CCMT 120408 AH8015 Wendeplatten - Tungaloy

Reliable, productive turning is achievable by combining the PVD-coated AH8015 carbide grade with a 0.8 mm nose radius and secure clamping via the cylindrical hole with countersink; this mix delivers balanced wear resistance, stable cutting edges and repeatable surface quality.

CCMT 120408 AH8015 Turning Insert — Tungaloy, PVD-coated carbide, 0.8 mm radius

CCMT120408 AH8015 is an ISO-form turning insert designed for external and internal turning of heat-resistant alloys and general-purpose applications

• ISO rhombic plate CCMT form
• PVD-coated carbide AH8015 grade
• 0.8 mm nose radius for fine turning
• Cylindrical hole with 40°–60° countersink

Consistent performance for heat-resistant alloys and mixed materials

The AH8015 PVD-coated carbide grade provides a deliberate balance between wear resistance and cutting-edge stability, making it a reliable option for machining heat-resistant alloys and a wide range of steels. The PVD layer enhances surface hardness and thermal resistance while preserving edge integrity under intermittent loads. This results in longer insert life and fewer indexings, contributing to process stability and reduced cycle interruptions. Selecting the correct chipbreaker and grade for the workpiece material supports efficient chip control and predictable tool life.

Secure clamping and straightforward holder compatibility

Compatibility with toolholders is governed by form, clearance angle, tolerance class, fastening, size and thickness; the rhombic CCMT geometry and the cylindrical hole with single-sided countersink (40°–60°) ensure positive seating and repeatable orientation in compatible external holders or boring bars. The ISO standardised designation simplifies holder selection and reduces setup time. The supplied dimensions—plate size and thickness—allow quick verification against holder specifications, enabling a secure, vibration-resistant assembly that supports stable cutting conditions.

Fine surface finishes and dimensional repeatability

The combination of an 0.8 mm nose radius, an included cutting angle of 80° and a 7° clearance promotes fine finishing capability while maintaining sufficient edge strength for light to medium machining. A modest nose radius helps achieve tighter surface roughness values and consistent form tolerances without sacrificing the robustness required in production environments. Where finishing and finishing-plus-roughing steps are required, this insert geometry offers a predictable compromise between material removal and surface quality.

Efficient process integration for higher throughput

As an indexable, ISO-format insert made from carbide with a PVD coating, the component integrates readily into multi-station turning cells and standard toolholder systems. The single-sided chipbreaker supports controlled chip formation for a variety of feeds, reducing risk of built-up edge and improving coolant interaction at the cutting zone. Fewer tool changes and consistent cutting performance translate into improved machine uptime and overall process economy. For process planning, note the typical system: the ISO insert, a matching external holder or boring bar, a support shim or clamp set, and replacement fastening screws.

FAQ

What materials is this insert intended for? The CCMT120408 AH8015 insert is specified for general machining of heat-resistant alloys and a broad range of steels, offering a balanced mix of wear resistance and edge stability.

How does the PVD coating affect cutting performance? The PVD coating on the AH8015 grade improves thermal resistance and surface hardness, which supports longer tool life and more consistent edge behaviour when the insert is used in turning operations.

Is the insert compatible with standard ISO CCMT holders? The insert follows ISO form and dimensions; compatibility is determined by holder form, clearance, tolerance class, fastening method, size and thickness—ensure the holder matches the ISO CCMT120408 geometry.

What chip control can be expected from the single-sided chipbreaker? The single-sided chipbreaker provides controlled chip formation for a range of feeds, aiding coolant action and reducing the likelihood of built-up edge during intermittent or continuous turning.

How does the 0.8 mm nose radius influence surface finish? A 0.8 mm radius provides a favourable compromise between surface finish and edge strength, enabling finer finishes and repeatable dimensional results in finishing and semi-finishing passes.
