CNMG160612-MM5 WMP20G — Walter Tools indexable turning insert for stainless steel, Tiger·tec Gold

CNMG160612-MM5 WMP20G is a rhombic 80° indexable turning insert designed for machining stainless steels in medium to robust turning operations

• Tiger·tec Gold coating for wear resistance
• Optimised WMP20G grade for stainless steel
• Rhombic 80° form with 1.2 mm corner radius
• MM5 chipbreaker for reliable chip control

Consistent cutting performance for challenging stainless steel work

The CNMG160612-MM5 WMP20G insert combines a coated-carbide substrate with the Tiger·tec Gold technology to address common issues when machining stainless steels, such as high ductility and a tendency to form built-up edge. The WMP20G grade is formulated to promote stable chip formation and to preserve the cutting edge under fluctuating thermal loads. This results in fewer interruptions for tool changes and a more predictable production rhythm. The rhombic geometry contributes to versatile approach angles, enabling process planners to favour either higher material removal or improved surface finish depending on the setup.

Improved process reliability through chip control and edge stability

A dedicated MM5 chipbreaker and the negative 0° relief angle reduce the risk of long, entangling chips and support secure evacuation in continuous turning. The 1.2 mm corner radius balances edge strength and surface integrity, helping to avoid premature edge chipping in medium to robust cuts. By using an insert that is optimised for these conditions, workshops can expect more consistent part quality and less rework. The combination of grade and chipformer also contributes to repeatable results when switching between similar stainless steel alloys, lowering scrap rates and downtime.

Practical integration and benefits for production workflows

The rhombic 80° insert form enables flexible insert indexing and economical use of the cutting edges. Its compatibility with common toolholder platforms makes retrofitting straightforward; the plate thickness and seat geometry ensure stable clamping and minimal vibration when secured correctly. Process engineers benefit from the trade-off between edge life and achievable feeds: the coated grade extends usable life without compromising cutting security in tougher stainless applications. When planning tool lists, include this insert where a balance of surface finish, tool life and chip control is required.

FAQ

What materials is this insert intended for?
This insert is designed primarily for machining stainless steels; the WMP20G grade and Tiger·tec Gold coating support secure chip formation and edge life in those materials.

How does the MM5 chipbreaker affect performance?
The MM5 chipbreaker improves chip control and evacuation, reducing the risk of entangling chips and contributing to a more consistent surface finish with fewer interruptions.

Can the rhombic 80° geometry be used for finishing passes?
Yes, the rhombic 80° form with a 1.2 mm corner radius offers a balance between edge strength and surface quality suitable for both medium finishing and robust turning strategies.

Is this insert compatible with standard CNMG toolholders?
The insert follows the CNMG designation and is compatible with standard CNMG toolholders designed for rhombic 80° inserts, provided the clamping and seat meet the toolholder’s specifications.

What advantage does Tiger·tec Gold technology provide?
Tiger·tec Gold coating enhances wear resistance and thermal stability, which helps maintain edge integrity under the elevated temperatures typical when machining stainless steels.
