SCMT09T304‑MM4 WMP20G — Square Turning Insert (Tiger·tec Gold) for Stainless Steel, Walter Tools

The SCMT09T304‑MM4 WMP20G is a square indexable turning insert engineered for medium to robust machining of stainless steel, offering coated‑carbide durability and stable chip formation in demanding conditions.

• Tiger·tec Gold coating for stainless steel performance
• 7° clearance angle for secure chip control
• 0.4 mm corner radius for reliable edge strength
• Square 90° form for versatile turning and boring

Consistent cutting performance for stainless‑steel workpieces

The Tiger·tec Gold‑based grade WMP20G is formulated to address the specific challenges of machining stainless steel — toughness, built‑up edge tendency and high heat generation. As a coated carbide solution, the insert supports controlled cutting temperatures and predictable wear behaviour; this translates into longer tool life and fewer unplanned tool changes in serial production. The MM4 chipbreaker contributes to stable chip control, reducing the risk of entanglement and improving surface integrity on finished components.

Geometry and edge design that secure process reliability

A square 90° plate shape together with a 0.4 mm corner radius balances edge strength and versatility for plunge cuts, general turning and light boring operations. The specified 7° clearance angle helps to avoid rubbing and reduces cutting forces where material stickiness is a concern. The T‑thickness construction (T3) provides mechanical support for the cutting edge under moderate to heavy cut conditions, while the MM4 groove geometry is tuned to promote predictable chip formation when machining austenitic and other stainless grades.

Production advantages for workshops and toolrooms

As an indexable insert, the SCMT09T304‑MM4 format allows rapid replacement and multiple usable edges, supporting high uptime and efficient tool‑room logistics. The combination of the WMP20G grade and Tiger·tec Gold coating yields a favourable trade‑off between wear resistance and toughness, making it suitable for series production where reproducible surface finish and dimensional stability are required. Compatibility with common ISO‑style toolholders and the standard SCMT geometry ensures straightforward integration into existing tool assemblies and quick changeover in multi‑station setups.
