XPMT 08T308 AH9030 indexable insert for full-bore drilling – PVD-coated carbide by Tungaloy

XPMT 08T308 AH9030 is an indexable insert designed for TDX full-bore drilling systems, optimised for a sharp cutting edge and high process reliability in general drilling applications

• PVD-coated carbide AH9030 for edge strength
• 0.8 mm corner radius for consistent finishes
• Cylindrical hole with single countersink 40°–60°
• Chipbreaker DJ for controlled swarf evacuation

Consistent edge life through wear-resistant grade

The AH9030 grade is a PVD-coated carbide developed to provide wear- and chipping-resistant performance where a sharp cutting edge is essential. Its coating and substrate combination reduce flank wear and maintain a stable cutting edge, which leads to repeatable hole tolerances and extended intervals between indexings. For operations prioritising cycle stability, this translates into predictable tool-change schedules and fewer unscheduled stoppages.

Secure clamping and chip control reduce rework

A precise cylindrical hole with a single countersink (40°–60°) and the tailored chipbreaker DJ combine to ensure reliable seating and effective swarf control during drilling. The controlled geometry stabilises the insert under axial and radial loads, while the chipbreaker shapes the cut material to reduce interference with coolant flow. Together these features help to lower the risk of built-up edge and minimise surface defects, improving first-pass quality.

Geometry tuned for reliable surface quality

The insert’s 0.8 mm corner radius and 3.97 mm plate thickness support consistent surface finishes and dimensional control across a range of feeds and speeds. The special plate form provides a defined cutting edge contour, enabling operators to select a compromise between robustness and edge sharpness depending on the workpiece requirement. This makes the insert suitable where process security and a defined finish are required rather than aggressive material removal alone.

System approach for faster serviceability and compatibility

As part of the TungDrillTwisted family, the insert is intended for use with TDX/C-TDX drill bodies and a complete accessory set including clamp screws and keys. The modular system design simplifies inventory management: matching inserts, bodies and fastenings are chosen according to overhang (L/D) and interface to suit the machine and coolant strategy. This system mindset reduces changeover time on the shopfloor and supports efficient integration into existing drilling processes.

FAQ

Which materials is this insert suitable for?
The XPMT08T308R-DJ AH9030 insert is designed for applications where a sharp cutting edge and process security are required; its PVD-coated carbide construction provides general versatility across common machining tasks.

How does the chipbreaker DJ affect machining?
The chipbreaker DJ on the XPMT08T308R-DJ shapes chips to improve evacuation and coolant interaction, reducing the likelihood of chip jamming and promoting stable cutting conditions.

Can the insert be used with existing TDX drill bodies?
Yes, the insert is intended for the TungDrillTwisted family and is compatible with TDX/C-TDX drill bodies; matching the insert ISO and seat is essential for proper clamping and performance.

What is the benefit of the cylindrical hole with single countersink?
The cylindrical hole with a single countersink (40°–60°) ensures a secure mechanical location and optimised clamp force distribution, which supports repeatable seating and improved process reliability.

How should replacement inserts be stocked for efficient shop use?
Store matched sets of inserts, clamp screws and keys to reduce changeover time; using the modular system approach of the TungDrillTwisted family simplifies selection and inventory control.
