CCMT120404 AH8015 ISO rhombic turning insert for general turning — Tungaloy

CCMT120404 AH8015 is an ISO-format rhombic insert designed for external and internal turning of heat-resistant alloys and general-purpose steel applications.

• ISO rhombic insert CCMT 120404
• PVD-coated carbide grade AH8015
• 0.4 mm corner radius for finishing
• Cylindrical hole with 40°–60° countersink

Robust grade and coating for heat-resistant alloys

The PVD-coated AH8015 grade combines a wear-resistant surface with a stable cutting edge, making it a sound choice for machining temperature-resistant alloys. The PVD coating reduces flank wear and helps maintain cutting geometry over longer cycles, which translates into fewer insert changes and more predictable machining. For users moving from uncoated grades, this insert offers a noticeable improvement in life expectancy without sacrificing edge stability, so production runs remain consistent and downtime is reduced.

ISO compatibility and secure clamping for efficient set-up

Built to the ISO designation CCMT120404, the insert matches standard rhombic holders when form, clearance angle, tolerance class, fixation and thickness align. The 7° clearance angle and a plate thickness of 4.76 mm ensure rigid support in the seat, while the cylindrical hole with single-sided countersink (40°–60°) provides positive, repeatable clamping. This standardised fitment reduces set-up time and simplifies spare-part management across tool systems, supporting uninterrupted workflow on the shop floor.

Predictable surface finish thanks to small corner radius

The 0.4 mm corner radius is tuned for fine finishing and reproducible part geometry on external and internal contours. A smaller radius reduces cutting forces during light passes, promoting a consistent surface finish and minimising vibration in less rigid set-ups. When combined with the appropriate one-sided chipbreaker and the AH8015 grade, the insert achieves a balance between edge strength and the capacity to produce tight tolerances on turned features—valuable in precision components and batch production alike.

Practical system approach for everyday turning tasks

The insert is intended for general turning operations and integrates into a system comprising a compatible external holder or boring bar, a shim or clamp set and replacement screws. Selecting the right chipbreaker and grade for the workpiece material is essential: the AH8015 grade is a first choice for heat-resistant alloys, offering a compromise between wear resistance and edge robustness. By using standard ISO inserts within a complete system, tool inventory is simplified and tool-change procedures become faster, supporting higher throughput and stable machining results.
