TCMT 110302 AH8015 indexable turning insert by Tungaloy — PVD-coated cemented carbide, 60° triangle

A TCMT110302 AH8015 indexable insert designed for ISO-compatible external and internal turning of heat-resistant alloys, offering a stable cutting edge and controlled chip formation

*PVD-coated cemented carbide AH8015
*ISO triangular TCMT 110302, 60° included angle
*0.2 mm corner radius for fine turning
*One-sided chipbreaker with cylindrical hole

Increased productivity on heat-resistant alloys

The combination of a PVD coating with a cemented carbide substrate makes this insert well suited to the general machining of heat-resistant alloys. The AH8015 grade is balanced between wear resistance and edge stability, so tool life and process reliability improve in demanding operations. This benefit translates into longer productive cycles and fewer index changes, supporting a smoother machining flow for series and batch production. The PVD layer reduces flank wear and helps maintain a consistent cutting geometry under elevated temperatures.

Geometry that delivers repeatable surface quality

The triangular form with a 60° included angle and a 0.2 mm corner radius provides a predictable contact geometry, which helps achieve uniform surface finish and dimensional stability. The insert’s 3.18 mm thickness contributes to rigidity at the cutting edge, while the 7° free clearance reduces rubbing and heat transfer to the workpiece. The central cylindrical hole with a single-sided countersink (40°–60°) ensures reliable clamping and straightforward seating in ISO-compatible holders. For users replacing inserts, the ISO designation and standardised dimensions simplify inventory and reduce setup time.

System-level advantages and economical handling

This insert is intended as part of a complete system: ISO indexable plate, matching external holder or boring bar, and the required clamping set and screws. The one-sided chipbreaker supports efficient chip control when machining less ductile or work-hardened alloys, reducing the risk of built-up edge and chatter. Using a standardised insert like this improves tool-change speed and enables consistent process parameters across multiple machines. The resulting reduction in downtime and scrap contributes to measurable cost-effectiveness in the production cycle.

FAQ

Is this insert suitable for finishing operations on heat-resistant alloys?
Yes. The AH8015 grade with a PVD coating is developed for general machining of heat-resistant alloys and offers a compromise between wear resistance and edge stability suitable for finishing when parameters are optimised.

Which holders are compatible with the TCMT110302 geometry?
Compatibility depends on the holder’s seat form, clamping method, size and tolerance class; the ISO designation TCMT 110302 ensures fit with standard ISO triangular external holders and boring bars designed for the same designation.

How does the one-sided chipbreaker affect machining performance?
The one-sided chipbreaker on this insert promotes controlled chip formation for certain feed and depth ranges, reducing the likelihood of long, stringy chips and improving process stability during turning.

Can the insert handle interrupted cuts or unstable setups?
The 3.18 mm thickness and triangular 60° form provide mechanical robustness; however, stability in interrupted cuts also depends on the holder, clamping and machine rigidity. Adjusting cutting data and using a suitable holder is recommended.

What are the benefits of the AH8015 grade compared with uncoated grades?
AH8015’s PVD coating enhances wear resistance at elevated temperatures and preserves edge integrity better than comparable uncoated grades, which can extend life and reduce frequency of index changes for many applications.
