WNMG080404-MK5 WKK10S turning insert — Trigon 80°, Tiger·tec Silver (Walter Tools)

A WNMG080404-MK5 WKK10S turning indexable insert designed for high‑productivity machining of cast iron, delivering controlled chips and extended tool life

• Tiger·tec Silver coated for high wear resistance
• Trigon 80° form for stable cutting
• MK5 chipbreaker for controlled chip formation
• 0.4 mm corner radius for fine surface quality

Increased productivity through tailored carbide and coating

The WKK10S grade, part of the Tiger·tec Silver series, combines a coated carbide substrate with a coating engineered for abrasive cast‑iron conditions. This composition reduces flank wear and extends edge life, which translates directly into longer tool cycles and fewer insert changes. As a result, set‑ups for serial turning run more continuously and machining costs per component fall, improving overall process economics. The insert’s proven wear behaviour supports predictable tool change intervals and stable cycle times.

Consistent surface results from robust geometry and chip control

The Trigon 80° shape with a 0.4 mm corner radius and MK5 chipbreaker provides a balance between edge strength and surface finish. The negative 0° relief gives a sturdy cutting edge that resists chipping during interrupted cuts common in cast‑iron work, while the MK5 chipformer shapes short, easily evacuable chips. This combination reduces the risk of built‑up edge and maintains dimensional consistency across batches. The geometry is therefore ideal where repeatable surface quality and easy chip evacuation are priorities.

Process reliability and application focus for cast‑iron machining

Engineered for the abrasive and brittle behaviour of cast iron, the insert supports stable chip formation and predictable wear patterns, which are essential for continuous production. The insert’s format and grade make it particularly effective for roughing and medium finishing of grey and nodular cast irons where short chips and edge robustness are required. With clear specifications like the Trigon form and MK5 chipbreaker, tool planners can match insert selection to cycle requirements and maximise machine uptime.

FAQ

What materials is this insert intended for?
The WNMG080404-MK5 WKK10S insert is designed primarily for cast iron machining; the WKK10S grade and Tiger·tec Silver coating are optimised for abrasive, break‑forming chips typical of cast materials.

How does the MK5 chipbreaker affect machining?
The MK5 chipbreaker produces short, controlled chips that ease evacuation and reduce re‑cutting, helping the insert maintain consistent cutting conditions when turning cast iron with the WNMG080404-MK5 WKK10S.

What advantage does the Trigon 80° shape offer?
The Trigon 80° geometry gives a stable cutting edge and good penetration for bulk material removal, while the 0.4 mm corner radius helps achieve improved surface quality during medium finishing passes.

Is the WKK10S grade suitable for finishing operations?
Yes; while optimised for wear resistance in abrasive cast‑iron conditions, the WKK10S grade and robust geometry of the WNMG080404-MK5 also support medium finishing where controlled chip formation and surface quality are required.

Which product code should be referenced when ordering or specifying tooling?
Use the SKU WNMG080404-MK5-WKK10S-WALTER or the ISO designation WNMG080404-MK5 WKK10S to ensure the correct Tiger·tec Silver grade and MK5 chipbreaker are supplied.
