XPMT150512 AH740 indexable insert — PVD‑coated carbide, 1.2 mm corner radius (Tungaloy)

XPMT150512 AH740 is an indexable insert designed for general drilling in the TungDrillTwisted family, suited for applications where a sharp cutting edge and process reliability are required

• PVD-coated grade AH740 for wear resistance
• Designed for TungDrillTwisted indexable drills
• Cylindrical hole with single-sided countersink
• 1.2 mm corner radius, 11° clearance angle

Delivering consistent chip control and drilling reliability

The PVD‑coated carbide composition of the insert provides elevated resistance to flank wear and micro‑chipping, ensuring longer intervals between tool changes and a stable machining process. The plate’s integrated chipbreaker geometry and one‑sided design promote predictable chip formation during full‑bore operations, which reduces vibration and supports constant material evacuation. In practice, this translates into fewer scrap parts and more reproducible hole quality during medium‑ to high‑volume drilling tasks.

Longer edge life and process security for demanding operations

A precisely specified corner radius of 1.2 mm combined with an 11° clearance angle balances edge strength and cutting efficiency. The rounded corner reduces the risk of edge fracture under interrupted cuts, while the clearance protects the flank from rubbing and thermal degradation. The AH740 grade’s PVD finish further improves abrasion resistance and maintains a sharp cutting line, delivering predictable tool life and a stable surface finish that supports downstream processes.

Seamless system integration for quick tool setup

This indexable insert is manufactured for the TungDrillTwisted family and mates with TDX drill bodies that accept XPMT plates; the system is completed with clamping screws and a key for secure fastening. The plate’s cylindrical hole and single‑side countersink (40°–60°) ensure repeatable seating and simple indexing during maintenance. Selection of diameter, L/D, shank and suitable insert variant should be matched to the machine, coolant strategy and cycle requirements to achieve the intended productivity gains.

Practical advantages in everyday drilling workflows

Designed as a special‑form insert with a nominal plate size of 15, the component simplifies inventory management by combining robustness with straightforward identification. The AH740 cutting grade is optimised for resistance to wear and chipping, making the insert appropriate where edge integrity and process reliability are priorities. Handling and replacement follow standard indexable‑insert procedures, enabling fast changeovers and minimal spindle downtime.

FAQ

What is the primary application for this insert?
The XPMT150512 AH740 insert is intended for full‑bore drilling within the TungDrillTwisted system and is optimised where a sharp cutting edge and process security are required.

Which drill bodies accept this insert?
The indexable insert is designed to be used with TDX and C‑TDX drill bodies that accept XPMT plates; proper seating is ensured by the cylindrical hole and single‑side countersink.

What does the AH740 designation mean for performance?
AH740 denotes a PVD‑coated carbide grade that offers improved wear resistance and reduced susceptibility to chipping, contributing to longer tool life and stable drilling performance with the XPMT insert.

How do the corner radius and clearance angle affect machining?
A 1.2 mm corner radius increases edge robustness for interrupted cuts, while an 11° clearance angle limits flank contact and helps maintain cutting efficiency and surface quality.

What should be considered when selecting the correct insert version?
Selection should consider bore diameter, L/D ratio, shank interface and the machine’s coolant arrangement; these factors ensure the chosen XPMT insert performs reliably within the TungDrillTwisted system.
