SNMG190616-MK5 WKK20S — Indexable turning insert, Tiger·tec Silver, Walter Tools

SNMG190616-MK5 WKK20S is an indexable turning insert designed for efficient machining of cast iron with a 0° negative rake and MK5 chipbreaker

• Tiger·tec Silver coating
• Optimised for cast iron machining
• Square 90° geometry for stable cuts
• MK5 chipbreaker for reliable chip control

Boosted productivity for cast iron turning

The WKK20S grade of the Tiger·tec Silver series is a coated carbide solution optimised for abrasive wear and the short, breaking chips typical of cast iron. This composition translates into longer tool life and fewer insert changes during batch production, supporting predictable cycle times and reduced process downtime. The combination of coating technology and grade selection focuses on maintaining cutting performance under the thermal and mechanical stresses common when machining grey and nodular cast irons, so production runs remain efficient and consistent.

Stable cutting and controlled chip formation

A square 90° geometry provides rigidity and a secure seating in the toolholder, while the MK5 chipbreaker promotes orderly chip evacuation and reduced re-cutting of chips. The 0° negative rake further enhances edge stability for interrupted cuts and heavy engagement typical in roughing operations on cast components. Together these characteristics improve surface quality and reduce the risk of edge chipping, resulting in fewer rejects and more predictable finishing passes for downstream processes.

Practical compatibility and economical operation

The insert follows the SNMG form factor and is identified as SNMG190616-MK5 WKK20S, making it compatible with standard SNMG toolholders. The 1.6 mm corner radius balances edge strength and accessible finishing capability, while the thickness code (06) and tolerance class M deliver repeatable fit and performance across tool changes. For workshops seeking a dependable balance between economics and process security, this insert supports extended tool life and reliable results in cast-iron production environments.

FAQ

Which materials is this insert intended for?
This insert is optimised for machining cast iron; the WKK20S grade and Tiger·tec Silver coating are tuned to resist abrasive wear and to manage the short, breaking chips common in cast materials.

Does this insert fit standard SNMG toolholders?
Yes — the SNMG190616 form factor denotes compatibility with toolholders designed for SNMG inserts; the supplied designation SNMG190616-MK5 WKK20S identifies the exact geometry and chipbreaker.

What advantage does the MK5 chipbreaker offer?
The MK5 chipbreaker promotes controlled chip formation and evacuation, reducing the chance of tangled chips and improving surface consistency during continuous and interrupted cut conditions.

How does the Tiger·tec Silver coating affect tool life?
The Tiger·tec Silver coating on the WKK20S grade reduces abrasive wear and enhances thermal stability, supporting longer service life and more consistent performance across production batches.

Is the insert suitable for interrupted cuts or heavy roughing?
The square 90° geometry combined with a 0° negative rake and a 1.6 mm corner radius provides a robust cutting edge suitable for interrupted cuts and heavy engagement in cast-iron turning.
