SPMT090304 T6215 ISO 90° square turning insert by Tungaloy — for stainless steel turning

The SPMT090304 T6215 is an ISO-standard 90° square indexable insert designed for external and internal turning of stainless steel under stable to slightly interrupted cutting conditions.

• CVD-coated T6215 for stainless steels
• ISO SPMT090304 90° square geometry
• 0.4 mm nose radius for light profiling
• Cylindrical hole with single-side countersink (40°–60°)

Consistent edge life and material suitability for stainless steel turning

The CVD-coated carbide grade T6215 offers wear resistance tailored to the demands of machining stainless steel, making the insert suitable for sustained production runs where flank and crater wear must be controlled. The coating and substrate combination reduces adhesive wear and helps maintain cutting-edge integrity during turning operations, which translates into longer tool life and predictable regrinding intervals. This results in a more efficient process with fewer unscheduled tool changes and a steadier component quality.

Designed for secure mounting and ISO compatibility

Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert conforms to ISO dimensions and is therefore suitable for many standard external tool holders and boring bars. The system build comprises the ISO insert, a matching outer holder or boring bar, a shim/clamp set and replacement screws. The 90° square shape and 3.18 mm thickness deliver mechanical stability in the clamped joint, while the cylindrical hole with a single-side countersink (40°–60°) ensures proper seating and repeatable positioning in the cutter body.

Controlled chip formation and fine-surface capability

With a single-sided chipbreaker and a modest 0.4 mm nose radius, the insert balances surface finish and tool robustness for common turning applications. The chipformer and grade selection support chip control tailored to the workpiece material and machining parameters, reducing the risk of built-up edge during stainless-steel turning and improving process reliability. In practice, this means fewer interruptions, consistent surface quality and a reduced need for secondary finishing operations.

FAQ

What materials is this insert intended for?
The SPMT090304 T6215 insert is designed primarily for machining stainless steel under stable to slightly interrupted cutting conditions and is optimised through the CVD-coated T6215 grade for improved wear resistance.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder form, relief angle, tolerance class, fastening and size; the SPMT090304 conforms to ISO dimensions and is compatible with standard 90° square external holders and boring bars when matched with the correct shim/clamp set.

How does the chipbreaker affect performance?
The single-sided chipbreaker on this insert promotes consistent chip formation for many turning tasks, improving process reliability and contributing to a better surface finish when paired with appropriate cutting data for stainless steel.

What mounting features ensure repeatable positioning?
The insert has a cylindrical hole with a single-side countersink (40°–60°) that ensures secure seating and repeatable positioning in the cutter body; the plate thickness of 3.18 mm adds stiffness in the clamped joint.
