XPMT 110412 AH725 (XPMT110412R-DS) – Indexable insert for drilling, TungDrillTwisted by Tungaloy

A robust XPMT110412R-DS indexable insert developed for full-bore, modular drilling systems; ideal for general drilling tasks where process stability and insert interchangeability are required

• PVD-coated carbide grade AH725 for process security
• Designed for TungDrillTwisted TDX modular bodies
• Special form insert with cylindrical hole and countersink
• Universal, breakout-resistant for steel and stainless steels

Reliable process security for mixed-material production

The PVD-coated AH725 cemented carbide delivers a balance of wear resistance and toughness that supports stable chip formation across a wide range of steels and stainless steels. In combination with the insert’s DS chipbreaker geometry, the cutting edge reduces the risk of insert breakouts and ensures repeatable hole quality even when workpiece materials vary. The TDX modular concept permits selection of the appropriate body, shaft and L/D ratio so that the system can be tailored to machine capability and coolant strategy, supporting higher productivity and lower scrap rates.

Faster tool setup and adaptable drilling configurations

Modularity is at the heart of the TungDrillTwisted family: the system uses TDX/C‑TDX drill bodies with XPMT indexable inserts, clamping screws and a single key for straightforward assembly. This modular approach shortens changeover times and simplifies inventory management. The insert’s cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and correct seating in the drill body, while the defined corner radius and relief angle support consistent cutting conditions across varying diameters and L/D demands.

Improved tool life and consistent surface finish

The combination of a PVD-coated surface and a breakout‑resistant grade reduces flank wear and chipping under interrupted cuts or inconsistent material batches, extending the usable lifetime of each indexable element. As a result, the drilling process becomes more predictable and achieves better surface finishes with fewer rework operations. For smaller tools and applications where process reliability is critical, the AH725 grade offers a cost‑effective compromise between edge stability and wear resistance.

Clear selection criteria and practical application tips

When choosing an insert and drill body combination, match insert size, corner radius (R = 1.2 mm) and relief angle (11°) to the desired hole size and machine rigidity. For applications requiring reliable chip evacuation and stable cutting, select the DS chipbreaker form and ensure the TDX body variant suits the intended L/D ratio. The special insert form and the presence of a cylindrical hole with countersink facilitate accurate indexation and secure fastening in the drill body, minimising vibration and promoting process consistency.

FAQ

What materials is this insert suited for?
The XPMT110412R-DS insert in AH725 is designed primarily for steels and stainless steels, offering universal, breakout‑resistant performance across mixed batches.

How does the AH725 coating improve drilling performance?
The PVD‑coated AH725 grade increases surface hardness and wear resistance while retaining edge toughness, which supports stable chip formation and longer insert life in drilling operations.

Which drill bodies are compatible with this insert?
The insert is intended for use with TungDrillTwisted TDX and C‑TDX drill bodies as part of a modular full‑bore system; secure clamping is achieved via the cylindrical hole and countersink arrangement.

What does the DS chipbreaker provide?
The DS chipbreaker is configured to promote controlled chip breakage and evacuation, reducing the likelihood of chip entanglement and improving hole quality.

How should the insert be selected for a specific L/D ratio?
Select the appropriate TungDrillTwisted body variant to match the required L/D; then choose the XPMT insert size and corner radius that correspond to the hole diameter and machine rigidity.
