DCMT11T304-RK4 WKK10S indexable turning insert, Rhombus 55° for cast iron — Walter Tools

A DCMT11T304-RK4 WKK10S indexable turning insert designed for productive machining of cast iron, combining a Rhombus 55° geometry with a chipbreaker optimised for brittle materials

• Tiger·tec Silver coated grade WKK10S
• RK4 chipbreaker for consistent chip control
• Rhombus 55° geometry for flexible turning
• 0.4 mm corner radius for fine surface finish

Stable chip control for continuous production

The RK4 chipbreaker is engineered for the short, brittle chips typical of cast iron, giving stable evacuation and reduced risk of edge damage. This leads to fewer interruptions and a steadier process window, which is a direct advantage in high-volume turning operations. The insert’s rhombus 55° geometry enables a range of approach angles, making the component suitable for both finishing and light to medium roughing where consistent chip formation and tool life are priorities.

Coating and grade that prolong cutting edge life

The combination of the WKK10S grade with Tiger·tec Silver coating provides a wear-resistant facing optimised for abrasive cast-iron workpieces. The grade is a coated carbide, tailored for abrasive wear resistance and reliable performance in interrupted cuts; this reduces flank wear and maintains dimensional accuracy over longer tool life. Explaining the technical advantage: the coating reduces friction and thermal load at the cutting zone, while the substrate provides toughness to withstand the frequent micro‑impacts that occur when machining grey and nodular cast iron.

Geometry and dimensions that support precision and flexibility

The insert’s 0.4 mm corner radius and 7° clearance balance surface quality and strength at the edge; the small radius improves finish while the clearance angle helps avoid rubbing on the workpiece. The 11 mm size and T3 thickness suit common toolholder systems accepting DCMT-style inserts, and the tolerance class M ensures repeatable seating in the pocket. Taken together, these parameters translate into a predictable cutting behaviour and simpler process setup, particularly when paired with toolholders and feeds optimised for cast-iron turning.

FAQ

What materials is this insert intended for?
The DCMT11T304-RK4 WKK10S insert is designed primarily for cast iron machining; the WKK10S grade and Tiger·tec Silver technology target the abrasive wear and short, breaking chips of cast-iron workpieces.

How does the RK4 chipbreaker affect machining?
The RK4 chipbreaker promotes stable chip formation and controlled evacuation, which reduces the risk of built-up edge and contributes to consistent surface quality when turning cast iron with the DCMT11T304-RK4 WKK10S insert.

Is the geometry suitable for finishing operations?
Yes — the Rhombus 55° shape combined with a 0.4 mm corner radius provides a good balance between edge strength and fine surface finish for finishing and light to medium roughing passes.

Can the insert be used in interrupted cuts?
The WKK10S coated carbide grade and robust substrate make the insert tolerant of interrupted cuts commonly encountered in cast-iron turning, offering improved resistance to micro‑impacts.

Which toolholders are compatible with this insert?
The DCMT-style seating fits standard toolholders for 55° rhombus inserts; using holders specified for DCMT11 sizes ensures proper clamping and repeatable positioning of the WKK10S insert.
