Delivering consistent performance on rostfreier Stahl

The combination of the coated cemented carbide grade WMP20S and the Tiger·tec Silver technology is focused on process stability when machining rostfreier Stahl. The engineered coating increases wear resistance and supports a secure cutting edge under elevated temperatures and adhesive wear conditions typical for these alloys. Paired with the FM4 chipbreaker, the insert promotes controlled chip formation and evacuation, which reduces the risk of built-up edge and helps maintain tool life. For production environments seeking predictable cycle times, this equates to fewer tool changes and steadier component quality.

Geometry tuned for surface finish and repeatability

The rhombic 55° shape and a 0.4 mm corner radius are optimised to balance strength and finish. The geometry delivers reliable engagement in shoulder and light profiling operations, while the modest corner radius helps achieve a consistent surface texture without excess cutting forces. The 7° clearance supports secure edge contact and reduces rubbing on the flank, contributing to repeatable results across batches. These design choices make the insert well suited for shops that prioritise part consistency and minimised rework.

Process productivity through controlled chip flow and edge stability

In industrial turning, predictable chip behaviour and a stable cutting edge translate directly into higher uptime. The FM4 chipbreaker is designed to create compact, manageable chips when cutting rostfreier Stahl, which lowers the risk of chip entanglement and eases machine housekeeping. The coated grade WMP20S supports mid-to-robust cutting conditions, helping to prolong effective tool life and reduce the frequency of indexings. For production planners and toolroom managers this means improved process reliability and a positive effect on overall throughput.

Practical integration and handling on standard toolholders

The insert designation follows established indexable turning conventions, enabling straightforward fitting into compatible toolholders for the DCMT family. Its T3 thickness and the 11-sized profile allow secure clamping and simple indexing to fresh cutting edges when required. As with all indexable solutions, correct seat contact and torque settings are essential to obtain the expected performance; proper clamping ensures even distribution of cutting loads and prolongs edge life. The insert is therefore a pragmatic choice for workshops seeking an efficient balance between performance and handling.
