SCMT120412-RM4 WMP20G — Square Turning Insert for Stainless Steel, Tiger‑tec Gold (Walter Tools)

SCMT120412-RM4 WMP20G is a square, 90° turning insert designed for medium to heavy duty machining of stainless steels in demanding production environments

• Square 90° shape for stable cutting
• Tiger‑tec Gold coating for extended edge life
• Corner radius 1.2 mm for robust part finish
• Chipbreaker RM4 for controlled chip formation

Maximise process efficiency with a coated grade optimised for stainless steel

The combination of the WMP20G grade and Tiger‑tec Gold coating delivers a reliable cutting-edge performance under the heat and adhesion challenges typical of stainless steel (ISO M) machining. The coated carbide composition reduces tool wear and supports stable chip formation, which in turn lowers the frequency of tool changes and contributes to higher mean time between interventions. The result is a measurable improvement in cycle consistency and a more predictable production flow.

Consistent surface quality and tool stability for demanding operations

The square 90° insert geometry, together with a 1.2 mm corner radius, provides mechanical strength at the cutting edge and helps to absorb intermittent cutting forces. The RM4 chipbreaker is shaped for controlled chip segmentation in tougher stainless grades, reducing the risk of built-up edge and enhancing surface finishes. For shops requiring repeatable part quality, these features translate into reduced rework and better dimensional consistency.

Practical handling and application benefits for the workshop

Featuring a clearance angle of 7° and a nominal inscribed circle of 12 mm, this insert fits standard toolholders for SCMT-style tooling and is straightforward to seat and clamp. The design supports secure seating and repeatable indexation, which simplifies tool management and reduces set-up time. As a coated carbide insert in the Tiger‑tec Gold family, it is suited to a broad range of stainless steel operations from semifinishing to more robust turning tasks.
