TCMT16T304-MK4 WKK20S — Drilling/boring & turning indexable insert, triangle 60°, for cast iron — Walter Tools

The TCMT16T304-MK4 WKK20S is a coated carbide indexable insert engineered for drilling, boring and turning operations on cast iron, offering a balance of durability and reliable chip control.

Tiger·tec Silver coating for enhanced wear resistance
Designed for machining cast iron (ISO group K)
Triangle 60° form with 0.4 mm corner radius
MK4 chipbreaker for controlled chip formation

Consistent chip control for abrasive cast‑iron work

The combination of the MK4 chipbreaker and the WKK20S grade gives a predictable chip flow when machining cast iron, addressing the typical short, brittle chips of these materials. In practice, this means fewer interruptions from chip jamming and a steadier machining cadence. The insert’s chipformer is optimised for abrasive wear, which helps to maintain cutting-edge integrity over longer tool life and reduces unplanned stops in production.

Geometry tuned for repeatable surface quality

Featuring a triangle 60° shape with a corner radius of 0.4 mm and a 7° clearance, the insert provides a stable cutting geometry that supports dimensional consistency and reliable surface finish. The acute form suits both radial and axial engagement conditions commonly found in drilling and turning operations. Such geometry helps to reduce vibration and ensures repeatable results when inserted into standard toolholders.

Tiger·tec Silver coating extends productive lifetime

The insert’s affiliation with the Tiger·tec Silver series indicates a coated carbide technology focused on wear resistance and broad applicability across cast‑iron grades. The coating reduces flank wear under the high abrasion typical of cast materials, extending the period between index changes and contributing to lower overall tooling consumption. As a consequence, process reliability improves and the frequency of machine downtime for insert replacement is reduced.

Simple specification for easy integration into production

The insert is coded as TCMT16T304‑MK4 WKK20S, with a plate size of 16 mm and plate thickness T3, enabling straightforward selection for holders specified to this ISO designation. The clear labelling and standard geometry support quick inventory management and predictable interchangeability across machines. For production planning, this insert is suitable wherever cast‑iron components require efficient, stable machining with controlled chip formation.

FAQ

What materials is this insert intended for?
The TCMT16T304‑MK4 WKK20S is designed for cast iron machining (ISO group K), with the WKK20S grade optimised for abrasive cast materials.

How does the Tiger·tec Silver coating benefit performance?
The Tiger·tec Silver coating on this Walter Tools insert reduces flank wear and extends productive life under the abrasive conditions typical of cast‑iron turning and drilling.

Which chip behaviour can be expected with the MK4 chipbreaker?
The MK4 chipbreaker promotes controlled, short chip formation suited to cast iron, reducing the risk of entanglement and improving process stability.

Is the insert compatible with standard TCMT toolholders?
Yes, the ISO designation TCMT16T304‑MK4 corresponds to standard TCMT holders; the triangle 60° form and size ensure straightforward interchangeability.

What dimensional features support consistent surface finish?
The combination of 0.4 mm corner radius and 7° clearance provides a stable cutting geometry that helps achieve repeatable surface quality and dimensional control.
