Drilling/Boring and Turning Indexable Insert SCMT09T304-MM4 WMP20S – for stainless steel, Walter Tools

SCMT09T304-MM4 WMP20S is a square 90° indexable insert engineered for demanding boring and turning tasks in stainless steel, offering a balanced geometry and a robust coating technology for secure chip formation.

• Tiger·tec Silver coating for improved wear resistance
• Specifically graded WMP20S for stainless steel
• MM4 chipbreaker for stable chip control
• Square 90° geometry with 0.4 mm corner radius

Reliable performance on stainless steel for predictable results

The insert’s core advantage is its WMP20S carbide grade combined with Tiger·tec Silver technology, designed to cope with the toughness and heat sensitivity of stainless steel. This pairing promotes stable cutting edges and reduced adhesion at the rake face, which in practice improves tool life and lowers the frequency of insert changes. The specification supports medium to robust cutting conditions, translating into fewer unexpected stoppages and a more predictable production flow.

Geometry and chip control that protect the workpiece and tool

A square 90° format with a 0.4 mm corner radius and a 7° clearance angle provides a firm platform for radial cuts and bore enlargements while helping to distribute cutting forces evenly. The MM4 chipbreaker is tuned for continuous, controllable chip formation in stainless steel, reducing the risk of built-up edge and improving surface finish. For operations where component integrity and repeatability matter, this geometry reduces the need for manual rework and supports tighter tolerances.

Process security that improves efficiency and reduces costs

Using a coated insert from a recognised tool family such as Tiger·tec Silver promotes consistent performance across batches and operators. The robust coating and the WMP20S grade maintain a sharp edge for longer, cutting down on downtime for insert index changes. This reliability, combined with proven chip control, enhances machining throughput and often leads to lower overall production costs per component, particularly in high-mix or long-run stainless steel applications.
