SNMG150612-RM5 WMP20G – Walter Tools indexable turning insert, Tiger‑tec Gold, 1.2 mm radius

The SNMG150612-RM5 WMP20G is a square 90° indexable insert engineered for medium to heavy-duty turning of stainless steels, offering a coated carbide grade optimised for secure chip formation and consistent surface finish

• Tiger·tec Gold coating for reliable edge life
• Optimised for stainless steel (ISO M) machining
• 1.2 mm corner radius for reproducible surfaces
• Negative 0° clearance for robust cutting action

Consistent performance from the Tiger‑tec Gold coating

The Tiger‑tec Gold coating is a multilayer, coated carbide technology designed to resist adhesive wear and support stable cutting edges when machining stainless steels. Coated carbide means the insert combines a hard substrate with protective layers that reduce friction and thermal damage; this leads to fewer edge failures and longer tool life. For production environments where downtime and tool change frequency impact throughput, the coating’s thermal and mechanical resilience translates directly into higher process reliability and lower overall cost per component.

Geometry and chip control for dependable turning

The square 90° form with a 1.2 mm corner radius and the RM5 chipbreaker provide two decisive benefits: mechanical strength at the cutting edge and controlled chip formation. A larger corner radius increases edge robustness for interrupted cuts and heavier passes, while the RM5 chipbreaker promotes manageable chip shapes in ductile, tough stainless grades. The insert’s negative 0° relief enhances cutting stability for plunge cuts and heavy cross‑section machining, making it suited to demanding turning operations where secure engagement and repeatable results matter.

Productivity advantages and application guidance

Selecting this grade reduces rework and stabilises cycle times in serial production. The coated carbide grade WMP20G is matched to ISO group M (stainless steels), where material toughness and build‑up at the cutting edge are typical challenges. Using this insert with appropriate cutting data — moderate cutting speeds, controlled feeds and adequate coolant or lubrication — will improve surface finish and extend edge life. The practical result is fewer tool changes, more consistent component quality and improved machine utilisation in batch and continuous turning operations.

Practical fitment and decision support for engineers

The insert is designed for standard indexable turning toolholders that accept SNMG‑form inserts with a 90° shape. Its RM5 chip control and geometry make it suitable for both roughing and semi‑finishing steps when process parameters are adapted to stainless steel behaviour. For teams specifying tooling, the combination of coating, grade and geometry provides a straightforward route to stabilise machining of austenitic and other stainless alloys. Application-specific recommendations can be provided to match holder, insert orientation and cutting data to the workpiece and machine capability.

FAQ

Which materials is this insert suited to?
The SNMG150612-RM5 WMP20G is formulated for stainless steels (ISO group M); the WMP20G grade and Tiger‑tec Gold coating support secure chip formation in these alloys.

What does the RM5 chipbreaker do?
The RM5 chipbreaker is engineered to produce short, controllable chips and to reduce the risk of entanglement, improving process stability when turning tough, ductile stainless steels.

Is the insert suitable for heavy cuts or interrupted machining?
Yes. The square 90° geometry combined with a 1.2 mm corner radius and negative relief provides enhanced edge strength for heavier depths of cut and interrupted conditions.

Can the insert be used for finishing operations?
When set with conservative cutting speeds and fine feeds, the coated grade and geometry can deliver reproducible surface quality suitable for semi‑finishing; final finishing may require a dedicated finishing grade depending on tolerance requirements.
