SNMG120412-RM5 WMP20S Drehwendeschneidplatte – Square 90°, 1.2 mm radius, Walter Tools

SNMG120412-RM5 WMP20S is a square turning insert designed for reliable machining under medium to heavy conditions, especially for stainless steel, and forms part of the Tiger·tec Silver series

Tiger·tec Silver coated carbide
Optimised for stainless steel (M-group)
Square 90° geometry, 1.2 mm corner radius
0° negative rake for robust cutting

Consistent chip control and longer edge life for stable production

The combination of the WMP20S grade and the Tiger·tec Silver coating provides a balanced performance that emphasises stable chip formation and wear resistance. In practice, this means fewer interruptions for edge changes and more predictable tool life in series production. The integrated RM5 chipbreaker supports secure chip evacuation when machining tough, ductile materials, improving process security and reducing manual rework. Operators benefit from less downtime and a more consistent surface finish when an insert with these properties is specified.

Designed for stainless steel to reduce build-up and thermal issues

Machining stainless steel often causes material to adhere to the cutting edge and generates high cutting temperatures. The coated substrate and the chemical-physical properties of the grade help to reduce built-up edge and improve heat management. Using an insert with this specification supports a safer chip flow and helps maintain cutting-edge geometry under elevated thermal loads, which in turn contributes to more repeatable part quality and reduced secondary operations.

Geometry and handling that support versatile turning tasks

The Square 90° form combined with a 1.2 mm corner radius makes the insert suitable for a range of turning tasks where strength at the corner and the ability to handle interrupted cuts are required. The 0° negative rake increases edge robustness and provides more stable cutting in heavier engagements. This geometry is particularly useful where tool strength is preferred over maximum sharpness, for example in finishing and medium roughing of stainless steel where chatter and edge wear must be avoided.

Practical benefits for workshop productivity and process planning

Specification of this insert simplifies process planning: the clear material group applicability (M) reduces the choice overload when selecting grades for stainless applications, and the coated-carbide construction ensures a good compromise between economy and performance. The format and chipbreaker support automated production cycles by lowering the frequency of insert changes and enabling longer periods of consistent operation. For workshops aiming to increase throughput without compromising component quality, the insert offers a pragmatic balance between durability and surface result.
