TCMT16T308-MM4 WMP20S — triangle 60° indexable insert, Tiger·tec Silver, for stainless steel — Walter Tools

A TCMT16T308-MM4 WMP20S triangle insert engineered for reliable turning of stainless steel under medium to robust conditions, combining advanced coating technology with a controlled chipformer for process stability

• Tiger·tec Silver coating for process security
• Optimised chip control MM4
• Triangle 60° with 0.8 mm corner radius
• Engineered for stainless steel M-group

High process reliability through advanced coating and grade

The use of Tiger·tec Silver together with the WMP20S carbide grade provides a clear advantage when machining stainless steel: improved thermal resistance and reduced tendency for built-up edge translate into stable cutting and longer intervals between index changes. The coated hardmetal is designed to handle the heat and toughness typical of M-group materials, so tool life is extended and the repeatability of components is increased. This technical combination supports higher material removal rates while maintaining surface integrity.

Consistent surface finish thanks to geometry and chip control

A triangle 60° shape with 0.8 mm corner radius and the MM4 chipbreaker optimise the contact geometry and chip formation for turning tasks. The modest corner radius balances edge strength and finishing capability, reducing the risk of edge chipping in interrupted cuts. With a 7° clearance and a compact T3 thickness in a 16 mm plate format, the insert offers rigidity and clearance to minimise rubbing, leading to improved surface finish and predictable dimensional results in series production.

Practical advantages for workshop integration and cost efficiency

The insert's specification makes it suitable for a range of turning operations where stainless steel is predominant, from semi-finishing to more robust cuts. The standard triangular format allows for multiple indexing positions, which reduces tooling cost per component. The MM4 chip control helps avoid long, stringy chips that interrupt cycle times, enhancing machine uptime. Selecting this insert allows process engineers to achieve a balance of productivity and tool economy while maintaining component quality.

FAQ

What materials is this insert suitable for?
The TCMT16T308-MM4 WMP20S is designed primarily for machining stainless steel (ISO group M) and supports stable chip formation and edge life when working with these materials.

What does the MM4 chipbreaker do?
The MM4 chipbreaker on this insert controls chip shape and evacuation, helping to avoid long chips and improving process security during turning operations with stainless steel.

How does the Tiger·tec Silver coating benefit production?
Tiger·tec Silver coating increases thermal resistance and reduces built-up edge, which in turn extends effective edge life and supports consistent surface quality with the TCMT16T308-MM4 WMP20S.
