SCMT09T304-RM4 WMP30G drilling/turning indexable insert, Tiger·tec Gold, for rostfreier Stahl — Walter Tools

The SCMT09T304-RM4 WMP30G is a coated carbide indexable insert designed for turning and boring operations on rostfreier Stahl, combining stable chip formation with robust cutting-edge performance.

• Tiger·tec Gold coating for long tool life
• Optimised RM4 chipbreaker for stable chips
• Designed for rostfreier Stahl machining
• Square 90° format with 0.4 mm corner radius

Consistent edge life for steady production

The Tiger·tec Gold grade delivers a coated carbide substrate engineered for higher wear resistance and thermal stability. For workshop managers and production engineers this translates into fewer insert changes and more predictable process windows. The combination of the grade and the insert’s geometry promotes durable cutting edges, reducing the risk of edge breakdown when machining the tough and heat-generating demands of rostfreier Stahl. The result is measurable productivity gains through longer tool life and less unscheduled downtime.

Precise chip control and improved surface quality

The RM4 chipbreaker is tailored to manage chip formation during medium to heavy-duty cuts. By producing short, controlled chips, the insert lowers the chance of surface damage and improves coolant penetration to the cutting zone. The 0.4 mm corner radius and 7° clearance angle balance robustness with finishing capability: the radius supports stronger edge retention under interrupted cuts, while the relief angle reduces rubbing and heat build-up. For applications where consistent finish and repeatable dimensions are required, this insert offers a reliable compromise between strength and form accuracy.

Simple integration and predictable results

Presented in a square 90° format, the insert fits many common toolholders and offers four usable corners, supporting economical index changes in production. Identification by the designation and series makes inventory handling straightforward: the Tiger·tec Gold series and the WMP30G grade are optimised specifically for rostfreier Stahl, ensuring compatibility with material behaviour governed by ISO 513 M-classifications. With clear specifications and a standardised geometry, the insert facilitates reproducible cutting conditions and easier process documentation for quality assurance.

FAQ

What materials is this insert suitable for?
The SCMT09T304-RM4 WMP30G insert from Walter Tools is specified for machining rostfreier Stahl; the WMP30G grade and Tiger·tec Gold coating are optimised for the toughness and heat characteristics of this material group.

How does the RM4 chipbreaker affect cutting performance?
The RM4 chipbreaker creates short, manageable chips and reduces the risk of built-up edge, which improves surface quality and process stability when using the SCMT09T304-RM4 WMP30G in turning or boring applications.

Which cutting edge geometry supports roughing and finishing?
The combination of the 0.4 mm corner radius and 7° clearance angle gives a balance between robust cutting for higher feeds and the ability to achieve fine surface finishes with appropriate feed and speed settings using this Walter Tools insert.

How many cutting edges are available per insert and what is the form factor?
The square 90° format provides four usable cutting corners per insert, making the SCMT09T304-RM4 WMP30G a cost-effective option for shops that require frequent indexing and predictable replacement intervals.

Is the insert compatible with common toolholders?
Yes; the SCMT09T304-RM4 WMP30G follows standard insert geometry and can be mounted in compatible holders designed for square 90° turning and boring inserts—confirming holder seat dimensions ensures correct seating and performance.
