XPMT 08T308 AH7030 indexable insert for drilling — PVD-coated carbide, 0.8° corner radius — Tungaloy

The XPMT 08T308 AH7030 indexable insert is a specialised cutting plate for general drilling within the TungDrillTwisted system, designed to deliver process security and a sharp, wear-resistant cutting edge.

PVD-coated carbide AH7030 for wear resistance
DW chipbreaker for improved chip control
0.8 mm corner radius for edge strength
Cylindrical hole with single-sided countersink 40°–60°

High-performance wear resistance for uninterrupted drilling

The insert uses a PVD-coated carbide grade (AH7030) formulated for wear and notch resistance, which extends tool life under continuous drilling conditions. This material combination maintains a sharp cutting edge, reducing the need for frequent index changes and supporting longer uninterrupted production runs. The design suits general drilling where a balance between edge life and cutting precision is required, helping to keep cycle times consistent and rework minimal.

Predictable chip formation and process stability

Equipped with the DW chipbreaker, the plate promotes controlled chip formation and evacuation, which is essential when integrating the insert into the modular TungDrillTwisted drill body. Stable chip control reduces the risk of built-up edge and improves surface finish, particularly on mixed batches and varied materials. By pairing the insert with the correct drill body, shaft and machine parameters, reliable process behaviour is achieved, increasing overall productivity.

Design features that support secure clamping and alignment

The plate includes a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping and repeatable seating in the TDX/ C‑TDX drill bodies. The 0.8 mm corner radius and the insert’s special form contribute to robust edge geometry, lowering the likelihood of chipping during entry and exit. These mechanical design details facilitate quick insert changes and predictable positioning, which is vital for reproducible hole quality and reduced setup time.

Flexible system use and application guidance

As a member of the TungDrillTwisted model family, the insert integrates into a replaceable-insert full-drill system that is differentiated by overhang length, L/D ratio and interface. Selection of the correct diameter, L/D, shank and the XPMT insert should be matched to the machining centre, workpiece material and coolant strategy. The system construction comprises TDX/C‑TDX drill bodies, XPMT inserts, clamping screws and the required key, enabling a modular approach to tool inventory and fast adaptation to diverse drilling tasks.
