CPMT09T304 AH725 Tungaloy indexable turning insert — PVD-coated carbide, 0.4 mm nose radius

The CPMT09T304 AH725 Tungaloy indexable insert is designed for ISO-standard turning applications, offering a universal, fracture-resistant grade for a range of steels and stainless steels

• ISO rhombic insert CPMT09T304, rhombic 09
• PVD-coated carbide AH725 for steels
• 0.4 mm nose radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Stable machining with a universal PVD-coated grade

The CPMT09T304 AH725 insert features a PVD-coated carbide substrate in the AH725 grade, developed for dependable performance across varying workpiece materials. This universal grade AH725 combines fracture resistance with consistent edge stability, resulting in stable chip control and reduced risk of unexpected insert failure. For workshops handling mixed batches of alloyed and non-alloyed steels, the grade’s adaptability supports dependable cycle times and lower process variability.

Precision geometry for consistent surface quality

A small 0.4 mm nose radius and the 11° clearance angle yield a balanced compromise between strength and finish capability. The rhombic geometry with an 80° approach gives a predictable cutting angle for turning operations, allowing for accurate dimensional control and repeatable part surfaces. These geometric attributes reduce the need for corrective rework and help maintain tolerances on turned components, particularly in finishing passes and where tight surface requirements apply.

System compatibility and secure clamping for production

As an ISO-standard insert, compatibility depends on form, clearance angle, tolerance class, attachment, size and thickness; the CPMT09T304 matches common holders when these parameters align. The insert is supplied with a cylindrical hole plus a single-side countersink (40°–60°) and a plate thickness of 3.97 mm, ensuring secure seating and torque transmission in standard clamping systems. Such features simplify tool changeovers and reduce the risk of misalignment during high-speed or interrupted cutting.

Application focus and economic benefit

Intended primarily for external and internal turning, this indexable insert works best when the chipbreaker and grade are matched to the material, operation and machine stability. The AH725 grade’s resistance to chipping and broad material suitability makes it a pragmatic choice for job shops and production lines that prioritise uptime and consistent output. By combining a robust grade with precise geometry, the insert contributes to fewer tool changes and improved machine utilisation, supporting cost-efficient production over time.
