TPMT 110304 AH6225 – Tungaloy triangular turning insert, PVD-coated carbide, 0.4 mm radius

The TPMT110304-PSS AH6225 is a triangular ISO turning insert designed for external and internal turning, optimised for medium machining of stainless steel and variable cutting conditions

• PVD-coated carbide grade AH6225
• Universal for stainless steel machining
• 11° clearance, 60° included angle
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless steel turning

The insert combines a PVD-coated surface with the AH6225 carbide grade to deliver a sharp cutting edge alongside stable cutting edge behaviour under fluctuating conditions. This pairing reduces the tendency for built-up edge on stainless workpieces and supports consistent chip formation during medium cutting tasks. The result is a more predictable process, improved surface integrity and fewer unexpected tool changes—benefits that directly support productivity and repeatable part quality.

ISO compatibility and secure clamping for straightforward integration

Built to ISO dimensions, the insert's ISO 110304 designation, triangular form and specific thickness make it compatible with a wide range of triangular external holders and boring bars; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The 0.4 mm radius and the cylindrical hole with single-side countersink (40°–60°) provide secure seating and repeatable location in the clamping pocket. These features simplify tool selection and reduce setup uncertainty when replacing inserts in an established holder system.

Better chip control and reduced downtime through chipbreaker design

Equipped with the PSS chipbreaker, the insert is developed for controlled chip segmentation during both external and internal turning operations. Controlled chips reduce the risk of entanglement and facilitate automated chip evacuation, which cuts handling time and lessens the likelihood of process interruptions. The balanced combination of chip control and a resilient carbide substrate supports longer uninterrupted runs and more consistent cycle times on serial production tasks.

Practical system advice and recommended workflow

A reliable system comprises the insert plus a matching external holder or boring bar, a suitable shim/clamping set and replacement screws. The insert's triangle geometry and 60° included angle allow flexibility in approach angles for many common turning applications. Select the chipbreaker and grade according to workpiece stability and the desired surface finish; lighter clamping or long overhangs call for more conservative cutting parameters. For questions about holder matching or best practice setups, Metav Werkzeuge can advise on compatible clamping components and process parameters to suit specific turning tasks.

FAQ

What materials is this insert intended for? The TPMT110304-PSS AH6225 insert is specified for stainless steel machining; the AH6225 grade and PVD coating support medium turning on a broad range of stainless workpieces.

Is the insert compatible with standard triangular holders? Yes, the insert follows ISO 110304 dimensions; compatibility with a triangular holder is determined by form, clearance, tolerance class, fastening and thickness—confirm fit with the holder manufacturer or Metav Werkzeuge.

What is the purpose of the PSS chipbreaker? The PSS chipbreaker on this turning insert improves chip control and segmentation, which helps maintain process stability and reduces downtime during continuous turning operations.

How does the 0.4 mm corner radius affect the cut? A 0.4 mm radius provides a balance between strength and surface quality, offering improved edge robustness compared with sharper radii while still achieving acceptable surface finishes in medium turning.

Which SKU should be ordered for this Tungaloy insert? Order using SKU 6829890-Tungaloy or Manufacturer SKU TUN6829890 to ensure the correct TPMT110304-PSS AH6225 grade and geometry are supplied.
