CPMT 060204 AH725 – Tungaloy indexable turning insert for ISO turning applications

A CPMT 060204 AH725 insert engineered to ISO standards, offering a universal, break‑resistant grade optimised for external and internal turning of steel and stainless steel.

• ISO-standard CPMT 060204 geometry
• PVD-coated AH725 carbide grade
• Single-sided chipbreaker for reliable chips
• Cylindrical hole with 40°–60° countersink

Consistent fit and predictable clamping for ISO holders

The insert follows an ISO-standard geometry, which ensures reproducible positioning when paired with compatible toolholders and boring bars. Compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness; this means reliable repeatability during index changes and uncomplicated tooling setup. With an 80° approach angle and a 11° relief angle, the geometry supports stable cutting forces and predictable tool engagement, reducing downtime caused by refitting and improving throughput in both short and long series production.

Durable PVD-coated grade for mixed-material production

The AH725 grade is a PVD-coated carbide specifically developed as a universal, chip-resistant option for processing steel and stainless steel. The coating enhances edge life under varying cutting conditions, while the substrate retains necessary toughness to resist chipping on interrupted cuts. For shops handling mixed batches or frequently changing workpiece alloys, this insert provides a balance between wear resistance and toughness, supporting a higher degree of process security without the need for constant grade swaps.

Geometry and features that improve chip control and surface finish

Key design details such as the single-sided chipbreaker, rhombic shape, 0.4 mm corner radius and 2.38 mm thickness contribute directly to machinability and finished-part quality. The single-sided chipbreaker assists in controlled fragmentation and evacuation of swarf, particularly on medium-depth turning, while the 0.4 mm corner radius offers a compromise between strength and edge definition for consistent surface finishes. The central cylindrical hole with a 40°–60° countersink ensures secure clamping and precise seating, supporting repeatable tool indexing and minimising runout-related issues.

Practical guidance for selection and application

Intended for turning operations, the insert is suitable for both external and internal tasks when the correct holder is chosen to match the plate form and tolerance class. Select the chipbreaker and grade based on the workpiece material and the stability of the setup: the AH725 grade suits applications with variable materials and smaller tool sizes where process reliability is a priority. For finishing passes, the smaller corner radius and the insert’s geometry favour improved surface quality; for heavier roughing, consider larger radii or toolpath adjustments to preserve edge life.
