TCMT110208-RM4 WMP20G – Turning indexable insert, 7° clearance, 0.8 mm corner radius (Walter Tools)

TCMT110208-RM4 WMP20G is a coated carbide turning insert designed for reliable machining of stainless steel in medium to robust conditions

• Turning insert TCMT110208-RM4 WMP20G by Walter Tools
• Tiger-tec Gold coating for longer tool life
• 7° clearance, 0.8 mm corner radius for robust cuts
• Optimised for stainless steel (ISO group M)

Improved process stability for stainless steel components

The combination of the WMP20G grade and the Tiger·tec Gold coating yields a coated carbide solution tailored to the demands of machining stainless steel. The grade supports secure chip formation and high edge stability under the higher temperatures and built-up edge tendencies typical of M-group materials. As a consequence, cycle-time consistency and component quality are enhanced, while the need for frequent insert changes is reduced.

Consistent chip control and edge protection for challenging feeds

With the RM4 chipbreaker and the Tiger·tec Gold surface treatment, the geometry directs chips away from the cutting zone and reduces edge wear during interrupted cuts. The chipbreaker is optimised for stainless materials that are prone to long, stringy chips; this results in safer swarf behaviour and fewer secondary operations to clear chips. The coated substrate supports a stable cutting edge, improving surface finish and preserving dimensional accuracy during extended runs.

Versatile geometry that balances productivity and edge life

The triangular 60° form provides three usable cutting edges per insert, enabling efficient indexability and cost-effective usage. The 7° clearance angle and 0.8 mm corner radius are selected to withstand moderate depths of cut while limiting edge chipping, making the geometry suited to medium to robust machining strategies. This balance of shape and relief supports reproducible results on bars, shafts and general turned parts in stainless alloys according to ISO group M.

FAQ

What materials is this insert intended for? The TCMT110208-RM4 WMP20G is intended primarily for stainless steel machining (ISO group M) and is engineered to handle the toughness and heat sensitivity of these alloys.

How does the Tiger·tec Gold grade improve performance? The Tiger·tec Gold grade provides enhanced wear resistance and edge stability on the coated carbide substrate, extending insert life and maintaining consistent surface finish during production.

What benefits does the RM4 chipbreaker offer in practice? The RM4 chipbreaker promotes controlled chip formation and evacuation when turning stainless steel, reducing the risk of long, entangling chips and improving operational safety.

Is the triangular shape advantageous for production runs? Yes; the triangular 60° geometry offers three indexable cutting edges per insert, which increases cost-efficiency and reduces tool-change frequency in batch and continuous turning operations.

Can this insert be used for light finishing passes? The combination of the 0.8 mm corner radius and the 7° clearance makes the insert suitable for medium to robust operations; finishing passes are possible but should be selected according to component tolerance and surface finish requirements.
