Description

Tungaloy VCMT160408-PS T9125 Turning Insert

General Purpose Steel Machining | Premium CVD Grade | -PS Sharp Finishing Geometry

Which insert is most reliable for general steel turning and interrupted finishing?

The Tungaloy VCMT160408-PS T9125 is a high-versatility 35° rhombic insert engineered for workshops that demand stability across a wide range of steel machining tasks. The T9125 grade combines a tough carbide substrate with a specialized CVD coating, making it the primary choice for P20-P35 steel applications involving both continuous and light interrupted cuts. Featuring the -PS (Positive Sharp) chipbreaker, it reduces cutting resistance and ensures excellent chip evacuation at shallow depths of cut, providing a high-gloss finish on alloy and carbon steels with a stronger 0.8mm corner radius for increased edge stability.

Finishing

T9125 Tough CVD Grade

Designed for high-stability machining in P25 steel. Resists thermal cracking and fracture during slightly interrupted cuts, extending tool life in non-ideal setups.

-PS Sharp Edge

The positive geometry reduces tool pressure, minimizing work hardening and workpiece vibration. Perfect for achieving high Ra surface quality.

0.8mm Radius Strength

The 160408 designation provides a robust corner radius that allows for higher feed rates while maintaining structural integrity against chipping.

Global Customer Reviews

⭐⭐⭐⭐⭐ "Workhorse Grade" - Mark R., USA
"T9125 is my daily driver for steel. The 0.8mm radius on the VCMT160408 is tough enough for the occasional bump without losing the edge."

⭐⭐⭐⭐⭐ "Mirror Finish" - Dieter S., Germany
"The -PS geometry provides a clean, glossy surface even on alloy steels. Very reliable for our shaft production."

⭐⭐⭐⭐ "Great Stability" - Luca V., Italy
"Consistent tool life across every box. We push these at 250m/min and the CVD coating holds up beautifully."

⭐⭐⭐⭐⭐ "Reliable B2B Supplier" - T. Nakamura, Japan
"Authentic Tungaloy parts. Fast shipping to Tokyo. The technical support here is exceptional."

Technical FAQ

Q: Can I use T9125 for stainless steel?

A: While primarily a steel grade (P25), it can perform in some ferritic stainless applications. For dedicated stainless work, we recommend the AH600/AH700 series.

Q: What is the optimal ap for the -PS breaker?

A: The -PS is a finishing breaker. It performs best at depths of cut between 0.3mm and 1.5mm.

Q: Is this insert suitable for dry machining?

A: The T9125 CVD coating is heat-resistant, but coolant is highly recommended for finishing to ensure superior surface quality and chip evacuation.

Machinist Tip: Edge Preparation

When using the **T9125** grade on harder alloys, ensure your spindle speed (Vc) is high enough to activate the CVD coating's self-lubricating properties. This reduces built-up edge (BUE) and significantly improves finish Ra. **BEYOND CNC** - Reliability in Every Edge.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.
