XPMT 040104 AH725 indexable insert for drilling — PVD‑coated carbide, r0.4 — Tungaloy

A XPMT040104R‑DW AH725 indexable insert designed for TDX full‑drill systems, intended for general drilling in steel and stainless steels and optimised for high process security

• PVD‑coated carbide AH725 for mixed materials
• Suitable for TDX full‑drill bodies
• 0.4 mm corner radius for precise hole entry
• Cylindrical hole with single‑side countersink (40°–60°)

Consistent performance and process security for drilling

The XPMT insert is built on a PVD‑coated carbide substrate in grade AH725, a universal, breakout‑resistant formulation suited to steel and stainless steels. This composition combines wear resistance with controlled chip formation, which helps to maintain a stable cutting edge and reduces the frequency of unexpected edge failures. For operations that switch between materials or require dependable cycle times, this insert supports reproducible results and lower scrap rates.

Precision geometry reduces rework and improves hole quality

With a 0.4 mm corner radius and an 11° free angle, the insert geometry eases entry and distributes cutting forces to lower vibration and deflection. The special plate form and the DW chipbreaker manage chips effectively, while the cylindrical hole with single‑side countersink (40°–60°) ensures secure clamping on the TDX carrier. Together, these features lead to a cleaner hole profile, reduced need for secondary finishing, and consistent diameters across batches.

Modular system benefits: fast changeovers and predictable tooling costs

The insert is part of the TungDrillTwisted family of interchangeable components: TDX drill bodies, XPMT inserts, clamping screws and keys. The modular concept enables quick insert changes without removing the drill body, reducing machine downtime and simplifying tool inventory. For workshops seeking to balance flexibility with repeatability, the system offers an efficient route to standardised set‑ups and straightforward reconditioning of cutting edges.

Materials and machining recommendations

The grade and geometry are selected for general drilling; use the insert in conjunction with TDX bodies matched to the required overhang and L/D ratio. The 1.59 mm plate thickness and size 04 suit compact, high‑security applications where insert seating and coolant delivery are critical. Where possible, verify cutting data against machine rigidity and coolant type to exploit the AH725 grade’s ability to handle variable materials without compromising tool life.

FAQ

What materials is the XPMT040104R‑DW AH725 suited for?
The Tungaloy XPMT040104R‑DW AH725 insert is formulated for steel and stainless steels, offering stable chip control and process security when machining mixed batches.

How does the chipbreaker DW influence drilling performance?
The DW chipbreaker on the XPMT insert promotes short, controllable chips that reduce evacuation issues and help maintain a consistent cutting edge during prolonged drilling cycles.

Can the insert be used in any TDX drill body?
Yes, the insert is intended for the TungDrillTwisted TDX family; ensure the chosen TDX body matches the required overhang and L/D ratio for the application.

What does the ISO code 040104 indicate?
The ISO code 040104 defines the insert’s geometry and size class; it corresponds to the 04 plate size and the specific corner radius and relief angles used in this insert design.

Is the AH725 grade suitable for varying workpiece materials?
The AH725 PVD‑coated grade is a universal, breakout‑resistant carbide designed to handle a range of steels and stainless steels, making it appropriate where material types vary or process reliability is critical.
