Boring/drilling and turning indexable insert CCMT09T302-FM4 WMP20S — Tiger·tec Silver coating, 0.2 mm radius, Walter Tools

The CCMT09T302-FM4 WMP20S is a rhombic 80° indexable insert for combined boring, drilling and turning operations, optimised for machining stainless steel under medium to robust cutting conditions.

• Tiger·tec Silver coating for increased tool life
• Optimised for stainless steel machining
• FM4 chipbreaker for secure chip control
• 0.2 mm corner radius for precise finishing

Consistent productivity through a robust coating and grade

The combination of the Tiger·tec Silver coating with the WMP20S grade provides a balance of wear resistance and edge stability, specifically developed for stainless steel. This translates into fewer unscheduled index changes and a predictable machining rhythm; a coated cemented-carbide substrate resists adhesion and thermal softening, which is crucial when machining heat-prone alloys. The result is a measurable reduction in downtime and more consistent part tolerances, especially on medium to heavy cutting tasks.

Secure chip control and repeatable surface quality

The FM4 chipbreaker delivers controlled chip formation even in demanding stainless steel applications, while the 0.2 mm corner radius supports fine finishing without compromising edge strength. The rhombic 80° geometry and a 7° clearance angle form a stable cutting edge that reduces vibration and improves surface finish on turned and bored faces. Explaining the terms: a chipbreaker guides and breaks the swarf into manageable lengths; a small corner radius balances finish quality and robustness, making the insert suitable for finishing passes or light roughing where surface integrity matters.

Clear application guidance and process advantages

Designed for versatile use in turning and boring tool holders, the indexable insert concept keeps tool inventory lean and reduces regrind cycles. The CCMT09T302-FM4 WMP20S performs reliably in serial production due to the stable chip control and consistent edge life of the WMP20S grade. For process planning, select feeds and speeds in line with stainless steel recommendations, monitor cutting temperature, and use the FM4 chip control for interrupted cuts. The practical benefit: improved throughput and predictable tool-change intervals, supporting a cost-efficient production flow without compromising component quality.

FAQ

What materials is this insert suitable for? The CCMT09T302-FM4 WMP20S is specified for stainless steel and is engineered to handle the toughness and heat sensitivity typical of that material group.

What does the FM4 chipbreaker do? The FM4 chipbreaker on this insert controls swarf geometry to prevent long, stringy chips and to promote safe evacuation and consistent cutting forces during machining.

Can the insert be used for both turning and boring operations? Yes, the rhombic 80° form and the CCMT designation make this insert compatible with appropriate turning and boring tool holders for both operations.

How does the Tiger·tec Silver coating help in production? The Tiger·tec Silver coating enhances wear resistance and reduces built-up edge, contributing to longer edge life and more consistent part quality over serial production runs.

What finish can be expected with a 0.2 mm corner radius? A 0.2 mm corner radius supports fine finishing while maintaining sufficient edge strength, making the insert suitable for applications where surface quality is important.
