High abrasion resistance and longer tool life for cast iron production

The coated carbide grade WKK20S, part of the Tiger·tec Silver series, is formulated specifically for the demands of machining cast iron. The combination of a hard, wear-resistant coating and a substrate tuned for the abrasive nature of cast materials supports stable chip formation and extended edge life. This results in fewer tool changes and improved uptime on the shop floor, particularly when short, breaking chips are to be expected with grey and nodular cast irons. The specification targets a balance between toughness and wear resistance so that the cutting edge remains consistent under industrial cycle times.

Robust geometry for interrupted cuts and repeatable results

The triangular 60° plate form provides three indexable cutting edges, enabling quick re-indexing and efficient stock usage. The 0° negative rake increases edge strength for interrupted or heavy engagement cutting, while the 1.6 mm corner radius delivers enhanced edge support for stable feeds and improved surface finish where modest corner rounding is acceptable. The insert’s 16 mm inscribed circle dimension ensures compatibility with a wide range of toolholders designed for this common size class. Tolerance class M supports consistent seating and repeatable location in compatible toolholders, helping to reduce variability between re-indexes.

Controlled chip forming and process reliability in turning operations

The integrated MK5 chipbreaker is designed to assist with chip control when machining abrasive cast iron grades, reducing the risk of long, entangling chips and easing handling in automatic production lines. The coated carbide construction and chipbreaker geometry contribute to predictable cutting forces and improved thermal resistance, which together support higher productivity and less downtime. For technical assessment or specific cutting data, Metav Werkzeuge can provide application guidance and machining parameters tailored to the workpiece and machine tool; this helps to translate the insert’s technical profile into measurable process improvements on the shop floor.

FAQ

What materials is this insert intended for?
This insert is optimised for cast iron machining; the WKK20S grade and chipbreaker are tailored to the abrasive behaviour and short-chip characteristics of cast materials.

Can the TNMG160416-MK5 WKK20S be used for interrupted cuts?
Yes, the 0° negative rake and the 1.6 mm corner radius provide additional edge strength suitable for interrupted cutting conditions.

How does the MK5 chipbreaker affect chip control?
The MK5 chipbreaker promotes controlled, short chips when turning cast iron, lowering the likelihood of long, hazardous chip formation and supporting automated chip handling.

Is this insert suitable for stainless steel or high-alloy steels?
The WKK20S grade is designed for cast iron; for stainless steel or highly alloyed steels, a grade specifically formulated for those materials is recommended.

What does tolerance class M indicate for toolholders?
Tolerance class M denotes a medium tolerance level for insert dimensions and seating, which helps ensure consistent fit and repeatable positioning in compatible toolholders.
