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).

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.
