CPMT09T304 T6215 CPMT ISO 09T304 T6215 rhombic turning insert (Tungaloy)

CPMT09T304 T6215 is an ISO-format rhombic indexable insert engineered for stable external and internal turning of stainless steels, offering reliable chip control and long tool life.

• ISO rhombic insert, size 09
• CVD-coated carbide grade T6215
• Optimised for turning stainless steel
• Cylindrical hole with single-side countersink

Consistent cutting performance for stainless steel turning

The CVD-coated carbide composition of this grade delivers predictable wear behaviour under stable to slightly interrupted cut conditions, translating into longer intervals between index changes and less downtime. With a 0.4 mm nose radius and a 3.97 mm plate thickness, the geometry balances edge strength and cutting agility, enabling controlled engagement on both roughing and finishing passes. The combination of Tungaloy metallurgy and tight ISO tolerances supports repeatable results on demanding stainless steel alloys, reducing scrap rates and stabilising cycle times.

Designed for secure mounting and broad machine compatibility

The insert follows ISO standards for form and tolerances, so compatibility depends on holder form, relief angle and fastening method rather than proprietary dimensions. The CPMT rhombic shape with an 80° diamond and a 11° clearance angle ensures robust seating in standard external holders or boring bars. The insert is supplied with a cylindrical fixing hole and a one-sided countersink (40°–60°) to match common clamping systems, simplifying inventory management and making it straightforward to pair the grade with existing holders for diverse turning tasks.

Improved chip control and predictable surface quality

An asymmetric, one-sided chipbreaker on the insert helps manage swarf formation when machining stainless steels, where stringing and workhardening can otherwise hinder productivity. The T6215 grade combines a wear-resistant CVD coating with a carbide substrate that maintains a sharp, stable cutting edge; this results in more consistent surface finishes and fewer secondary operations. For operations prioritising throughput, the insert contributes to higher first-pass yield and reduced tool changes, thereby supporting a more efficient machining process.

FAQ

What materials is this insert intended for?
The CPMT09T304 T6215 insert is formulated for machining stainless steels; the T6215 CVD-coated carbide provides wear resistance and reliable edge retention in such alloys.

Which clamping systems fit this insert?
The insert uses ISO-standard geometry with a cylindrical fixing hole and a single-side countersink (40°–60°), so it fits holders designed for CPMT-style inserts and standard ISO clamping arrangements.

How does the chipbreaker behave on interrupted cuts?
The one-sided chipbreaker supports stable swarf control under stable to lightly interrupted cutting; the design reduces stringing and helps maintain consistent surface quality.

Can this insert be used for both external and internal turning?
Yes — the rhombic form and 80° included angle enable use in both external turning holders and appropriately sized boring bars for internal turning operations.

What identifies the correct replacement insert for a worn edge?
Look for the designation CPMT09T304 with grade T6215 and the manufacturer SKU TUN6945229 to ensure the same geometry, coating and performance characteristics.
