RCMT2507M0-RS AH8005 Tungaloy turning insert — ISO 2507M0, PVD-coated carbide

A RCMT2507M0-RS AH8005 Tungaloy insert engineered for external and internal turning of heat-resistant alloys and hard materials in stable machining setups

• PVD-coated carbide grade AH8005
• For heat‑resistant alloys and hard materials
• ISO round insert, 25 mm diameter, 7.94 mm thick
• Cylindrical hole with single‑side countersink

Longer tool life through optimised coating and substrate

The indexable insert is supplied in a PVD-coated cemented carbide grade designed for elevated temperatures and abrasive conditions. The AH8005 grade provides a balance between wear resistance and toughness, so the insert maintains cutting-edge integrity during sustained cuts in demanding alloys. Paired with the chipbreaker RS, the geometry controls chip flow under stable setups, reducing the frequency of tool changes and improving overall process economy. This translates into fewer machine stops and predictable batch output when compared with uncoated or lower-grade alternatives.

Predictable clamping and dimensional conformity for repeatable finishes

Compliant with ISO form and size conventions, the round insert presents a 25 mm nominal size and a plate thickness of 7.94 mm, matched to the ISO code 2507M0. A 7° clearance angle and a cylindrical hole with a single‑side countersink (40°–60°) allow secure engagement in standard clamping systems and reduce the risk of micro‑movement during machining. Compatibility to specific holders is defined by form, clearance, tolerance class, fastening method, size and thickness; selecting a correctly rated external holder or boring bar and the appropriate shim/clamp set ensures repeatable surface quality and minimises vibration that would otherwise affect dimensional accuracy.

Practical guidance for application and system setup

Typical use covers external and internal turning where stable cutting conditions prevail. Choice of chipbreaker and grade should follow the workpiece material and the rigidity of the machining setup: the RS chipbreaker is suited to controlled chip formation under steady feed and depth of cut. The insert forms part of a system that includes a matched holder, underlay/clamp set and replacement screws for safe mounting. For economical operation, match the insert to a holder with correct seat geometry and apply the recommended clamp torque; this protects the cutting edge, prolongs lifetimes and helps maintain consistent component tolerances. Technical consultation is available for optimising insert selection for a given workpiece and machine combination.

FAQ

What materials is this insert suitable for?
The RCMT2507M0‑RS AH8005 Tungaloy insert is specified for heat‑resistant alloys and hard materials, offering wear resistance in demanding turning operations.

How does the insert secure to a holder?
Clamping is achieved via the cylindrical hole with a single‑side countersink; compatibility with a specific holder depends on form, clearance, tolerance class, fastening method, size and thickness of the assembly.

What does the AH8005 designation indicate?
AH8005 denotes a PVD‑coated cemented carbide grade optimised for wear resistance at elevated temperatures while retaining sufficient toughness for stable cuts.

Is the RS chipbreaker suitable for roughing operations?
The chipbreaker RS is intended to control chip formation in stable machining contexts; suitability for heavy roughing depends on machine rigidity and selected cutting parameters.

Which components are required to build a complete cutting system?
A complete system generally comprises the indexable insert, a compatible external holder or boring bar, an underlay/clamp set and the appropriate replacement screws for secure mounting.
