DCMT11T308-FW4 WSM20S — Indexable turning insert, Tiger·tec Silver, Walter Tools

The DCMT11T308-FW4 WSM20S is an indexable turning insert designed for machining stainless steels and heat‑resistant superalloys, optimising process stability with a robust coated carbide grade.

• Tiger·tec Silver coated grade WSM20S
• Optimised for stainless and superalloys
• Rhombic 55° form with 0.8 mm corner radius
• FW4 chipbreaker for secure chip control

Precision and process reliability in demanding materials

The insert combines the Tiger·tec Silver coating with the WSM20S carbide grade to deliver improved resistance to heat and abrasion when machining challenging materials. This combination supports stable chip formation and reduces the risk of built‑up edge when working with stainless steels and superalloys, which typically generate high temperatures at the cutting edge. The modest 7° clearance angle helps maintain a secure cut without excessive rubbing, while the coated grade increases resistance to flank wear, extending effective tool life and reducing downtime for regrinding or replacement.

Consistent chip control and improved surface finish

The FW4 chipbreaker is tuned to break and evacuate chips reliably in turning operations, preventing entanglement and protecting both the tool and the workpiece from damage. The rhombic 55° geometry, combined with a 0.8 mm corner radius, balances strength and sharpness to deliver a consistently good surface finish on contoured and stepped parts. For shops aiming to reduce secondary operations, this geometry provides a controlled cutting action that minimises the need for additional finishing, translating into measurable productivity gains on serial production.

Optimised handling and productivity for the shop floor

With a compact insert size and a T3 plate thickness, the design supports secure clamping and repeatable seating in standard toolholders. The grade’s suitability for ISO material groups M (stainless steels) and S (heat‑resistant superalloys and titanium) makes it a versatile choice across aerospace and energy applications where material behaviour is demanding. By combining robust edge stability with effective chip control, the insert reduces machining interruptions and contributes to a steadier, more economical production flow — an advantage for operations where consistent batch quality and reduced cycle time are priorities.

FAQ

What materials is this insert best suited for?
The DCMT11T308-FW4 WSM20S is designed primarily for stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), offering heat and wear resistance for these demanding materials.

How does the FW4 chipbreaker improve machining?
The FW4 chipbreaker promotes reliable chip segmentation and evacuation, reducing the chance of entangling chips and helping to maintain a consistent surface finish during turning operations.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances thermal and abrasion resistance of the cutting edge, which leads to improved tool life and stable cutting performance when machining tough or heat‑generating materials.

Can this insert be used in standard toolholders?
Yes; the insert’s rhombic 55° form and T3 thickness are compatible with conventional turning toolholders designed for DCMT‑style inserts, offering straightforward seating and clamping.

What does the 0.8 mm corner radius mean for component finish?
A 0.8 mm corner radius provides a compromise between edge strength and sharpness, supporting good surface quality while increasing resistance to chipping under interrupted or heavy cuts.
