CNMA160616-RK7 WKK10S — Indexable turning insert with Tiger·tec Silver for cast iron The CNMA160616-RK7 WKK10S is a negative-rake, rhombic 80° turning insert optimised for machining cast iron in production and workshop environments Tiger·tec Silver coating for high wear resistance Designed for cast iron (ISO group K) machining Rhombic 80° shape for versatile turning 1.6 mm corner radius and 0° (negative) relief angle Improved process stability and longer tool life The Tiger·tec Silver coating combined with the WKK10S grade offers a balance of abrasion resistance and toughness tailored for abrasive cast-iron materials. This coating technology enhances flank and crater wear behaviour, so the insert maintains cutting geometry for longer periods under cyclic loads. The integrated RK7 chipbreaker controls brittle, short chips typically produced when turning grey and nodular cast iron, reducing the risk of built-up edge and interrupted cutting. As a result, cycle times are stabilised and tool-change intervals are extended, supporting predictable production throughput and lower tooling costs per part. Secure clamping and reliable cutting performance The Rhombic 80° geometry with a 1.6 mm corner radius provides a favourable combination of edge strength and accessibility for a wide range of turning operations. The 0° (negative) relief angle increases insert robustness in heavy‑cut or interrupted machining, improving resistance to impact and edge chipping. The insert’s nominal size and thickness ensure compatibility with standard toolholders designed for this insert family, while the tolerance class M supports repeatable seating and concentricity. Together these geometric properties translate into fewer rework cycles and more consistent dimensional results on cast-iron components. Practical benefits for production and workshop use Engineers and machinists benefit from the insert’s focus on cast-iron applications: predictable chip formation, elevated wear resistance thanks to coated carbide, and simplified process setting. The chipbreaker design reduces manual chip handling and assists coolant penetration at the cutting edge, contributing to improved surface finish and reduced cycle interruptions. For users seeking process reliability, this insert represents a targeted solution where material abrasiveness and short, breaking chips are dominant concerns.

Why indexable inserts are indispensable in modern machining
Indexable inserts, also known as cutting inserts or indexable cutting inserts, are standardised, replaceable cutting elements that mount on tool holders such as turning bits, milling cutters or drills. Made from wear-resistant materials like carbide, cermet, ceramic or other superhard grades, they carry the actual cutting edge and allow a worn corner to be rotated or flipped instead of replacing or regrinding the entire tool body.
How these inserts work and when to choose them
In everyday workshop and production settings, indexable inserts perform the direct material removal on the workpiece. Standard inserts for tool systems without internal coolant typically feature closed faces or a single central fixing hole, with heat evacuation handled by external machine nozzles. Inserts designed for systems with internal coolant are engineered to support coolant flow: they include calculated chipbreaker geometries that guide an internal coolant jet under the chip or, in specialised designs, contain sintered microchannels to direct coolant right to the cutting edge. Such coolant-compatible inserts are essential for machining heat-resistant alloys, heavy cutting operations and deep internal machining, where thermal load and chip control are critical.
Tangible benefits for production and workshop efficiency
Choosing the right indexable inserts delivers measurable operational advantages:
- Reduced downtime: faster changeover because a worn insert is simply indexed rather than the whole tool being replaced.
- Extended cutting-edge life: targeted coolant application and optimised chipbreaker design lower thermal stress and improve tool life.
- Consistent part quality: predictable cutting-edge geometry from standardised inserts maintains tolerances across batches.
- Versatility: availability in carbide, cermet, ceramic and superhard grades permits selection according to workpiece material and cutting conditions.
- Lower tooling costs over time: fewer full-tool replacements and less regrinding required.

FAQ
What materials are indexable inserts available in?
Indexable inserts are available in wear-resistant grades such as carbide, cermet, ceramic and other superhard materials, selected according to the workpiece material and cutting conditions.
When should I choose inserts with internal coolant support?
Choose inserts designed for internal coolant when machining heat-resistant alloys, performing heavy cuts or working in deep internal features, because the coolant reduces thermal load at the cutting edge and actively improves chip breakage.
How do chipbreaker geometries affect performance?
Chipbreaker geometries on indexable inserts guide the chip flow and, when matched to an internal coolant jet, direct the coolant under the chip to control temperature and facilitate reliable chip formation, which extends edge life and stabilises machining.
Can standard inserts be used with external coolant only?
Yes; standard inserts for tool systems without internal coolant typically have closed faces or a central fixing hole and rely on external machine nozzles for heat evacuation, which is sufficient for many routine, accessible cuts.
