CPMT 09T302 AH725 — CPMT09T302 AH725 indexable insert for turning (Tungaloy)

CPMT09T302 AH725 is an ISO-standard indexable insert designed for external and internal turning, offering a universal, process-secure grade for steel and stainless steels.

• PVD-coated cemented carbide AH725
• Universal grade for steel and stainless steels
• Rhombic form with 0.2 mm corner radius
• Cylindrical hole with single-sided countersink

Consistent performance across mixed materials

The CPMT09T302 insert is specified for turning and uses the AH725 PVD-coated cemented carbide grade to deliver reliable results when machining mixed batches. The coating and substrate combination promote stable chip formation and resistance to edge breakage, which translates into fewer interruptions and more predictable cycle times. For operations with varying workpiece materials and smaller tool geometries, this universal grade reduces the need for frequent insert changes while maintaining surface quality on both steel and stainless steels.

Geometry and clamping that reduce vibration and improve repeatability

A well-chosen insert geometry directly affects tool stability. The rhombic form with an 80° cutting angle and 11° clearance provides secure engagement and good visibility of the cutting edge, while the 0.2 mm corner radius supports controlled finishing passes. The insert is supplied with hole and a cylindrical hole plus one‑sided countersink (40°–60°) to ensure consistent locating and clamping in standard ISO-compatible holders. These design aspects minimise micro-movements at the cutting edge and support repeatable part tolerances.

Productivity benefits through optimised chip control and material breadth

A single-sided chipbreaker matched to the AH725 grade promotes predictable chip flow and reduces the risk of built-up edge during interrupted cuts. The combination of chip control and the cemented carbide substrate enables higher process reliability, particularly on medium-duty turning tasks where tool life and surface integrity are priorities. Conformance to ISO-standard dimensions ensures quick replacement in existing tool systems and simplifies tool management on the shop floor, contributing to overall productivity gains and lower process variability.
