T CCMT120404-FK6 WKK20S indexable insert — FK6 chipbreaker, Tiger·tec Silver by Walter Tools

T CCMT120404-FK6 WKK20S is an indexable turning/boring insert designed for productive machining of cast iron and similar abrasive materials, featuring a rhombic 80° geometry and a 0.4 mm corner radius.

• Tiger·tec Silver coated carbide grade
• Optimised for cast iron machining
• FK6 chipbreaker for reliable chips
• Rhombic 80° geometry, 0.4 mm corner radius

Increased productivity for abrasive cast-iron work

The combination of Tiger·tec Silver coating and the WKK20S grade is engineered to cope with the abrasive nature of cast iron, offering stable cutting performance under typical interrupted or continuous turning. The coated carbide substrate resists abrasive wear and maintains a sharp, stable edge, which reduces the frequency of insert changes and contributes to a steadier process flow. The FK6 chipbreaker is tailored to produce short, controllable chips when machining brittle materials, which simplifies chip evacuation and reduces the risk of re-cutting. This design focus supports a rational improvement in cycle times and productivity without compromising component quality.

Consistent surface finish and dependable tool life

The rhombic 80° geometry with 7° clearance and a 0.4 mm corner radius delivers a reliable contact geometry that balances edge strength with surface integrity. The specified tolerance class M ensures consistent dimensions across lots, aiding predictable setup and repeatable results. For production environments where process stability is paramount, these combined features translate into fewer stoppages for tool changes and more parts produced within tolerance. The coated grade and geometry reduce edge chipping on interrupted cuts, improving surface finish and lowering rework rates — a rational benefit for job shops and OEM subcontractors focused on efficiency.

Practical handling and flexible tooling options

The insert's standard CCMT form and the size designation make it compatible with conventional indexable tool holders for turning and boring, enabling straightforward integration into existing tooling systems. The indexable insert format allows quick rotation to fresh cutting edges, cutting downtime and simplifying inventory management compared with brazed or solid tooling alternatives. The material and chip control characteristics suit workshops producing cast-iron components that require predictable repeatability and straightforward handling. The CCMT120404-FK6 WKK20S by Walter Tools is particularly relevant where controlled chip form and reliable edge life matter most.

FAQ

What materials is this insert intended for?
The CCMT120404-FK6 WKK20S insert is designed primarily for cast iron machining; the WKK20S grade and Tiger·tec Silver coating are adapted to abrasive, chip-breaking behaviour typical of cast materials.

Does the FK6 chipbreaker support interrupted cuts?
Yes, the FK6 chipbreaker is engineered to produce short, manageable chips and to maintain edge stability during the short, breaking chip conditions commonly encountered when turning cast iron.

Is this insert compatible with standard CCMT holders?
The CCMT120404-FK6 WKK20S follows the CCMT form factor and is compatible with standard CCMT indexable tool holders used for turning and boring operations.

What finishing quality can be expected with the 0.4 mm corner radius?
The 0.4 mm corner radius provides a balance between edge strength and surface finish; it supports good component appearance while offering robustness against edge chipping on typical cast-iron components.

Can the insert be reground or reconditioned?
This product is an indexable insert intended for rotation to fresh edges rather than regrinding; the coated substrate and specific geometry are optimised for single-use indexing and replacement.
