CCMT 09T304 AH8015 indexable turning insert (ISO) – for turning (Tungaloy)

The CCMT 09T304 AH8015 is an ISO rhombic indexable insert designed for general turning of heat‑resistant alloys and stable production environments

• CCMT 09T304 AH8015 PVD-coated carbide insert
• Rhombic CCMT geometry, 80° cutting angle
• 0.4 mm corner radius for medium finishing
• Single-sided chipbreaker for heat-resistant alloys

Engineered for consistent machining of heat-resistant alloys

The insert is built on a PVD-coated carbide substrate in the AH8015 grade to offer a balanced combination of wear resistance and edge stability when machining heat‑resistant alloys. This material pairing reduces flank and crater wear under elevated cutting temperatures, which extends tool life and lowers regrinding or replacement intervals. The formulation is suitable for general turning tasks where a compromise between productivity and surface quality is required; the PVD layer further improves oxidation resistance and adhesion between chip and tool, helping to maintain a stable cutting edge during medium‑duty production runs.

Robust geometry and secure clamping reduce setup time

The rhombic CCMT form with an 80° cutting edge and a 7° relief angle provides versatile cutting orientation for external and internal turning while maintaining good strength at the cutting edge. A thickness of 3.97 mm and the central hole with a cylindrical bore plus a one‑sided countersink (40°–60°) enable consistent clamping in compatible holders and reduce micro‑movement during cutting. Because compatibility depends on form, relief angle, tolerance and thickness, this ISO format integrates with standard CCMT holders and clamping systems, which simplifies inventory and shortens setup time on the shop floor.

Optimised chip control and surface finish for production efficiency

A single‑sided chipbreaker matched to the grade promotes predictable chip formation on steels and alloys that tend to work‑harden; combined with a 0.4 mm corner radius, the insert delivers a balanced surface finish at moderate feeds while limiting cutting forces. The geometry supports both finishing and light roughing passes, so fewer tool changes are necessary across mixed batches. In production terms this means more uptime, fewer interventions and improved repeatability—factors that convert directly into lower unit costs and steadier part quality in serial machining.

FAQ

What materials is this insert suitable for?
The CCMT 09T304 AH8015 indexable insert (Tungaloy, SKU 6825783-Tungaloy) is optimised for machining heat‑resistant alloys and offers a good balance of wear resistance and edge stability for general turning tasks.

Can this insert be used for internal as well as external turning?
Yes, the rhombic CCMT form and the 80° cutting orientation allow the insert to be used for both external and internal turning operations when paired with a compatible holder.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius gives improved tool robustness and is suitable for achieving a medium surface finish while enabling stable cutting at moderate feeds.

What benefits does the AH8015 grade provide?
The AH8015 PVD‑coated carbide grade combines wear resistance with edge stability, helping to extend tool life and maintain consistent part quality under elevated temperatures.

Is the insert compatible with standard CCMT holders?
The insert follows ISO CCMT dimensions and, given matching form, relief angle and thickness (3.97 mm), it is compatible with standard CCMT holders and clamping systems.
