SCMT09T308-RM4 WMP30G — Square indexable insert for turning, Tiger·tec Gold, Walter Tools

SCMT09T308-RM4 WMP30G is a square 90° indexable insert designed for turning and boring applications in stainless steel, optimising both edge life and chip control

• Tiger·tec Gold coated carbide grade WMP30G
• RM4 chipbreaker for secure chip control
• Optimised for stainless steel (ISO group M)
• 0.8 mm corner radius for robust edge stability

Secure chip control keeps production flowing

The coated carbide WMP30G grade, part of the Tiger·tec Gold series, combines a wear-resistant coating with substrate properties tailored to the demands of machining stainless steel. The RM4 chipbreaker is engineered to produce consistent chip segmentation under the high-heat, adhesive conditions typical for this material group; this results in fewer interruptions for chip clearing and a more predictable cycle time. For production planning, that means improved process reliability and fewer unscheduled stops, improving overall equipment effectiveness.

Stable edges and consistent surface quality

A square 90° insert form with a 0.8 mm corner radius delivers strong edge support and resistance to thermal and mechanical shock, which is crucial when turning tough alloys. The 7° clearance angle reduces rubbing and helps maintain cutting geometry under load, while the insert thickness (T3) contributes to rigidity in the toolholder. Together these characteristics help to produce repeatable surface finishes and dimensional consistency, reducing downstream rework and inspection time.

Easier tool management, longer intervals between changes

The SCMT designation corresponds to common toolholder systems, simplifying inventory and replacement on the shop floor. The coated, grade-optimised insert promotes longer edge life in medium to robust cutting conditions, often translating into lower tooling costs per component and less frequent intervention by operators.

FAQ

What materials is this insert optimised for?
The SCMT09T308-RM4 WMP30G is optimised for stainless steel (ISO group M), offering secure chip formation and stable cutting edges under the high heat and toughness typical of these alloys.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker promotes controlled chip fragmentation during turning operations, which reduces the risk of long, tangled chips and supports uninterrupted production when machining stainless steel.

Can the insert be used in standard toolholders?
Yes, the SCMT designation corresponds with common insert and toolholder systems for turning and boring, simplifying tool changes and stockkeeping.

What performance advantage does Tiger·tec Gold provide?
The Tiger·tec Gold coating increases wear resistance and thermal stability, extending edge life under medium to robust cutting conditions and improving process consistency for the WMP30G grade.

What corner radius is recommended for roughing vs finishing?
The 0.8 mm corner radius on this insert provides a balance between edge strength and surface finish; it is particularly suitable for stable roughing and semi-finishing when robustness is required.
