SNMG120412-RM5 WMP20G Drehwendeschneidplatte – Tiger·tec Gold coated insert for stainless steels | Walter Tools

SNMG120412-RM5 WMP20G is a square indexable turning insert designed for reliable machining of stainless steels under medium to robust cutting conditions

• Tiger·tec Gold coating for increased edge life
• Designed for stainless steel machining (ISO M)
• Square 90° insert with 1.2 mm corner radius
• RM5 chipbreaker for stable chip formation

Longer productive tool life through advanced coating technology

The combination of Tiger·tec Gold coating and the WMP20G grade provides a durable, coated carbide solution that extends edge life when facing the adhesion and heat-related wear typical of stainless steels. The coated microstructure reduces flank wear and supports consistent performance across a run of components, which in turn lowers tool change frequency and unplanned stoppages. For manufacturers seeking predictable consumable intervals, the insert’s design helps maintain surface quality while managing total machining costs.

Predictable chip control and process stability for turning operations

Built with an RM5 chipbreaker and a negative rake angle of 0°, the insert encourages secure chip formation when cutting ductile, work-harden­ing-prone materials. The square 90° geometry and corner radius 1.2 mm combine to reduce vibration and the risk of built-up edge, delivering improved surface finish and dimensional repeatability. These features translate into fewer secondary operations and less scrap, supporting higher first-pass yield in mixed-batch production.

Easy adaptation to existing toolholders and machining strategies

With the industry-standard SNMG designation and a compact size, the insert fits a wide range of holders and clamping systems, facilitating quick swaps during production changeovers. The standardised form factor simplifies inventory management, while the robust grade WMP20G is tuned for medium to heavy cuts in ISO M materials, enabling stable metal removal rates without sacrificing component integrity. Documentation-friendly dimensions and ISO grouping support straightforward process planning.

Economical performance: fewer interruptions, lower indirect costs

Optimised for stable chip formation and a resilient cutting edge, this insert helps reduce downtime caused by edge failure or poor chip evacuation. The cumulative effect is a leaner machining process with reduced operator intervention and cleaner machine runs. For operations targeting consistent batch throughput, the insert represents a balance between durability and controllable cutting forces, improving overall equipment effectiveness and contributing to predictable production schedules.

FAQ

What materials is this insert intended for?
The SNMG120412-RM5 WMP20G insert is specified for stainless steels (ISO M); the WMP20G grade is tuned to handle the toughness and heat characteristics of these alloys.

How does the RM5 chipbreaker affect machining performance?
The RM5 chipbreaker promotes consistent chip control and reduces the risk of long, stringy chips when turning stainless steels, contributing to process stability and improved surface finish with the Walter Tools insert.

Which insert geometry benefits roughing or finishing?
The square 90° geometry with a 1.2 mm corner radius offers a balance: robust enough for heavier cuts while still allowing acceptable surface quality for semi-finish operations when paired with suitable parameters.

Is this insert compatible with standard SNMG toolholders?
Yes, the SNMG120412-RM5 form follows industry SNMG dimensions and is compatible with standard toolholders designed for SNMG inserts.

What distinguishes the WMP20G grade from general-purpose grades?
WMP20G, part of the Tiger·tec Gold family, is a coated carbide grade optimised for reduced flank wear and improved edge stability in stainless steel turning compared with uncoated or generic grades.
