CPMT 09T302 T6215 insert for Turning — Tungaloy

CPMT09T302 is an ISO rhombic turning insert designed for reliable external and internal turning, optimised for stainless-steel applications under stable to slightly interrupted cutting conditions.

• ISO rhombic insert, size 09
• CVD-coated carbide grade T6215
• 0.2 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Consistent wear resistance for stainless-steel turning

The CVD-coated carbide grade provides enhanced wear resistance, making it suitable for continuous operations and short interruptions when machining stainless steel. The chosen coating and substrate combination reduces flank wear and maintains a stable cutting edge, which leads to more predictable tool life and fewer unscheduled tool changes. As a result, process stability improves and production throughput becomes more reliable.

Secure seating and repeatable clamping for accuracy

Designed to ISO dimensions, the rhombic geometry and defined relief ensure precise seating in compatible holders; factors such as form, 11° relief, tolerance class, mounting type, plate size 09, and 3.97 mm thickness determine compatibility. The cylindrical hole with a single-sided countersink (40°–60°) offers secure clamping and uniform screw preload, reducing micro-movements during heavy cuts and supporting repeatable part accuracy across batches.

Productivity gains through optimised chip control and edge form

The one-sided chipbreaker and the T6215 grade promote stable chip formation when turning typical workpiece materials, helping to avoid built-up edge and minimise surface defects. The 0.2 mm corner radius supports fine finishing and dimensional control at moderate feed rates, while the robust cutting edge resists chipping in slightly interrupted cuts. Together, these characteristics reduce rework and deliver consistent surface quality.

Practical selection and system integration advice

For best results, pair the insert with a matching ISO external holder or boring bar, the correct shim or clamp set, and the specified mounting screw. Select the chipbreaker and grade according to workpiece stability and the intended operation (external or internal turning). The insert is part of a straightforward system that simplifies tool changes and helps maintain cycle-time reliability in high-mix or repetitive turning tasks.

FAQ

What materials is this insert suitable for?
The CPMT09T302 insert with T6215 coating is intended primarily for machining stainless steel and similar alloys under stable to lightly interrupted conditions.

Which holder types are compatible with this ISO rhombic insert?
Compatibility depends on holder form, tolerance class, mounting method and plate thickness; use ISO rhombic external holders or boring bars designed for size 09 inserts.

How does the T6215 coating benefit machining?
The T6215 CVD-coated carbide provides improved wear resistance and a stable cutting edge, which helps to extend tool life and maintain surface finish during stainless-steel turning.

What influence does the 0.2 mm corner radius have on part finish?
A 0.2 mm corner radius supports fine surface finishing and better dimensional control at moderate feeds, while still offering some robustness against minor interruptions.

What is the SKU and article number for ordering?
The insert is listed as SKU 6951178-Tungaloy with article number 6951178 (manufacturer SKU TUN6951178).
