Tungaloy WNMG060412E-TM T9125 Turning Insert
Superior Toughness for High-Speed Steel Turning & Medium Cutting
Product Overview
"Which insert provides the best edge strength for medium turning of alloy steel while maintaining a long tool life at high speeds?"
The Tungaloy WNMG060412E-TM T9125 is the industry benchmark for general steel turning (ISO P). Utilizing the T9125 CVD grade, it features PremiumTec surface technology which significantly reduces friction and crater wear. The TM (Medium-cut) chipbreaker is paired with a robust 1.2mm nose radius, making it the ideal choice for applications requiring high edge security, increased feed rates, and excellent chip evacuation in carbon and alloy steels.
Core Performance Advantages
- T9125 CVD Grade: Multi-layered coating (TiCN-Al2O3) optimizes wear resistance and thermal protection at high speeds.
- Robust 1.2mm Radius: Provides exceptional edge strength, allowing for higher feed rates and improved durability in rougher environments.
- TM Geometry: Optimized chipbreaker land provides a stable cutting edge that prevents crater wear during medium turning.
- Six Cutting Edges: The Trigon (W) shape offers the economy of multiple edges with the strength of a square insert.

Why Machinists Trust T9125
"The 1.2mm radius is a beast for our rougher alloy steel parts. T9125 holds the edge twice as long as our previous brand."
— Mike D., USA"Ottima resistenza. Rompitruciolo TM perfetto per acciai da costruzione."
— Alessandro M., Italy"Consistent performance in high-speed production. My first choice for 1045 steel."
— Hiroshi S., Japan"Top Standzeit bei Stahl. Sehr zuverlässig bei mittleren Schnitttiefen."
— Klaus K., GermanyFrequently Asked Questions
Q: Is the 1.2mm radius too large for finishing?
A: This radius is optimized for medium-to-heavy cutting. While it can finish, it requires a higher feed rate to avoid vibration and may not be suitable for very fine precision finishes compared to a 0.4mm radius.
Q: What is 'E' in the model code?
A: The 'E' refers to the cutting edge treatment (honing/rounding). This increases edge security and prevents premature chipping under load.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
