XPMT 040104 AH7020 indexable insert for drilling – Tungaloy

The XPMT 040104 AH7020 is an indexable insert designed for general drilling, offering a wear- and chipping-resistant cutting grade for stable, reproducible performance in modular drill systems.

• PVD-coated AH7020 grade for wear resistance
• DW chipbreaker for controlled chip formation
• 0.4 mm corner radius for accurate hole finish
• Cylindrical hole with 40°–60° countersink

Longer tool life through a wear-resistant cutting grade

The insert XPMT040104R-DW AH7020 is built on a carbide substrate with a PVD-coated top layer (AH7020) developed for drilling applications where a sharp cutting edge and reliable performance are required. The PVD coating reduces flank wear and improves surface integrity, which translates into longer intervals between index changes and lower overall tooling costs. As a result, process stability is increased, and tool-change downtime is reduced, contributing to a smoother production flow and measurable productivity gains.

Predictable chip formation for safer, faster cycles

The combination of the DW chipbreaker and the specialised geometry produces consistent chip shapes and evacuation, which reduces the risk of chip snarling and improves cycle reliability. Controlled chip control is particularly important for medium to deep-hole operations and varied material mixes. By stabilising the cutting process, the insert supports higher feed rates and steadier cutting conditions, which commonly leads to improved throughput without sacrificing hole quality.

A modular system that adapts to machine and application

Designed for use in TDX drill bodies within the TungDrillTwisted family, this insert forms part of a modular drilling solution where diameter, L/D ratio, shank type and insert selection can be matched to the machine, workpiece material and coolant strategy. The system layout—TDX/C-TDX bodies, XPMT inserts, clamping screws and assembly key—allows straightforward retrofitting and simplification of inventory by standardising on proven interfaces and insert formats, enabling consistent set-up across different machines.

Precision geometry for consistent hole quality

Technical details such as the 0.4 mm corner radius, an 11° relief angle and a plate thickness of 1.59 mm support accurate hole profiles and a reliable edge form at the cutting zone. The insert features a cylindrical hole with a one-sided countersink (40°–60°) to secure seating and axial location in the drill body; this design ensures repeatable positioning and stable cutting engagement. These geometric choices help to lower vibration sensitivity and improve surface finish, delivering holes that meet tight dimensional and cosmetic tolerances.

FAQ

What applications is this insert designed for?
The XPMT040104R-DW AH7020 insert is designed for general drilling operations where a sharp cutting edge and reliable process behaviour are required; it forms part of a modular drilling system for flexible application.

How does the DW chipbreaker improve drilling?
The DW chipbreaker on this insert promotes controlled chip formation and evacuation, which enhances process stability and reduces the likelihood of chip-related interruptions during drilling.

Can these inserts be used in TDX drill bodies?
Yes, the insert is intended for use with TDX/C-TDX drill bodies within the TungDrillTwisted system, enabling standardised mounting and secure clamping.

Why is the 0.4 mm corner radius important?
A 0.4 mm corner radius strikes a balance between edge strength and hole finish: it increases cutting-edge robustness while maintaining the ability to produce accurate hole diameters and good surface quality.

How are the inserts secured in the drill body?
The system uses clamping screws and an assembly key as part of the TDX set-up; the insert's cylindrical hole with a one-sided countersink ensures correct seating and repeatable positioning.
