SCMT060204-FM4 WSM20S square 90° indexable turning insert — Tiger‑tec Silver by Walter Tools

SCMT060204-FM4 WSM20S is a square 90° indexable insert designed for heavy‑duty turning and finishing of stainless steel and heat‑resistant superalloys

• Tiger‑tec Silver coated carbide grade WSM20S
• Optimised FM4 chipbreaker for secure chips
• 7° clearance and 0.4 mm corner radius
• Square 90° insert, size 06, thickness 02

Reliable machining of stainless steel and superalloys for constant productivity

The Tiger‑tec Silver coating combined with the WSM20S substrate provides a balanced resistance to heat and wear, which is essential when machining stainless steel and high‑temperature alloys. The coating technology reduces adhesion and protects the cutting edge against thermal degradation, enabling longer tool life under demanding conditions. This results in fewer indexings and a more predictable process, supporting consistent cycle times on production lines.

Secure chip formation and improved surface quality through geometry

Equipped with an FM4 chipbreaker and a 0.4 mm corner radius, the geometry promotes controlled chip flow and reduces the risk of built‑up edge on tough materials. The insert’s 7° clearance minimises rubbing while maintaining adequate cutting contact, which contributes to a better surface finish and reduced workpiece heat input. For shops seeking predictable outcomes, these features translate into fewer reworks and stable dimensional results.

Process reliability and efficiency for industrial turning operations

Offering high process reliability, the insert is engineered to support repeatable performance in serial production. Walter Tools development focuses on a robust cutting edge and broad applicability, which helps to shorten setup times and reduce tool inventory complexity. Favourable wear rates and thermal stability lower overall tool consumption, improving productivity and supporting cost‑efficient machining of challenging alloys.

Practical compatibility and selection guidance for toolrooms

The square 90° format and the SCMT ISO specification make this insert compatible with a wide range of standard turning toolholders for 90° cutting applications. The coated carbide construction suits both roughing and finishing passes depending on cutting data and holder rigidity. For customers seeking exact cutting speeds and feeds, the SCMT060204-FM4 WSM20S can be matched to holder choice and machine rigidity to achieve the intended balance of material removal rate and surface quality.
