TPMT 130308 AH6235 — Turning insert (ISO) by Tungaloy

A TPMT 130308 AH6235 ISO-standard triangular indexable insert for external and internal turning, designed for rostfreier Stahl and applications with elevated breakout risk.

• PVD-coated carbide grade AH6235
• 11° clearance angle for stable cutting
• Triangular 13 mm insert with 0.8 mm radius
• Countersunk cylindrical hole for secure mounting

Maximise cutting reliability with the right grade and geometry

The combination of a PVD-coated carbide substrate and the AH6235 grade provides an enhanced edge integrity designed specifically for demanding turning tasks such as interrupted cuts and machining of rostfreier Stahl. The PVD layer reduces built-up edge and improves wear resistance, while the 0.8 mm corner radius helps to distribute cutting forces and reduce the tendency for chipping during unstable cuts. With a plate thickness of 3.18 mm and a nominal size of 13 mm, this triangular insert balances stiffness and accessibility for both external and internal turning operations. The result is a measurable improvement in process stability and more consistent component finishes.

Easy integration into ISO systems and choice guidance for applications

As an ISO-standard indexable insert, the part integrates with compatible external holders or boring bars; compatibility is governed by insert form, clearance, tolerance class, fixing, size and thickness. The PM chipbreaker suits a range of turning strategies and should be selected according to workpiece rigidity and cutting conditions. For users uncertain about holder matching or chipbreaker selection, guidance is available to ensure the insert functions as part of a complete tooling system—including shim/clamp sets and replacement screws—so that tool changeover remains efficient and predictable.

Practical benefits: mounting, maintenance and predictable results

The triangular form offers three usable cutting edges, allowing cost-effective indexing. The cylindrical hole with a single-sided countersink (40°–60°) secures the insert reliably in many ISO clamping systems and supports repeatable seating. With a nominal included angle of 60° and an 11° clearance angle, the geometry reduces rubbing and helps maintain cutting-edge integrity across production runs. Backed by Tungaloy manufacturing standards, this insert offers stable chip formation and long tool life, supporting productive turning with consistent outcomes.

FAQ

Which materials is this insert suited for?
The TPMT130308-PM AH6235 indexable turning insert from Tungaloy is optimised for rostfreier Stahl and is well suited to interrupted cutting where edge robustness is required.

How many usable cutting edges does the insert provide?
The triangular shape gives three cutting edges per indexable insert; the TPMT130308-PM AH6235 allows cost-effective re-indexing to prolong tool life.

What chipbreaker is fitted and when should it be chosen?
This insert features a PM chipbreaker; select the PM variant for a balance of chip control and adaptability to varying workpiece stability during turning.

How is the insert secured in the holder?
The TPMT130308-PM AH6235 uses a cylindrical hole with a single-sided countersink (40°–60°) for positive seating in compatible ISO clamping systems; compatibility depends on insert form, clearance and tolerance class.
