CPMT 080204 AH725 — Tungaloy ISO turning insert, 80° rhombic, PVD-coated carbide

The CPMT080204 AH725 is an ISO-format turning insert engineered for external and internal turning, delivering fracture-resistant performance and consistent chip control in demanding production environments

• ISO rhombic insert CPMT 080204, 80°
• PVD-coated carbide AH725 for steel & stainless
• Single-sided chipbreaker for consistent chips
• With cylindrical hole and 40°–60° countersink

High-process security through material and coating

Designed for secure, productive turning applications, the CPMT080204 AH725 combines a PVD-coated carbide substrate with a fracture-resistant composition optimised for a wide range of steels and stainless steels. As a universal grade, AH725 offers a balanced compromise between toughness and wear resistance, making it particularly suitable for mixed-material production and smaller tooling where process security is critical. The outcome is stable chip formation, extended edge life and fewer insert changes, which supports continuous operation and reduces unplanned downtime.

Geometry that stabilises cutting and improves finish

The rhombic 80° profile with a 0.4 mm corner radius provides a robust entry geometry that maintains edge strength while enabling precise cutting engagement for external and internal turning. The single-sided chipbreaker is tuned to direct chips consistently, lowering the risk of jamming and reducing secondary operations. Combined with an 11° relief and a plate thickness of 2.38 mm, the geometry enhances mechanical rigidity, permitting more predictable feeds and improved surface quality with reduced chatter on less rigid setups.

ISO standardisation and system-level advantages

The insert adheres to ISO conventions for form and size, which simplifies selection and replacement in standard turning tool systems. The integrated cylindrical hole with 40°–60° countersink ensures secure clamping and repeatable positioning in compatible holders, while the rhombic shape allows flexible approach angles for a range of turning tasks. When paired with the correct external holder, clamping set and replacement screws, this indexable insert contributes to a dependable cutting system that optimises cycle times and tool-change routines.

FAQ

What materials is this insert suitable for?
The CPMT080204 AH725 Tungaloy turning insert (SKU TUN6865197) is designed primarily for steel and stainless steels; the fracture-resistant AH725 grade handles variable materials commonly encountered in mixed-production environments.

What are the key geometry specifications?
The insert features an 80° included angle with a 0.4 mm corner radius, an 11° relief angle and a plate thickness of 2.38 mm, delivering a balance of edge strength and cutting precision.

Can this insert be used for internal turning?
Yes — the rhombic 80° geometry and compact profile make the insert suitable for internal turning when combined with an appropriate internal turning holder and correct clamping.

What coating and grade does the insert use?
This indexable insert uses a PVD-coated carbide substrate in grade AH725, chosen for its universal, breakout-resistant behaviour and reliable performance across a wide material range.

How does the chipbreaker influence machining behaviour?
The single-sided chipbreaker on this insert promotes consistent chip formation and evacuation, reducing the risk of built-up edge and improving operational uptime and surface finish.
