SPMT090308 AH725 – Indexable insert for drilling systems, PVD-coated carbide, 90° (Tungaloy)

SPMT090308 AH725 is a square indexable insert designed for drilling systems, offering a universal, fracture-resistant grade for steel and rostfreier Stahl in demanding production environments

• Universal PVD-coated grade AH725
• Square 09 format with 0.8 mm radius
• Cylindrical hole with 40°–60° countersink
• 11° clearance angle for secure seating

Consistent chip control and material flexibility for reliable cycles

The PVD-coated carbide grade AH725 provides a balance of toughness and wear resistance that improves process security in mixed-material batches. As a universal, break-out resistant grade, it is particularly suited to machining both steel and rostfreier Stahl, reducing the need for frequent insert changes and simplifying tool management. Improved chip control from the single-sided chipbreaker lowers the risk of plug formation and helps maintain stable cutting conditions in short-hole and through-hole drilling alike.

Secure seating and repeatability that stabilise production

With a square 09 format, 0.8 mm corner radius and 3.18 mm plate thickness, the insert offers a compact geometry that supports accurate location in compatible drill bodies. The cylindrical hole with single-sided countersink (40°–60°) and 11° clearance angle ensure reliable clamping and repeatable indexability, which leads to reproducible hole quality and less rework. These mechanical features translate into predictable tool life and fewer interruptions on the shop floor, especially where smaller tools and tight tolerances are required.

Practical application advantages and economical operation

Designed specifically for use in changeable-insert drilling systems, the component integrates into a standard assembly of drill body, clamping screw and driver key, enabling quick replacement and minimal downtime. The combination of a fracture-resistant grade and compact square geometry offers cost-efficiency by extending service intervals and lowering inventory complexity. Production engineers and job-shop managers will value the balance of durability, process stability, and straightforward interchangeability when planning batch runs or mixed-material work.
