for finishing?
The PS Chipbreaker geometry is a ground-profile design optimized for finishing to light semi-finishing operations. Its sharp cutting edge reduces power consumption and minimizes vibration, which is crucial for achieving high surface quality on the workpiece. This indexable turning tool excels in breaking chips at light feed rates, preventing stringy chips from scratching the finished surface during CNC machining.
What are the recommended feeds and speeds for this insert?
Optimized for P (Steel) Applications:
-
Cutting Speed (Vc): 120 - 320 m/min (390 - 1050 SFM)
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Note: For stainless steel applications, consider Tungaloy's T6120 grade for optimized performance.*
Global Customer Feedback
⭐⭐⭐⭐⭐ "Predictable and Tough" - Matthias K., Germany

Technical Q&A
Q: What tool holder should I use with this insert?
A: This insert is designed for any standard **SCLCR09** or **SCLCR3/8** external turning holder or boring bar.
Q: Is T9125 suitable for heavy roughing?
A: While T9125 is tough, the PS chipbreaker is optimized for finishing and semi-finishing. For heavy roughing, a more robust chipbreaker like PM or HM would be better suited.
Q: Does this insert require coolant?
A: While T9125 CVD coating handles heat well, coolant is recommended to enhance chip evacuation and maintain surface finish quality.
Expert Machining Tip: CVD vs. PVD for Steel
For high-speed steel turning where heat generation is a concern, CVD Coated Carbide (T9125) is the superior choice. Its thicker coating and superior thermal barrier protect the carbide substrate, ensuring consistent tool life in CNC machining environments.
