SCMT09T304-RM4 WMP20G — Square 90° turning/boring indexable insert with Tiger·tec Gold coating (Walter Tools)

The SCMT09T304-RM4 WMP20G is a square 90° indexable insert designed for robust turning and reboring tasks, optimised for machining rostfreier Stahl under medium to heavy cutting conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised RM4 chipbreaker for stable chips
• Square 90° form with 0.4 mm corner radius
• 7° clearance for secure cutting-edge stability

Stable cutting in rostfreier Stahl for fewer interruptions

The coated carbide WMP20G grade, part of the Tiger·tec Gold series, is developed specifically to address the challenges of machining rostfreier Stahl: high toughness, tendency to form built-up edge and elevated cutting temperatures. The premium coating improves thermal and abrasive resistance, which translates into longer tool life and more consistent component quality. This results in fewer tool changes and a more predictable production rhythm, supporting higher overall process efficiency.

Predictable chip control and enhanced edge life

The RM4 chipbreaker geometry is engineered to deliver controlled fragmentation and smooth evacuation of chips in tougher material groups. Combined with the coated substrate, the geometry promotes stable cutting forces and reduces the risk of workpiece damage from erratic chip formation. The outcome is a balance between reliable chip control and extended edge integrity, reducing rework and improving first-pass yield.

Robust geometry for consistent surface finish

The square 90° form with a 0.4 mm corner radius provides a compromise between edge strength and surface quality: the radius adds toughness for interrupted cuts while still enabling acceptable finishes on the component. A 7° clearance angle reduces flank rubbing and helps maintain the cutting edge at higher temperatures commonly encountered when machining rostfreier Stahl. The insert’s size 09 and thickness T3 ensure mechanical stability in typical toolholders for turning and boring tasks.

Practical deployment and process integration

This indexable design suits both turning and reboring applications where material conformity and process security are priorities. The combination of grade and chipbreaker makes the insert appropriate for medium to robust cutting parameters; it is particularly effective where consistent chip behaviour and wear resistance are required. Technical teams often value the repeatability and reduced variance in cutting performance, which simplifies process setup and quality control during series production.
