SNMG120416-MK5 WKK10S – Indexable turning insert, Tiger‑tec Silver (Walter Tools)

The SNMG120416‑MK5 WKK10S is a square 90° indexable insert designed for productive turning of cast iron, pairing a coated carbide grade with an MK5 chipbreaker for consistent short chips and abrasion resistance.

• Tiger‑tec Silver coating for abrasion resistance
• Optimised MK5 chipbreaker for short chips
• Square 90° insert with 1.6 mm corner radius
• Designed for cast iron machining

Consistent wear resistance for longer tool life

The use of the Tiger‑tec Silver coating together with the WKK10S grade offers a balance of abrasion resistance and toughness tailored to abrasive cast iron applications. Coated carbide technology means the cutting edge is protected by a thin, wear‑resistant layer that reduces flank wear and extends useful life, which translates into fewer tool changes and steadier cycle times. For production environments this leads to measurable improvements in uptime and a lower cost per machined component.

Predictable chip control and improved process stability

An MK5 chipbreaker engineered for short, broken chips reduces the risk of entanglement and simplifies material evacuation. Combined with the insert’s square 90° geometry and 1.6 mm corner radius, the result is improved cutting force distribution and repeatable edge engagement. This configuration supports stable machining parameters, allowing for higher material removal rates in many turning operations while maintaining consistent surface quality on cast iron workpieces.

Robust geometry for demanding cutting conditions

The negative relief angle of 0° and the medium tolerance class contribute to a sturdy edge that resists shock and thermal variations typical when machining cast iron. The insert’s design supports interrupted cuts and heavy‑duty turning where chip formation is abrupt and abrasive wear is dominant. Choosing this grade and geometry therefore reduces the frequency of unexpected edge failures and helps maintain process predictability on the shop floor.

Easy integration into production workflows

The insert’s standard SNMG form and the familiar clamping interfaces make it simple to adopt within established toolholding systems. The combination of coated carbide and a dedicated chipbreaker reduces the need for constant parameter adjustments; operators gain a straightforward setup with reproducible results. For workshops seeking to raise productivity without extensive process requalification, this insert presents a practical step towards greater machining efficiency.
