DNMA150612-RK5 WKK10S — Indexable turning insert, Rhombic 55°, RK5, Walter Tools

The DNMA150612-RK5 WKK10S is an indexable turning insert optimised for machining cast iron, combining a coated carbide grade with a chipbreaker designed for short, brittle chips.

• Tiger·tec Silver coating for high abrasive resistance
• Optimised for cast iron (ISO group K)
• Rhombic 55° geometry with 1.2 mm corner radius
• RK5 chipbreaker for controlled chip formation

Consistent performance for abrasive cast iron turning

The insert from the Tiger·tec Silver series delivers a clear advantage when working with abrasive cast iron: the WKK10S grade is a coated carbide specifically tuned for the short, breaking chips and high abrasion typical of these materials. This translates into a longer effective cutting edge and fewer tool changes, which improves machine uptime and reduces process interruptions. The coating helps to limit flank wear under abrasive conditions, so the result is a more predictable tool life and stable cycle times on serial production. Where high abrasive resistance is required, a coated grade like this provides both economy and operational reliability.

Reliable chip control and improved surface quality

Chip control has a direct effect on safety, surface finish and cycle consistency. The engineered RK5 chipbreaker promotes small, easily evacuable chips when turning cast iron, reducing the risk of entanglement and improving operator safety. Coupled with the Rhombic 55° geometry, the insert enables versatile turning from semi-finishing to light finishing passes. The 1.2 mm corner radius increases edge robustness, helping to maintain a steady contact geometry and consistent surface quality across the part. These features together mean fewer rejected parts and a lower rework quota in everyday production.

Process security and economical productivity

A neutral/negative rake geometry (0° negative) contributes to edge strength during interrupted cuts and heavy engagement, offering improved resistance to chipping in demanding operations. The insert is manufactured to tolerance class M, supporting repeatable seating and accurate indexing in standard toolholders. As part of the Walter Tools Tiger·tec Silver family, this specification aims to balance wear resistance and toughness, supporting stable machining strategies and predictable tool-change intervals. For workshops targeting higher throughput with minimal process variation, this insert supports an efficient and secure production setup.

FAQ

What materials is the insert suited for?
The DNMA150612-RK5 WKK10S is designed for machining cast iron (ISO group K) and matches the abrasive and short-chip characteristics of these materials.

What advantage does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WKK10S grade increases resistance to abrasive wear, which helps to extend tool life and maintain consistent cutting performance on abrasive cast iron.

How does the RK5 chipbreaker affect machining?
The RK5 chipbreaker promotes short, controlled chips that evacuate cleanly, improving surface finish and reducing chip-related interruptions during turning.

Why choose a Rhombic 55° geometry for turning?
A Rhombic 55° insert offers versatility across semi-finishing and finishing operations, balancing cutting edge exposure and strength for reliable surface quality.

What role does the 1.2 mm corner radius play?
The 1.2 mm corner radius increases edge robustness, reducing the likelihood of premature chipping and supporting steady contact conditions for a consistent finish.
