CPMT09T308 T6215 — ISO turning insert CPMT 09T308 for stainless steel by Tungaloy

The CPMT09T308 T6215 is an ISO‑standard rhombic turning insert designed for general external and internal turning of stainless steel under stable to lightly interrupted conditions.

• CVD-coated carbide T6215
• Optimised for stainless steel turning
• ISO-standard rhombic insert, 80°
• Cylindrical hole with single-sided countersink

Longer tool life through specialised coating and grade

The combination of a CVD coating and a wear‑resistant carbide substrate in grade T6215 provides enhanced abrasion resistance and consistent performance when turning stainless steel. Chemical vapour deposition (CVD) forms a dense ceramic layer over the carbide that reduces flank wear and maintains the integrity of the cutting edge at moderate cutting temperatures. For production contexts where tool life and predictable replacement intervals matter, this insert reduces unscheduled downtime and supports a steady machining rhythm.

Guaranteed fit and system compatibility for predictable processes

Supplied in the ISO CPMT format, the insert matches holders according to form, clearance angle, tolerance class, fastening, size and thickness. Key dimensions — 80° included angle, 11° clearance angle, 0.8 mm nose radius and a plate thickness of 3.97 mm — govern clamping and cutting geometry and should be checked against the selected toolholder. The insert’s cylindrical hole with a single‑sided countersink (40°–60°) ensures secure fastening and repeatable positioning in the clamping set. Using components matched to these specifications supports stable cutting forces and reproducible surface finish.

Practical guidance for stainless‑steel turning and chip control

For stainless‑steel applications, select the one‑sided chipbreaker configuration that corresponds to the part rigidity and feed range; the right chipbreaker promotes consistent chip formation and prevents built‑up edge. The ISO series is best combined with a suitable external holder or boring bar, a correct underlay or clamp set, and the specified replacement screws for safe operation. Choosing the correct chipbreaker and cutting parameters yields improved surface quality and fewer tool changes, translating into measurable productivity gains on the shop floor.

FAQ

What materials is this insert designed for?
The CPMT09T308 T6215 is designed primarily for machining stainless steel, with the T6215 grade offering wear resistance under stable to lightly interrupted cutting conditions.

Which chipbreaker is fitted and why does it matter?
This insert features a one‑sided chipbreaker; chipbreaker choice affects chip control and surface finish and should be matched to workpiece rigidity and feed to ensure consistent chips.

How does the CVD coating improve performance?
The CVD coating forms a hard, thermally stable layer over the carbide substrate that reduces abrasive wear and helps maintain edge geometry, extending tool life in stainless‑steel turning.

What specifications are critical when pairing a holder?
Key parameters include the 80° rhombic form, 11° clearance angle, insert thickness 3.97 mm, and the hole/countersink style — these determine correct clamping and reproducible cutting geometry.
