TPMT110308-TM AH8015 — ISO turning insert, PVD-coated carbide, 0.8 mm radius (Tungaloy)

TPMT110308-TM AH8015 is an ISO triangular turning insert designed for general machining of heat-resistant alloys, combining a PVD-coated carbide grade with the TM chipbreaker for stable chip control and reliable tool life.

• PVD-coated carbide grade AH8015
• Optimised for heat-resistant alloys
• ISO triangular insert TPMT110308-TM
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for demanding turning operations

The combination of a PVD-coated surface and a purpose-developed carbide grade delivers a measured balance between wear resistance and cutting-edge stability. The AH8015 grade is specified as a first-choice solution for the general machining of heat-resistant alloys because it sustains elevated temperatures while maintaining edge integrity. With a corner radius of 0.8 mm and an included angle of 60°, the insert supports predictable cut geometry and surface finish. Controlled chip formation is assisted by the TM chipbreaker, which reduces the risk of long, stringy chips and improves process reliability across a range of feeds and depths of cut.

Fast integration into ISO tool systems to reduce setup times

Dimensions and mount features adhere to ISO conventions, so mechanical compatibility with matched holders is ensured when form, clearance, tolerance class, fastening method, size and thickness are aligned. The insert’s 3.18 mm thickness and 11° clearance angle provide a robust contact face and adequate clearance to prevent rubbing during external and internal turning. The central cylindrical hole with a one-sided countersink (40°–60°) allows positive, repeatable clamping in standard ISO clamping systems, simplifying changeovers and reducing machine downtime. This geometry supports standardisation on the shop floor and helps maintain consistent process parameters across shifts.

Optimised economy through stable chip control and predictable tool life

Selecting a cutting grade that balances toughness and abrasion resistance reduces the frequency of unexpected edge failures and unscheduled stoppages. The AH8015 composition and the TM chipbreaker encourage stable chip formation, which translates to lower tool inventory turnover and more consistent component quality. For production lines handling heat-resistant alloys, this insert offers an economical compromise: sufficient wear resistance for extended life while retaining edge strength for interrupted or medium-stability cuts. When combined with a correctly matched holder and clamping set, the system supports repeatable results and improved overall process efficiency.

FAQ

What materials is this insert suitable for?
TPMT110308-TM AH8015 by Tungaloy is specified as a first-choice grade for the general machining of heat-resistant alloys, providing a balance between wear resistance and edge stability suitable for many demanding alloys.

Which dimensions and mounting features matter for selection?
Key dimensions are a corner radius of 0.8 mm, insert size 11 mm, thickness 3.18 mm and an 11° clearance angle; the insert fits via a cylindrical hole with a 40°–60° countersink for standard ISO clamping.

How is holder compatibility determined?
Compatibility depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures the TPMT110308-TM seats correctly in the chosen ISO holder and clamp set.

What does the TM chipbreaker do in practice?
The TM chipbreaker promotes controlled chip formation and shorter chip lengths, improving process stability and reducing the risk of chip-related interruptions during turning.

Is this insert better for roughing or finishing?
AH8015 is designed as a general-purpose grade for heat-resistant alloys; its balanced properties make it suitable for both medium finishing and general turning operations, with final selection dependent on workpiece stability and cutting data.
