VNMG160412-MK5 WKK10S — indexable turning insert for cast iron | Walter Tools

The VNMG160412-MK5 WKK10S is a negative-geometry, rhombic 35° turning insert engineered for productive machining of cast iron components.

Tiger·tec Silver coated grade WKK10S
Optimised for cast iron (ISO K)
Rhombic 35° insert, 1.2 mm corner radius
Negative 0° geometry with MK5 chipbreaker

High wear resistance for abrasive cast iron cuts

The coated carbide of the WKK10S grade, realised in the Tiger·tec Silver technology, delivers a balanced combination of wear resistance and fracture toughness specifically for cast iron. This makes the insert suited to the short, brittle chip forms typical of grey and nodular cast irons. The applied coating reduces abrasive wear and extends edge life under cyclic loading; the result is predictable tool life and fewer tool changes, supporting a smoother production flow with reduced downtime.

Stable geometry for consistent surface quality

The insert’s rhombic 35° shape and negative 0° rake create a robust cutting edge that tolerates interrupted cuts and variable cross-sections. The 1.2 mm corner radius provides a compromise between strength and surface finish, enabling both light finishing and heavier engagement without premature edge failure. The specified tolerance class M ensures consistent fit in standard toolholders, supporting repeatable set-ups and reduced rework.

Effective chip control and process efficiency

Equipped with the MK5 chipbreaker, this insert promotes controlled chip segmentation and evacuation when machining abrasive cast-iron grades. Controlled chips lower the risk of part damage and speed up post-process cleaning. The insert’s coated carbide substrate assists thermal stability at elevated cutting temperatures, contributing to sustained cutting performance. For workshops seeking improved uptime, the combination of coating, geometry and chip control translates into fewer indexings and steadier cycle times.
