High-performance cutting for stainless steel

The coated carbide grade WMP30G (Tiger·tec Gold technology) provides a balance of wear resistance and toughness that is optimised for machining stainless steel. The combination of the coating and substrate reduces heat-related edge degradation and minimises built-up edge, which leads to longer tool life and more consistent component quality. For workshops seeking predictable productivity, the coated grade supports repeatable cutting edge behaviour under medium to heavy conditions.

Stable chip formation and edge security

The integrated RM5 chipbreaker is designed to promote controlled chip segmentation when turning ductile, work-hardening materials. By breaking and evacuating chips reliably, the chipbreaker decreases the risk of entanglement and improves surface consistency. The insert’s 1.2 mm corner radius provides mechanical strength at the cutting edge, while the 0° (negative) rake ensures secure seating in the toolholder and reduces the chance of insert movement under heavy cut loads.

Material and coating explained for practical results

WMP30G is a coated carbide grade tailored to the specific demands of stainless steel: high toughness to resist chipping and a wear-resistant surface to combat abrasive effects. The Tiger·tec Gold layer enhances thermal stability and sliding resistance, which helps to prevent premature flank wear during interrupted cuts or where heat generation is elevated. In short, the grade is chosen to deliver process stability and repeatable surface finish for serial production.

Practical application and toolholder considerations

The square 90° insert format and the plate size designation (19 mm) make this insert suitable for a wide range of turning toolholders and facing operations. The thickness designation 06 and the negative 0° free angle should be matched with rigid clamping and an appropriate holder geometry to exploit the insert’s strength. For heavy engagement or interrupted cuts, the robust corner radius and RM5 geometry favour conservative entry angles and steady feed to maintain edge life. For tailored cutting data and holder compatibility, Metav Werkzeuge’s technical advisers can propose optimal pairings based on the specific stainless steel grade and part geometry.

FAQ

Which materials is this insert suitable for?
The SNMG190612-RM5 WMP30G turning insert from Walter Tools is designed primarily for stainless steel and performs well under medium to robust cutting conditions.

What advantage does the RM5 chipbreaker provide?
The RM5 chipbreaker on this insert promotes consistent chip segmentation and evacuation, reducing chip-related interruptions and supporting steady surface quality during turning.

How does the Tiger·tec Gold coating affect performance?
Tiger·tec Gold on the WMP30G grade increases thermal stability and wear resistance, which extends edge life and improves process stability when machining stainless steel.

What does a 0° (negative) free angle mean for tool setup?
A 0° (negative) free angle indicates a robust cutting face and secure insert seating; proper rigid clamping and suitable holder geometry are recommended to exploit the insert’s strength.

Is the 1.2 mm corner radius suitable for roughing operations?
Yes, the 1.2 mm corner radius provides added edge strength for roughing and interrupted cuts, offering a compromise between edge robustness and achievable surface finish.
