TPMT110304-PSS AH6235 — Indexable turning insert, PVD-coated carbide, 0.4 mm radius (Tungaloy)

A TPMT110304-PSS AH6235 indexable insert intended for external and internal turning, optimised for stainless steel and interrupted cuts with an 11° clearance angle

• PVD-coated carbide grade AH6235
• 0.4 mm corner radius for delicate profiles
• 11° clearance angle for controlled cutting
• Triangular insert with cylindrical hole and countersink

Consistent chip control for stainless steel turning

The PVD coating combined with a carbide substrate and the tougher AH6235 grade provides controlled wear and stable cutting when machining stainless steel and mixed batches. The chipbreaker PSS is engineered to manage short, fragmented chips typical of interrupted cuts, which reduces the risk of built-up edge and unexpected tool failures. Specified geometry and a 0.4 mm corner radius maintain surface integrity when producing fine profiles, so cycle times remain predictable and rework is minimised.

Precision geometry and secure clamping for repeatable results

A triangular ISO insert form with a central hole and a one-sided countersink (40°–60°) ensures reliable seating and clamping in compatible toolholders. The 11° clearance reduces rubbing on the flank face, lowering heat generation and improving edge life during continuous and stop-start operations. With a thickness of 3.18 mm and the ISO designation, compatibility is straightforward: holders are selected by form, clearance, tolerance class, fastening and insert size, enabling reproducible set-ups and minimised downtime.

Process reliability and selection guidance for production environments

The combination of grade AH6235 and the PSS chipbreaker balances toughness and wear resistance, making the insert suitable for applications with elevated breakout risk and varying material batches. For economical productivity, the grade supports stable chip formation across typical stainless alloys, while the triangular shape offers three usable cutting edges per indexable insert, contributing to overall cost-efficiency. Selection of holder stiffness and cutting parameters should match the insert’s properties to exploit its full potential in series production.

FAQ

What materials is this insert suitable for?
The TPMT110304-PSS AH6235 is optimised for stainless steel and performs well in interrupted turning where the tougher AH6235 grade resists edge breakage.

How does the chipbreaker PSS affect machining?
The PSS chipbreaker on the TPMT110304-PSS AH6235 promotes short, controlled chips in stop‑start cuts, improving process security and reducing the chance of chip jams.

What are the key dimensions and mounting details?
The insert has a thickness of 3.18 mm, an insert size of 11 and a corner radius of 0.4 mm; it features a central cylindrical hole with a single-sided countersink for secure clamping.

Can this insert be used for both external and internal turning?
Yes, the indexable design and ISO geometry make the TPMT110304-PSS AH6235 suitable for both external and internal turning when paired with the correct holder.

How many cutting edges are available per insert?
The triangular format provides three cutting edges per insert, offering efficient use of the indexable stock.
