TPMT 130308 AH6235 triangular turning insert — PVD-coated carbide, 0.8 mm corner radius (Tungaloy)

TPMT130308-PSS AH6235 is a triangular ISO turning insert designed for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated AH6235 grade for stainless steel
• Triangular shape for stable seating
• Cylindrical hole + 40°–60° countersink
• 0.8 mm corner radius for general turning

Precision and predictable performance for stainless-steel turning

The PVD-coated carbide specification delivers a tougher cutting edge that better resists chipping in interrupted cuts and on difficult-to-machine, stainless steels. The insert’s ISO geometry and triangular form provide consistent seating and repeatable indexation, which reduces set-up time and supports stable machining cycles. By choosing this grade, process planners gain a combination of edge robustness and dimensional predictability that lowers scrap risk during series turning.

Compatibility and setup explained for efficient tool selection

Compatibility with the toolholder depends on form, relief angle, tolerance class, fastening method, size and thickness; the plate thickness of 3.18 mm and the standard 60° included angle make the insert suitable for many ISO triangular holders. The insert’s 11° relief angle improves clearance and reduces rubbing on the flank, helping to maintain surface finish even under variable cutting conditions. Selecting the correct chipbreaker (PSS) and grade (AH6235) ensures effective chip control and longer edge life in intermittent cuts.

Practical benefits: productivity, repeatability and reduced downtime

A consistent corner radius of 0.8 mm provides a balance between edge strength and profile accuracy, allowing for stable feed rates and predictable tool life. The combination of the PVD-coated carbide and a purpose-designed chipbreaker reduces the incidence of built-up edge and unexpected edge failure, which in turn supports higher uptime and fewer tool changes. For production environments aiming to improve throughput without compromising part quality, this insert offers a pragmatic route to more reliable turning cycles.

FAQ

What materials is this insert intended for?
The TPMT130308-PSS AH6235 insert is specified for stainless steels and is particularly effective in interrupted cuts or situations with higher chipping risk.

Which holders are compatible with this ISO insert?
Compatibility is determined by holder form, relief angle, tolerance class, fastening, size and thickness; the ISO geometry of this insert matches standard triangular turning holders designed for 13 mm inscribed circle plates.

How does the AH6235 grade affect tool life?
The AH6235 PVD-coated carbide grade offers improved resistance to chipping and wear in demanding stainless-steel turning, which typically extends effective tool life and reduces unscheduled changes.

What advantage does the 0.8 mm corner radius provide?
A 0.8 mm corner radius balances edge strength and profile accuracy, enabling stable feeds and improved surface finish while limiting vulnerability to edge breakouts.

Is this insert suitable for finishing operations?
With the PSS chipbreaker and the specified geometry, the insert can be used for general turning; for high-precision finishing, cutter and parameter selection should be matched to the desired surface tolerance and feed rates.
