XPMT 08T308 AH725 XPMT08T308R-DW — Insert for Drilling (Tungaloy)

The XPMT08T308R-DW AH725 is an exchangeable-insert solution from the TungDrillTwisted series, designed for general drilling applications with TDX drill bodies and optimised for steel and stainless steels.

• Exchangeable insert full-bore system
• PVD-coated AH725 universal grade
• Suitable for steel and stainless steels
• 0.8 mm corner radius for precise holes

Productivity through an exchangeable-insert system

The TungDrillTwisted family combines TDX drill bodies with the XPMT insert concept to reduce tooling costs and downtime. The system’s modular design enables fast insert changes and predictable tool-life cycles, which translates into shorter machine idle times and more efficient batch production. By separating the cutting edge from the body, reconditioning and inventory management become simpler while maintaining consistent results across repetitive runs.

Reliable cutting performance with AH725 grade

The PVD-coated AH725 grade is a universal, fracture-resistant carbide developed for mixed-material production where process security is critical. The coating improves wear resistance under varying cutting conditions and supports stable chip formation when machining both carbon steels and stainless steels, making the insert a sensible choice for shops facing frequent material changes. This yields fewer rejected parts and a steadier production rhythm.

Hole accuracy and chip control for demanding components

A corner radius of 0.8 mm and a relief angle of 11° contribute to dimensional stability and edge strength during drilling. The plate’s special form and the DW chipbreaker are engineered to promote controlled chip flow, reducing the risk of clogging in medium-depth holes. The insert design, combined with the specified thickness of 3.97 mm, helps maintain concentricity and improves surface finish in through-holes and blind-hole operations.

System composition and application guidance for optimal use

The family is differentiated by overhang/L‑D ratios and interfaces; typical assemblies comprise TDX/C‑TDX drill bodies, XPMT inserts, clamping screws and the required keys. Selection should be made according to required diameter, L/D ratio, shank type and the chosen XPMT insert variant, taking into account machine rigidity and cooling strategy. Matching these parameters ensures the system delivers the expected balance of productivity and tool life.

FAQ

What materials is this insert suitable for? The XPMT08T308R-DW AH725 is specified for machining steel and stainless steels; the AH725 PVD-coated carbide provides broad applicability and improved process security across these materials.

How does the corner radius affect hole quality? A 0.8 mm corner radius increases edge strength and contributes to dimensional stability, producing more consistent hole diameters and improved surface finish during drilling operations.

What does the DW chipbreaker do? The DW chipbreaker is designed to promote controlled chip formation and evacuation, which reduces the risk of clogging and supports stable cutting conditions in medium-depth drilling.

Which drill bodies are compatible with these inserts? The inserts are intended for use with TDX and C‑TDX drill bodies as part of the TungDrillTwisted system; the family is differentiated by overhang (L‑D) and interface, so select the body to match the desired geometry.

How should I choose insert size and shank for a new application? Base the selection on required diameter, the expected L/D ratio, machine rigidity and coolant availability; matching the XPMT insert variant and the appropriate TDX drill body is crucial for attaining the planned process reliability.
