XPMT 050204 AH7020 indexable drilling insert for TDX drill bodies — Tungaloy

The XPMT050204R-DJ AH7020 is an indexable full-bore insert designed for TDX drill bodies, engineered to deliver stable, wear-resistant performance in general drilling applications.

• PVD-coated carbide AH7020 for wear resistance
• Precise 0.4 mm corner radius for repeatable holes
• DJ chipbreaker for stable chip control
• Cylindrical hole with one-sided countersink for secure clamping

High process security through wear-resistant grade

The insert employs a PVD-coated cutting material of grade AH7020, a wear- and fracture-resistant cemented carbide developed for drilling. This combination reduces flank wear and maintains a sharp cutting edge over longer intervals, which leads to fewer tool changes and more predictable cycle times. The result is improved process security and a higher effective productivity when used in demanding production runs.

Consistent hole quality and secure clamping

A defined 0.4 mm corner radius and a relief angle of 11° support consistent hole geometry and controlled cutting forces, reducing the risk of burr formation and dimensional scatter. The insert features a cylindrical hole with a one-sided countersink, designed to guarantee positive seating and repeatable clamping in compatible drill bodies; this ensures mechanical stability during high-feed passes and when machining varied workpiece materials.

Efficient chip control and machining stability

The DJ chipbreaker is tuned for reliable chip segmentation and evacuation during through-cut drilling, lowering the chance of chip jamming and improving surface quality. Integrated into the indexable full-bore system of the TungDrillTwisted family, the insert is intended for use with TDX drill bodies and benefits from a system approach — matching insert geometry, body overhang and coolant strategy to achieve stable cutting conditions with minimal setup effort.

Practical integration and application support

Insert dimensions such as 2.38 mm plate thickness and size 05 make the component easy to specify in existing tool lists; selection should consider diameter, L/D ratio, shank interface and coolant arrangement to match machine and workpiece. Application advice and cutting data are available to support implementation and process optimisation. Application advice is available from Metav Werkzeuge to assist with tool selection and parameter tuning.

FAQ

What materials is this insert suitable for?
The XPMT050204R-DJ AH7020 insert is specified for general drilling tasks; grade AH7020 is wear- and fracture-resistant and provides a wide material coverage when matched with appropriate cutting data.

How does the DJ chipbreaker affect machining performance?
The DJ chipbreaker enhances chip segmentation and evacuation, promoting stable cutting forces and reduced risk of chip-related interruptions when using the indexable full-bore system.

How is the insert clamped in the drill body?
Clamping is achieved via the insert’s cylindrical hole with a one-sided countersink, which ensures secure seating and repeatable positioning in compatible TDX drill bodies.

Which dimensions should be checked before ordering?
Check corner radius (0.4 mm), plate thickness (2.38 mm), size (05) and relief angle (11°); reference the manufacturer article number 6952948 or SKU TUN6952948 when ordering.
