Tungaloy XPMT150512R-DJ AH725 Indexable Drill Insert – Optimized for Steel & Stainless Performance
High-precision drilling solution featuring the ultra-tough AH725 PVD grade. Designed for superior chip breaking and reliable tool life in demanding CNC drilling operations.
Product Overview
"Which drilling insert provides the most stable performance and chip control when drilling deep holes in alloy steel or stainless steel?"
The Tungaloy XPMT150512R-DJ AH725 is a premium indexable insert engineered for the high-productivity TAC Drill series. The DJ (Drilling Joint) chipbreaker is specialized for drilling, utilizing a unique rake geometry that breaks chips into short, manageable curls to prevent clogging and surface marring. Combined with the AH725 PVD grade—a high-AlTiN coating on a high-toughness carbide substrate—this insert offers exceptional resistance to both thermal cracking and edge chipping, making it the "first choice" for a wide range of materials (P and M groups).

Why Choose Us
Machinist Reviews
"Perfect fit for our TDX340 drill. Chip control on alloy steel is night and day compared to generic inserts."
"AH725 hat eine sehr gute Standzeit bei der Bearbeitung von Edelstahl. Sehr prozesssicher."
"Ottimo rompitruciolo DJ. Le punte indexabili Tungaloy sono una garanzia."
Frequently Asked Questions
💡 Machinist's Tip: AH725 Versatility
While AH725 is a "universal" drilling grade, if you are strictly machining Cast Iron (K), consider shifting to AH120 for better wear resistance. For high-temp alloys, ensure fn is maintained at the lower end of the recommended range to protect the coating.
Technical FAQ & Buying Guide
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.
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.
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.
