Tungaloy WNMG080408-TM T9115 Turning Insert

High-Speed Steel Machining | Premium CVD Coated T9115 Grade

"Which turning insert is most reliable for high-productivity medium cutting in carbon and alloy steels?"

The Tungaloy WNMG080408-TM T9115 is a high-performance, double-sided 80° trigon turning insert engineered for the P15-P25 range of Steel and Cast Iron. The TM chipbreaker (Technical Medium) features a balanced geometry designed to minimize cutting forces while maintaining excellent chip evacuation across a wide range of feed rates. Powered by T9115 CVD technology, this insert utilizes a specialized thick alumina layer that provides ultimate heat resistance, allowing for significantly higher cutting speeds without compromising tool life. With a 0.8mm corner radius, it offers the perfect combination of edge strength and surface finish quality for general-purpose industrial machining.

T9115 Premium CVD Coating

The "PremiumTec" coating surface treatment reduces friction and inhibits built-up edge (BUE), ensuring stable tool life in high-speed continuous turning.

TM Chipbreaker Geometry

Optimized for medium-duty machining. The large rake angle and chip pocket design prevent chip congestion and bird-nesting in ductile steels.

6 Cutting Edges

The 80° Trigon (W-shape) design provides 6 usable cutting edges per insert, offering 50% more value compared to standard 4-edged CNMG inserts.

Global Industry Feedback

⭐⭐⭐⭐⭐ "Workhorse Grade" - Mark T., USA
"We run WNMG080408-TM in 4140 steel all day. The T9115 grade is a beast. Consistent 200+ parts per edge at high speeds."

⭐⭐⭐⭐⭐ "Reliable Chip Control" - Hans L., Germany
"The TM chipbreaker is very consistent. Even with low feeds, the chips break properly. Great value with 6 edges."

⭐⭐⭐⭐ "Fast Shipping, Quality Product" - Matteo L., Italy
"Authentic Tungaloy. Noticed a 20% increase in tool life over my previous brand in gray iron turning."

Technical FAQ

Q: Can I use T9115 for Stainless Steel?

A: T9115 is a dedicated steel grade. While it can cut stainless, for optimal tool life and chip control, we recommend Tungaloy's AH series (PVD) or specific stainless CVD grades.

Q: What depth of cut is ideal for the TM breaker?

A: For the WNMG080408 size, the TM breaker performs best at a Depth of Cut (ap) between 1.0mm and 4.5mm.

Pro Machining Tip: Speed is Key

The **T9115** coating works best when it's hot. If you're experiencing built-up edge (BUE) or edge chipping at low speeds, try **increasing your cutting speed (Vc)**. The CVD layer thrived on heat. **BEYOND CNC** - Powering Your Precision.

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.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
