Tungaloy SNMM190624-TU T9225 Heavy Turning Insert
Maximum Metal Removal | Premium T9225 CVD Grade | Heavy-Duty TU Chipbreaker
What is the most durable carbide insert for heavy roughing of steel?
The Tungaloy SNMM190624-TU T9225 is a powerhouse designed for extreme metal removal rates in ISO P (Steel) and ISO K (Cast Iron). This insert features the latest T9225 CVD coating technology, which offers unprecedented wear resistance and edge toughness. The heavy-duty -TU chipbreaker is engineered with a reinforced cutting edge to handle massive depths of cut and high feed rates, even in interrupted or unstable conditions. 100% Made in Japan, it is the ultimate tool for heavy engineering and large-scale industrial machining.
T9225 Advanced Coating
The T9225 grade features a thick, highly textured Al2O3 layer that provides exceptional heat resistance and prevents flank wear during high-speed, long-duration roughing.
-TU Reinforced Breaker
The "TU" geometry is built for heavy roughing. It utilizes a wide chip pocket and a robust edge land to ensure stable chip evacuation at high feed rates without edge chipping.
Large 2.4mm Radius
The 2.4mm corner radius provides maximum edge strength. This allows the insert to withstand the massive cutting forces generated during heavy-duty external turning.

Global Heavy Industry Feedback
⭐⭐⭐⭐⭐ "Extreme Metal Removal" - Robert T., Australia
"The SNMM190624 is a monster. We're taking 8mm deep cuts on large forged cylinders and it doesn't even flinch. The T9225 grade lasts much longer than our previous inserts."
⭐⭐⭐⭐⭐ "Unbeatable for Roughing" - F. Schneider, Germany
"The TU chipbreaker is very robust. Even with heavily interrupted cuts, we don't see any chipping. Japanese quality at its best."
⭐⭐⭐⭐ "Great Stability" - K. Kobayashi, Japan
"Very predictable tool life. This is critical for our 24/7 production runs on heavy machinery parts. Highly recommended for heavy lathes."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - M. Rahim, Singapore
"Always genuine Tungaloy stock from CNCHome-Beyond. Fast shipping and the technical support provided helps us optimize our cycles."
⭐⭐⭐⭐⭐ "Heavy Duty Performance" - G. Brown, Canada
"We use these for mining equipment repairs. The 2.4mm radius is incredibly strong. Excellent value for the price."
8. FAQ - Heavy Turning Support
Q: Can I use this for finishing?
A: No. The SNMM-TU is a heavy roughing insert. For finishing, use a smaller radius (04 or 08) and a -TS or -TM chipbreaker.
Q: Is T9225 better than T9125 for heavy cuts?
A: Yes. T9225 is the newer generation grade with improved heat resistance and toughness specifically for ISO P steel roughing.
Q: What is the benefit of the 2.4mm radius?
A: It provides a much stronger cutting edge that can handle higher feeds and more aggressive depths of cut without fracturing.
Expert Tip: Heavy Metal Removal Strategy
The **SNMM190624-TU** is built for maximum productivity. To get the best results, prioritize depth of cut (ap) over cutting speed (Vc) to reduce heat at the tip while maintaining high metal removal. Trust **Tungaloy Japan** for the most reliable heavy roughing in the industry.
