TCMT16T308-RK4 WKK10S Triangle 60° Turning Insert, RK4 Chipbreaker – Walter Tools

The TCMT16T308-RK4 WKK10S is a triangular 60° turning/boring insert designed for productive cast-iron machining with a Tiger·tec Silver coated carbide grade.

• Tiger·tec Silver coating for wear resistance
• WKK10S grade optimised for cast iron
• RK4 chipbreaker for stable chip control
• Triangle 60° insert with 0.8 mm radius

Greater throughput through optimised wear resistance and chip control

The coated carbide grade WKK10S, developed within the Tiger·tec Silver family, is specifically balanced for the abrasive wear and frequently breaking chips encountered in cast-iron machining. The combination of a wear-resistant coating and a dedicated RK4 chipbreaker reduces edge degradation and limits unexpected downtime, delivering noticeable improvements in process reliability and tool life. Explaining the technical effect: the coating lowers friction and thermal stress at the cutting edge, while the RK4 geometry promotes short, controllable chiplets that evacuate cleanly from the cut—this reduces built-up edge and supports repeatable performance in series production.

Consistent surface quality and tool life from precise insert geometry

The insert’s triangle 60° geometry and a 0.8 mm corner radius provide a balanced contact zone between insert and workpiece, helping to maintain dimensional stability and surface finish during turning. A 7° free rake contributes to controlled cutting forces and predictable wear patterns, making the insert suitable for both stabilised finishing and economical material removal strategies on cast iron. With a size 16 and T3 thickness, nominal rigidity supports higher feed rates without compromising part tolerances; the tolerance class M ensures interchangeability and repeatable clamping accuracy in standard toolholders.

Production benefits: consistent chips, lower rework and straightforward tool rotation

In a production setting the insert’s features translate into tangible operational advantages. The RK4 chipbreaker fosters stable chip formation, which reduces machine downtime caused by clogged chip paths and improves operator safety. The coated grade’s resistance to abrasive wear decreases the frequency of index changes, while the triangular format yields three cutting edges per insert, aiding economy. The insert is engineered for cast-iron applications, promoting fewer rejects and reduced rework. For procurement and process planning, reliance on established brand standards like Walter Tools contributes to predictable supply and consistent batch quality across production runs.

FAQ

Which workpiece materials is this insert suitable for?
The TCMT16T308-RK4 WKK10S insert is optimised for cast iron work; the WKK10S grade and Tiger·tec Silver coating specifically address the abrasive nature and chip behaviour of cast-iron alloys.

What benefit does the RK4 chipbreaker provide?
The RK4 chipbreaker produces short, controllable chips that evacuate reliably, reducing chip entanglement and improving machining consistency when turning cast iron with this insert.

Is this insert suitable for finishing as well as roughing operations?
The insert’s triangle 60° geometry and 0.8 mm corner radius offer a compromise between cutting edge robustness and surface quality, making it suitable for stabilised finishing and economical roughing in cast-iron turning.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating reduces friction and thermal load at the cutting edge, which lowers abrasive wear and helps maintain cutting-edge integrity over longer cycles on abrasive cast-iron materials.

What are the key dimensional details to check for holder compatibility?
Verify the size 16, triangle 60° geometry, T3 thickness and tolerance class M against the intended toolholder; these dimensions determine correct seating and repeatable clamping for the insert.
