SCMT 09T304 T6215 ISO turning insert for stainless-steel turning — Tungaloy

The SCMT09T304 T6215 is an ISO-standard square insert designed for external and internal turning, optimised for stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide for high wear resistance
• Single-sided chipbreaker for reliable chips
• Square 09 size, 7° relief angle
• 0.4 mm corner radius for precise profiles

Prolonged tool life through a wear-resistant coating

The combination of a CVD-coated surface with a robust carbide substrate gives the insert clear advantages in abrasive and adhesive wear scenarios common with stainless steels. The applied coating reduces flank and crater wear, which leads to longer cutting edge life and fewer index changes; this improves process stability and lowers overall machine downtime. For production contexts where consistent finish and predictable tool performance matter, the coated grade offers quantifiable gains in uptime and repeatability.

Predictable geometry for secure clamping and surface integrity

ISO conformity and the square 09 format ensure straightforward integration into standard holders and boring bars; the insert's 7° relief and 90° included angle support accurate profile generation and repeatable part geometry. The 0.4 mm corner radius provides a balance between edge strength and the ability to produce defined contours, while the central cylindrical hole with a single-sided countersink (40°–60°) enables firm, repeatable clamping. These geometric choices improve chip control and surface finish when paired with a compatible clamping set and replacement screws.

Practical workshop benefits and application guidance

Built for turning operations, the insert performs best under stable cutting conditions or light interruptions; choose toolholders and feed rates that match machine rigidity to exploit the grade's strengths. The single-sided chipbreaker helps manage swarf in common external and internal turning tasks, reducing rework and enhancing operator safety. The insert is part of a typical system comprising an ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws — a configuration that supports efficient changeover and keeps inventories manageable.

FAQ

Is this insert suitable for stainless-steel turning?
Yes. The SCMT09T304 T6215 indexable insert from Tungaloy is formulated for turning stainless steels under stable to lightly interrupted conditions, offering enhanced wear resistance and consistent edge life.

Can the insert handle interrupted cuts?
The grade is optimised for stable cutting and light interruptions; for heavy interruptions, consider a geometry and holder setup with higher rigidity to protect the edge from shock loads.

Which holders are compatible with this insert format?
ISO-compliant square 09 external holders or boring bars that accept a square SCMT insert with a central hole and countersink are compatible; correct matching of form, clearance and tolerance class is essential for secure clamping.

How does the single-sided chipbreaker influence performance?
A single-sided chipbreaker promotes consistent chip formation and evacuation in turning stainless steels, reducing the risk of entanglement and improving surface finish when combined with appropriate feeds and speeds.

What mounting features need attention during installation?
Ensure the clamping set and replacement screws match the central cylindrical hole plus one-sided countersink (40°–60°) and that the holder provides correct support for the 3.97 mm thickness to maintain repeatable positioning and cutting accuracy.
