TNMG160408-MK5 WKK10S — indexable turning insert, triangular 60°, Walter Tools

TNMG160408-MK5 WKK10S is a coated indexable turning insert designed for productive machining of cast iron components

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron (ISO group K)
• Triangle 60° form for secure clamping
• MK5 chipbreaker for stable chip control

Increased process reliability when machining cast iron

The WKK10S grade, as used on this insert, is tuned for abrasive conditions typical of cast iron (ISO K). The combination of a wear-resistant Tiger·tec Silver coating and a carbide substrate produces consistently durable cutting edges, reducing the frequency of tool changes and unplanned stoppages. For production environments seeking predictable tool life, this insert supports a smoother workflow and lower overall tooling cost per part.

Geometry engineered for steady chip control and tool life

The triangular 60° form and the MK5 chipbreaker ensure dependable chip formation during interrupted and continuous cuts. The 0.8 mm corner radius provides a compromise between edge strength and insert accessibility, offering robust resistance to edge chipping while maintaining a fine surface finish. The 0° (negative) rake promotes stable cutting forces on harder cast-iron grades and contributes to repeatable dimensional accuracy in series production.

Coating and grade benefits translated into production advantages

The Tiger·tec Silver coating improves thermal and abrasive resistance, which means that the cutting edge maintains integrity under higher temperatures and abrasive particulate typical for grey and nodular cast irons. This results in longer tool life and fewer indexings per job. The WKK10S carbide grade gives universal toughness for many cast-iron subtypes, allowing reliable performance across different workpiece compositions without constant grade swaps.

Practical notes for integration and handling in the workshop

The insert is supplied in the TNMG160408-MK5 geometry, compatible with standard TNMG toolholders for turning operations. Its tolerance class M and execution G indicate consistent manufacturing precision and stable seating in the tool pocket. When integrating into a production cell, consider the insert’s negative rake and corner radius when selecting feeds and depths of cut to balance productivity with surface requirements. Proper clamping and correct seat condition will leverage the insert’s designed repeatability.

FAQ

Which materials is this insert intended for?
The TNMG160408-MK5 WKK10S insert from Walter Tools is optimised for cast iron (ISO K) applications and is designed to handle abrasive, short-breaking chips typical for those materials.

What advantage does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WKK10S grade increases thermal and abrasive resistance, which extends edge life and reduces tool-change frequency for the insert during series turning operations.

How does the MK5 chipbreaker affect machining?
The MK5 chipbreaker promotes controlled chip formation and evacuation on cast iron, improving process stability and reducing the risk of built-up edge or erratic chip behaviour with this insert.

Is the TNMG160408-MK5 form compatible with standard toolholders?
Yes. The TNMG160408-MK5 geometry is a standard indexable insert form and fits toolholders designed for TNMG inserts, subject to correct seat condition and clamping practice.
