BCMT120420L-G55 WKP35G – Indexable milling insert with Tiger·tec Gold coating for steel and cast iron | Walter Tools

The BCMT120420L-G55 WKP35G indexable milling insert is designed for high-productivity milling operations on steel and cast iron, combining a Tiger·tec Gold coating with a G55 chipbreaker for stable chip control.

• Tiger·tec Gold coating for extended tool life
• WKP35G grade optimised for steel and cast iron
• Parallelogram 75° form for secure chip control
• 7° relief with 2 mm corner radius for stability

Consistent productivity through optimised coating and grade

The combination of the Tiger·tec Gold coating and the WKP35G carbide grade delivers a measurable increase in process reliability when machining ISO groups P and K (steel and cast iron). The coating reduces abrasive wear and thermal softening, which translates into longer cutting edge life and fewer tool changes. For production environments this means higher machine uptime and a lower cost per component—an economical advantage that becomes apparent across medium- to high-volume runs. The insert’s ability to maintain a stable cutting edge under the thermal and mechanical loads typical for steel machining supports predictable cycle times and consistent part quality.

Geometry engineered for chip control and machining stability

The parallelogram 75° form combined with the G55 chipbreaker is engineered to produce short, controllable chips on a wide range of steels and cast irons. The geometry promotes secure clamping and directs chips away from the cutting zone, reducing the risk of re-cutting and improving surface finish. The 7° relief angle enhances insert strength at the cutting edge while the 2 mm corner radius increases robustness against edge chipping, making the insert suitable for interrupted cuts and mixed-production shops. These geometric choices reduce unplanned downtime and help to maintain repeatable tolerances in demanding operations.

Practical integration and reliable process behaviour

Designed as a direct fit for standard milling toolholders, the insert offers straightforward integration into existing toolsets and machining programmes. The G55 chip control and Tiger·tec Gold technology support stable machining across varying workpiece materials classified under ISO P and K, reducing setup iterations and trial cuts. The insert’s tolerance class M ensures consistent seating and repeatable positioning in the cutter body, contributing to reproducible component geometry. For operations seeking to improve throughput while safeguarding surface integrity, this insert combines material versatility with process security.
