CPMT 09T308 T6215 — ISO indexable turning insert for turning

The CPMT09T308 T6215 is an ISO-format indexable turning insert designed for turning applications, optimised for stainless steel under stable to slightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• ISO rhombic insert, 09 size
• 0.8 mm corner radius
• Suitable for stainless steel turning

Increased process reliability for serial turning

The insert’s CVD-coated carbide composition delivers elevated wear resistance, extending tool life in continuous production. The geometry is engineered for consistent chip control in stable to lightly interrupted cuts, which reduces downtime caused by edge failure and repeated indexing. With an included angle of 80° and an 11° clearance angle, the geometry supports secure engagement and dependable cutting forces, translating to predictable tool performance in moderate-duty turning operations.

Reduced setup complexity through ISO conformity

As an ISO-standard turning plate, the component integrates with common holders and boring bars when the form, clearance angle, tolerance class, fastening method, size and thickness match. The rhombic shape and 09 size simplify selection across a wide range of external and internal turning tasks. The insert’s 3.97 mm thickness and cylindrical hole with a single-sided countersink (40°–60°) ensure a secure clamping interface and repeatable seating, lowering the risk of assembly errors and thereby improving first-part accuracy.

Improved surface quality and tool life for stainless steel

For applications in stainless steel, the T6215 grade offers a balance of toughness and abrasion resistance suited to common stainless alloys. The 0.8 mm corner radius supports edge strength while enabling fine surface finishes on turned components; selecting the correct chipbreaker and grade according to workpiece material and machining stability reduces built-up edge and enhances finish consistency. The result is fewer reworks and more parts meeting specification without additional passes.

Practical system guidance and application notes

The insert is part of a system comprising the ISO indexable plate, a matching external holder or boring bar, a support/shim or clamping kit, and replacement screws. Compatibility depends on matching form factor and tolerances rather than brand alone. For one-off adjustments or process optimisation, choose the chipbreaker and grade that correspond to the specific alloy and cut type; a single-sided chipbreaker is indicated for the supplied geometry to suit conventional turning strategies and moderate feed ranges.

FAQ

What applications suit this indexable insert best?
The CPMT09T308 T6215 insert is intended for external and internal turning operations, particularly turning stainless steel under stable to slightly interrupted cutting conditions.

How does the T6215 grade perform on stainless steel?
The T6215 CVD-coated carbide offers a balance of abrasion resistance and toughness, providing improved tool life and surface quality when machining stainless steel with appropriate feeds and depths of cut.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder matching the insert form, clearance angle, tolerance class, fastening style, size and thickness; the CPMT09T308 sits in standard ISO rhombic holders sized for 09 inserts.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with a single-sided countersink (40°–60°) ensures stable, repeatable clamping and simplifies replacement with standard screw/clamp kits.
