XPMT 08T308 AH7020 indexable insert for drilling — Tungaloy

The XPMT08T308R-DW AH7020 is an indexable insert developed for full-bore insert drilling in the TungDrillTwisted family, optimised for process security and sharp cutting edges

• PVD-coated AH7020 carbide grade
• Designed for TDX/C‑TDX drilling bodies
• 0.8 mm corner radius for controlled cutting
• Cylindrical hole with one-sided countersink

Reliable drilling through wear-resistant grade and coating

The insert is built on a PVD-coated AH7020 carbide substrate that combines resistance to wear and chipping with a consistently sharp cutting edge. This composition delivers a rational advantage in production: longer tool life and fewer interruptions for index changes or regrinds. As part of the TungDrillTwisted system the insert contributes directly to improved process stability and predictable component quality during general drilling tasks.

Geometry designed for controlled chips and accurate seating

The insert geometry is engineered for reliable chip control and secure clamping. The 0.8 mm corner radius and DW chipbreaker promote regular chip formation and protect the cutting edge under varying feed rates, while the 11° free angle supports stable cutting forces. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for accurate positioning and positive mechanical engagement in TDX bodies. Plate thickness 3.97 mm and size 08 ensure robust support and repeatable seating.

Compatibility within a modular drilling system for flexibility

This family is differentiated by overhang (L/D) and interface and is supplied as a modular kit of TDX/C‑TDX drill bodies, XPMT inserts, clamping screws and key. That modularity allows selection of diameter, L/D ratio, shank and insert grade to match machine capability, workpiece material and coolant strategy. The result is an efficient workflow: fewer tool variants, faster set-ups and the ability to adapt to diverse drilling requirements without sacrificing performance.

Practical advantages for production environments

In production the combination of a modern PVD coating and a purpose‑designed chipbreaker reduces downtime and enhances first‑pass quality, translating into measurable productivity gains. The insert’s special plate form and secure hole geometry provide consistent clamping behaviour, while the wear‑resistant grade helps maintain surface finish and dimensional accuracy over longer runs. For operations seeking dependable indexable solutions, this insert supports both process reliability and practical maintenance routines.
