DNMA110404-RK5 WKK10S Turning Insert — Tiger·tec Silver for Cast Iron (Walter Tools)

A DNMA110404-RK5 WKK10S turning insert engineered for productive cast iron machining, combining Tiger·tec Silver technology and an RK5 chipbreaker for controlled chips.

• Tiger·tec Silver grade for high wear resistance
• Optimised RK5 chipbreaker for clean chips
• Rhombic 55° shape for versatile turning
• Corner radius 0.4 mm for stable cutting

Higher throughput through wear-resistant grade and chip control

The combination of the Tiger·tec Silver technology and the WKK10S carbide grade is designed to extend tool life under abrasive conditions typical for cast iron. The coating reduces flank and crater wear, which allows longer uninterrupted production cycles and fewer insert changes. The RK5 chipbreaker shapes short, predictable chips to prevent entanglement and reduce downtime; in practical terms this means higher material removal rates and improved process stability, which together lower unit machining costs and increase overall workshop efficiency.

Geometry that stabilises cutting and improves surface finish

The rhombic 55° plate form and negative 0° rake angle give mechanical robustness for heavy or interrupted cuts, while the 0.4 mm corner radius balances edge strength with surface quality. Negative rake geometries resist chipping under shock loads, so dimensional accuracy and repeatability are maintained lap after lap. For users unfamiliar with the terms: a corner radius supports the cutting edge against fracture, and a negative rake builds durability — both contribute to consistent part quality and fewer rejects.

Practical selection and application guidance for cast iron work

Specified for ISO group K (cast iron), the insert is suitable where short, brittle chips and abrasive wear are expected. The plate designation and form make it compatible with standard DNMA-style toolholders, enabling straightforward integration into existing turning setups. Choose appropriate feeds and speeds for the machine rigidity and workpiece grade to exploit the WKK10S advantages: improved tool life and consistent surface finish. For volume production or challenging cast-iron alloys, this insert supports stable cycles and predictable tool-change intervals, helping to plan maintenance windows and throughput.

FAQ

Which materials is this insert intended for?
The DNMA110404-RK5 WKK10S turning insert is optimised for cast iron (ISO group K) and is designed to cope with the abrasive and short-chip behaviour of such materials.

What is special about the WKK10S grade?
WKK10S, in the Tiger·tec Silver family, offers enhanced wear resistance and thermal stability for cast-iron turning, which helps to extend tool life and maintain consistent cutting performance.

How does the RK5 chipbreaker affect machining?
The RK5 chipbreaker produces short, controlled chips that reduce entanglement risk and improve process reliability when using the DNMA110404-RK5 WKK10S insert.

Can the insert be used in standard DNMA toolholders?
Yes, the DNMA110404-RK5 form matches common DNMA-style holders; verify seat and clamping compatibility before mounting.

What cutting conditions are recommended for best results?
Moderate to high cutting speeds with stable feed rates and proper coolant strategies are typically effective for cast-iron applications with this grade; adjust parameters based on machine rigidity and workpiece specifics.
