XPMT 050204 AH725 XPMT – Drilling solution by Tungaloy

The XPMT050204R-DJ AH725 XPMT is an indexable‑insert full‑hole drilling system designed for general drilling, featuring TDX drill bodies and the universal, breakout‑resistant AH725 insert grade.

• TDX drill body with exchangeable XPMT inserts
• AH725 PVD-coated carbide for steel and stainless steel
• Cylindrical hole with single-sided countersink

Consistent production through a flexible insert system

The TungDrillTwisted family delivers a modular approach to conventional drilling: TDX and C‑TDX drill bodies accept the exchangeable inserts specified for diameter, L/D ratio and machine interface, enabling rapid adaptation to varying jobs. Using the XPMT insert geometry together with a TDX holder reduces tool change time and simplifies inventory management compared with solid drills. The AH725 grade, a PVD‑coated carbide, has been developed for universal use and reliable chip formation, which supports stable cutting conditions when processing both unalloyed steel and stainless steel. For production planners this means predictable performance across mixed lots and fewer emergency stoppages due to insert failure.

Reliable hole quality and improved chip control

Designed with a DJ chipbreaker and a corner radius of 0.4 mm, this insert form maintains consistent chip evacuation and prevents edge chipping in medium‑to‑high cutting forces. The insert’s cylindrical fastening hole with a single‑sided countersink (40°–60°) secures positioning and repeatability, translating into improved surface finish and dimensional consistency. The 11° clearance angle and 2.38 mm plate thickness contribute to stable cutting engagement and resistance to vibration, which in turn reduces rework and scrap rates. For users unfamiliar with this terminology: the chipbreaker shapes the chips so they break into short segments, keeping flutes clear and helping coolant access the cutting zone.

Lower running costs through fast maintenance and process security

Replacing an insert is markedly quicker than regrinding or fitting new solid drills, and the TDX system uses standard clamping screws and keys for straightforward servicing. The carbide composition and PVD coating together extend useful life, especially in smaller diameters and in applications where frequent material changes demand robust performance. The family’s classification by overhang (L/D) and interface facilitates selection for deep or short borings while maintaining process security. For operations seeking to raise throughput without extensive capital outlay, this system offers a pragmatic balance of productivity and predictable tool life.

FAQ

What materials are recommended for this insert and grade?
The XPMT050204R-DJ AH725 insert is specified for steel and stainless steel and is suitable where mixed‑material batches require a universal, breakout‑resistant performance.

How does the AH725 grade improve process security?
AH725 is a PVD‑coated carbide grade designed for stable chip formation and reduced edge breakout; when combined with the XPMT geometry it delivers repeatable cutting behaviour and predictable tool life.

Can the insert handle deep hole drilling with longer overhangs?
The TungDrillTwisted family is differentiated by overhang (L/D) and interface; selecting the appropriate TDX body and L/D variant ensures the XPMT insert performs reliably in deeper bores.

What role does the DJ chipbreaker play in machining?
The DJ chipbreaker forces chips to fracture into short segments, improving evacuation and reducing flute clogging, which enhances surface quality and reduces machining interruptions.

Is the insert easy to replace during shift work?
Yes; the system uses clamping screws and a simple key for fast insert changes, minimising downtime compared with regrinding or replacing solid tools.
