CCMT120408-FM4 WMP20G – Bohr-/Aufbohrwendeschneidplatte / Drehwendeschneidplatte by Walter Tools, Tiger-tec Gold, for rostfreier Stahl

CCMT120408-FM4 WMP20G is a precision turning and boring indexable insert designed for machining rostfreier Stahl under medium to robust conditions

• Tiger-tec Gold coating for improved wear resistance
• FM4 chipbreaker for stable chip formation
• Rhombus 80° geometry for versatile turning and boring
• 7° clearance and 0.8 mm corner radius for dependable edge strength

Optimised process reliability through coating and geometry

The combination of the Tiger-tec Gold technology and the WMP20G grade provides a balanced mix of hardness and toughness tailored to rostfreier Stahl. The advanced coated carbide microstructure improves thermal resistance and reduces wear at elevated cutting temperatures, which leads to longer intervals between tool changes and fewer unscheduled stops. The FM4 chipbreaker supports predictable chip control, reducing the risk of entanglement and enabling stable cutting even when material properties vary. Together with the insert’s rhombus 80° form and a 7° clearance, the design promotes consistent cutting forces and smooth transitions from roughing to sem-finishing, helping to maintain process stability on turning and boring operations.

Practical benefits for productivity and surface quality

By favouring a cutting geometry with a 0.8 mm corner radius, the insert balances edge strength and achievable surface finish, which can reduce the need for secondary operations in many production setups. The WMP20G grade is formulated to manage the specific challenges of rostfreier Stahl, such as work hardening and high heat generation; this results in stable chip formation and a reduced tendency for built-up edge. For production environments where uptime and reproducibility matter, this means fewer tool indexings and more consistent component quality. The insert’s attributes support economical machining through improved tool life and predictable performance, contributing to a measurable reduction in per-part tooling costs over extended runs.

Integration, handling and application recommendations

The insert is supplied in the common CCMT120408-FM4 format, compatible with standard indexable holders for turning and boring that accept rhombic 80° inserts. Use the FM4 chipbreaker setting for general-purpose turning of rostfreier Stahl; adjust cutting parameters to the machine’s rigidity and the workpiece condition for best results. The geometry is suitable for both through-bore and external turning tasks where a balance of edge robustness and surface quality is required. For matching holders and clamping advice, refer to tooling documentation or request specific recommendations to align speeds, feeds and depth of cut with shop conditions. Proper coolant strategy and stable clamping will further extend tool life and maintain the consistent edge life that characterises Tiger‑tec Gold grades.

FAQ

What materials is this insert intended for?
The CCMT120408-FM4 WMP20G from Walter Tools is intended primarily for rostfreier Stahl and is optimised for the thermal and mechanical behaviour of such steels.

How does the Tiger‑tec Gold coating benefit performance?
The Tiger‑tec Gold coating on the WMP20G grade increases wear resistance and thermal stability, which helps to extend tool life and maintain cutting-edge integrity during extended runs.

Which chipbreaker should be used for mixed turning operations?
The FM4 chipbreaker integrated in this insert supports stable chip formation across a range of turning and boring conditions, making it suitable for mixed operations on rostfreier Stahl.

Is the insert suitable for both drilling/boring and external turning?
Yes, the CCMT120408-FM4 format and rhombus 80° geometry make it versatile for both boring and external turning tasks when used in compatible holders.

What are the key geometric values to consider when setting cutting data?
Important values include the 7° clearance angle and the 0.8 mm corner radius; these influence tool strength and achievable surface finish and should guide feed and radial depth settings.
