LNMU160812-F57T WSM35G rectangular milling insert by Walter Tools — Tiger·tec Gold for hard-to-machine alloys

LNMU160812-F57T WSM35G is a rectangular indexable milling insert designed for heavy-duty operations in heat-resistant alloys and rostfreier Stahl, delivering robust edge life and stable chip formation

• Tiger·tec Gold coated carbide grade WSM35G
• Optimised chipformer F57T for stable chips
• 0° negative rake for heavy roughing
• Rectangular 16 mm insert with 1.2 mm corner

Consistent performance for hard-to-machine materials

The coated cemented-carbide grade WSM35G from the Tiger·tec Gold family is engineered for demanding milling of rostfreier Stahl and nickel-based superalloys. Its coating and substrate combination promote stable chip formation and resist thermal loading, so machining cycles run with fewer interruptions. The insert geometry, paired with an F57T chipformer, reduces the risk of built-up edge and supports a predictable cutting process, which in turn lowers tool change frequency and increases overall productivity.

Secure edge stability and economy in production

A 0° (negative) free angle increases the effective support behind the cutting edge, improving robustness during interrupted cuts and heavy engagement. This design choice favours durability over minimal cutting forces, making the insert particularly suitable for roughing contours and shoulder milling where edge security matters. The economic advantage arises from prolonged tool life and fewer scrap parts, contributing directly to a lower cost per component in continuous production.

Geometry and handling that support process reliability

The rectangular form with a 1.2 mm corner radius provides a compromise between edge strength and achievable profile detail. The 16 mm designation denotes the insert size for stable clamping in standard milling cutters that accept LNMU-type inserts. Thanks to the integrated F57T chip control, chips are guided away from the cutting zone, improving surface integrity and reducing heat concentration at the cutting edge—factors that extend service intervals and simplify process planning.

Integration into the machining workflow and selection guidance

When selecting tooling, pair this insert with cutters and feeds geared to the intended material group: lower cutting speeds for rostfreier Stahl and adjusted feeds for superalloys to manage heat. The insert’s WSM35G grade provides a broad material window; however, matching holder rigidity and coolant strategy will maximise the benefits of the grade. For customers seeking reproducible results, this combination supports a steady process window and reduces variance between batches.

FAQ

What materials is this insert suitable for? This rectangular milling insert by Walter Tools is specified for material groups S and M, meaning it is suitable for superalloys and rostfreier Stahl, as indicated by the WSM35G grade.

How does the F57T chipformer influence machining? The F57T chipbreaker promotes controlled chip formation and evacuation; with the WSM35G grade and appropriate cutting parameters it helps maintain surface quality and reduces heat buildup at the cutting edge.

Is the 0° free angle suitable for interrupted cuts? Yes — the 0° (negative) free angle increases edge support and makes the insert robust under interrupted or heavy-engagement milling typical in roughing operations.

What does the designation LNMU160812-F57T indicate? The designation describes the insert geometry (rectangular LNMU), the size (16), the thickness and corner details (0812), and the integrated chipformer (F57T) used in this Walter Tools insert.

Which series and coating technology does this grade belong to? The insert belongs to the Tiger·tec Gold series; the WSM35G grade is a coated cemented-carbide variety optimised for heat resistance and stable cutting edges.
