TPMT 16T312 AH6235 indexable turning insert — PVD-carbide, 60° (Tungaloy)

A TPMT 16T312 AH6235 indexable insert engineered for external and internal turning, designed specifically for stainless steels and applications with elevated breakout risk.

• PVD-coated carbide for tough stainless steels
• Optimised PM chipbreaker for interrupted cuts
• ISO TPMT 16T312 triangular insert, 60°

Consistent performance where interruptions occur

The insert delivers reliable cutting in demanding conditions thanks to its PVD-coated carbide grade AH6235, a tougher substrate formulated for stainless steels and operations with increased risk of edge chipping. The PM chipbreaker promotes predictable chip formation, reducing the likelihood of unexpected tool damage during interrupted cuts. For production environments, this combination means fewer unscheduled tool changes and steadier component quality, supporting higher process uptime and lower scrap rates.

Precision geometry for repeatable form and surface quality

Geometry and dimensions translate directly into part conformity: the triangular 16 mm format with a 1.2 mm corner radius provides a stable cutting edge for external profiles and light finishing passes, while the 60° insert angle supports standard turning holders. The 11° relief angle helps to control cutting forces and deflection, and the 3.97 mm plate thickness contributes to rigidity in the clamping assembly. These mechanical characteristics allow predictable tool behaviour, which simplifies parameter selection and reduces trial runs when setting up new operations.

Easy integration and tailored application guidance

Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; the insert is supplied with a cylindrical hole and single-sided countersink (40°–60°) to match common clamping systems and ensure secure locking. The product is intended for use with a matching external holder or boring bar and requires the appropriate shim or clamp set plus replacement screws for assembly. For manufacturers seeking a balance of process reliability and cost-effective machining, the insert’s combination of coating, chipbreaker and geometry offers predictable tool life across a broad range of stainless steel grades.

FAQ

What materials is this insert suited for?
The TPMT 16T312 AH6235 insert is formulated for stainless steels and applications where toughness and resistance to chipping are required.

Which chipbreaker does the insert feature and what advantage does it provide?
The insert uses a PM chipbreaker, which improves chip control during interrupted cuts and reduces the risk of edge breakout in demanding operations.

How is compatibility with toolholders determined?
Compatibility is defined by holder form, free angle, tolerance class, fastening method, size and thickness; ensure the clamping system matches the TPMT16T312-PM geometry.

What are the key dimensional references to check before ordering?
Check insert size (16 mm), plate thickness (3.97 mm), corner radius (1.2 mm), relief angle (11°) and the 60° main angle to ensure fit and function.
