LPMT150612R-D57 WKP25S — Rectangular milling insert, Tiger·tec Silver, for Stahl and Gusseisen | Walter Tools

The LPMT150612R-D57 WKP25S is a coated carbide rectangular milling insert designed for robust finishing and semi-finishing operations on Stahl and Gusseisen, combining wear resistance with secure cutting-edge stability.

• Tiger·tec Silver coating technology
• Coated carbide for stable performance
• Rectangular geometry, 1.2 mm corner radius
• Suitable for Stahl and Gusseisen machining

Consistent productivity through reliable coating and grade

The Tiger·tec Silver grade delivers a coated carbide substrate tailored to sustained cutting under typical steel and cast-iron conditions. By combining a modern coating stack with a grade focused on wear resistance, the insert reduces flank wear and maintains a stable cutting edge over longer cycles. This results in predictable tool-life windows and fewer tool changes, which supports higher machine uptime and a more efficient production flow. The WKP25S grade is particularly effective where a balance between abrasion resistance and toughness is required.

Geometry designed for secure chip control and surface quality

A rectangular plate form with a 1.2 mm corner radius and an 11° free angle offers a controlled engagement with the workpiece, favouring improved surface finish and dimensional stability during finishing passes. The dedicated D57 chipbreaker geometry assists in consistent chip formation when machining both short and intermittently breaking chips typical of Gusseisen, while also handling continuous chips encountered in Stahl. For process planners this means fewer interruptions, predictable thermal load at the cutting edge and a reduced risk of poor surface integrity.

Practical application and process support for workshop integration

The insert’s specification makes it suitable for a broad range of general-purpose milling fixtures and toolholders that accept the LPMT form. With a tolerance class of M and the compact plate size, the component integrates easily into standard tool assemblies and indexable tool systems. If specific cutting parameters are required for a component, Metav Werkzeuge’s technical consultants can provide recommended feeds and speeds based on the workpiece material and machine capability. For complex or critical components, targeted advice helps to secure the expected cycle time and component quality.
