SPMT090304 AH6235 SPMT 090304 turning insert for stainless steel by Tungaloy

The SPMT090304 AH6235 is an ISO-standard turning insert designed for external and internal turning operations, optimised for interrupted cuts and applications with increased breakout risk.

• PVD-coated carbide AH6235 for stainless steel
• ISO SPMT090304 geometry, 90° shape
• 0.4 mm corner radius for edge strength
• Cylindrical hole with one-sided countersink

Precise design for reliable turning results

The insert delivers a consistent cutting edge thanks to its PVD-coated carbide composition and the AH6235 tough grade, which is formulated specifically for applications in stainless steel and conditions with interruption risk. The combination of coating and substrate offers improved wear resistance and edge stability; this reduces the need for frequent index changes and contributes to a more predictable tool life. The result is a measurable improvement in process stability and fewer unplanned interruptions.

Improved chip control and edge security

A well-chosen single-sided chipbreaker paired with the 0.4 mm corner radius and 90° geometry ensures controlled chip formation and robust edge support during heavier cuts or interrupted machining. These geometric choices lower the likelihood of edge collapse and support a repeatable surface finish, so operators can expect reliable part quality even when machining challenging batches. The insert’s features are aimed at maintaining cutting performance and reducing secondary operations.

Compatibility and secure mounting for production use

As an ISO-compliant indexable insert, the component fits holders matching its form, relief angle and tolerance class; compatibility depends on the holder’s geometry, fastening method, size and thickness. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) to secure positive clamping and correct seating in most standard external holders and boring bars. The 3.18 mm thickness and standard size designation support repeatable clamping forces and minimise micro-movements during machining.

Application focus and productivity gains

Engineered for turning tasks, the grade and construction are particularly suited to machining stainless steel under intermittent conditions where fracture resistance and chip control are critical. The PVD-coated surface extends tool life and helps maintain cutting-edge integrity, which translates into reduced tool change frequency and higher uptime. Choosing this insert supports efficient workflows and contributes to predictable batch times in production environments.
