XPMT 040104 AH740 – Indexable insert for drilling by Tungaloy

The XPMT 040104 AH740 indexable insert is designed for general drilling within the TungDrillTwisted TDX system and for straightforward integration into TDX/C‑TDX drill bodies.

• PVD-coated carbide grade AH740 for wear resistance
• Compatible with TDX indexable drilling systems
• Cylindrical hole with single-sided countersink
• Corner radius 0.4 mm and 11° clearance angle

Consistent performance through coating and grade selection

The combination of a PVD-coated surface and cemented carbide substrate in the AH740 grade provides a balance between wear resistance and a sharp cutting edge. This translates into longer tool life and process security in batch and continuous drilling operations. The coating reduces adhesion and heat build-up at the cutting edge, while the substrate maintains toughness to resist chipping under varying cutting conditions. As part of the TungDrillTwisted family, the insert is intended for use in TDX drill bodies, enabling repeatable performance across similar setups.

Practical advantages for stable drilling and chip control

The insert’s geometry supports reliable chip formation: the chipbreaker DW is optimised for clearing swarf in common drilling tasks, and the cylindrical hole with single-sided countersink assists secure clamping and alignment on the seat. The small corner radius 0.4 mm combined with an 11° clearance angle provides a clean entry and reduced cutting forces, which benefits hole quality and tool life. With a plate thickness of 1.59 mm and the special plate form, the insert offers mechanical stability for a wide range of diameters and L/D ratios; selection of diameter, L/D, shank and the appropriate insert should be matched to machine capability, workpiece material and cooling strategy for optimum results.

System approach and application benefits for production

Using the insert together with TDX/C‑TDX drill bodies, clamping screws and the recommended keys delivers a modular drilling system that simplifies inventory and increases machine uptime. The insert is particularly suitable for general drilling operations where a combination of process reliability and resistance to chipping is required. Operators gain predictable hole quality and reduced rework, while production planners benefit from the straightforward replacement routine and the availability of matching components in the TungDrillTwisted range.

FAQ

Is this insert suitable for general-purpose drilling in steel?
The XPMT040104R-DW AH740 indexable insert (Tungaloy, SKU 6821615-Tungaloy) is designed for general drilling and is appropriate for a range of steel applications when paired with the correct TDX drill body and machining parameters.

How does the AH740 grade affect tool life and process security?
The AH740 grade combines a wear-resistant PVD coating with a tough substrate to reduce chipping and extend edge life, improving process security in repetitive drilling cycles.

What is the role of the chipbreaker DW on this insert?
The chipbreaker DW is tuned to produce controllable chips and efficient evacuation during drilling, which reduces the risk of re-cutting and helps maintain hole integrity.

Can this insert be used with any TDX body length or does it depend on L/D ratio?
The insert is part of the TungDrillTwisted family and can be used across TDX body variants; selection of body length and L/D ratio should match the intended drilling depth, machine rigidity and coolant conditions.

Which features support secure clamping and accurate seating of the insert?
The insert’s cylindrical hole with a single-sided countersink ensures reliable clamping and alignment on the seat, contributing to consistent hole quality and repeatable positioning.
