• RM4 chipbreaker for controlled chips

High-performance grade for demanding materials

The WSM30S grade of the Tiger·tec Silver series is a coated carbide solution designed to tackle materials that create heat and work harden, such as stainless steel and heat-resistant superalloys. Its formulation focuses on thermal resistance and edge stability to reduce edge build-up and prolong interval between index changes. For production environments, this means improved process reliability and fewer interruptions to the machine cycle, translating into higher effective throughput without compromising dimensional accuracy.

Geometry and chip control that stabilise the cut

A triangle 60° insert form, with a 0.4 mm corner radius and a free angle of 7°, provides a balance between cutting strength and surface finish. The RM4 chipbreaker is tuned to break and evacuate chips efficiently under interrupted or continuous cutting conditions, reducing the risk of recutting and surface damage. These geometric choices work together to maintain a steady cutting force, which helps preserve spindle life and contributes to consistent component tolerances in serial production.

Process benefits that reduce overall cost per part

Using a coated, application-oriented grade together with the insert's geometry yields measurable process advantages: fewer indexing events, better surface integrity and lower scrap rates. The combination of Tiger·tec Silver wear resistance and a precise chipbreaker improves tool life, so tooling expenditure per finished part falls. In addition, the insert’s tolerance class M supports predictable performance in repeat production, which simplifies process planning and reduces downtime from unexpected tool wear.

Recommended applications and material compatibility

This insert is suitable for machining tasks classified under ISO groups M and S, meaning it is intended for stainless steels and heat-resistant superalloys (including some titanium applications depending on geometry and cut parameters). The grade and chip control are especially helpful when machining materials that dissipate heat poorly and impose high thermal loads on the cutting edge. For best results, select cutting parameters matched to the workpiece alloy and the machine’s rigidity; technical advice is available if more detailed parameterisation is required.

FAQ

What materials is this insert suited for?
The TCMT090204-RM4 WSM30S insert is formulated for stainless steels (ISO group M) and heat-resistant superalloys (ISO group S), offering thermal resistance and edge stability for those alloys.

How does the RM4 chipbreaker influence machining?
The RM4 chipbreaker on this insert promotes predictable chip formation and evacuation, which reduces the risk of recutting and helps maintain surface quality during both continuous and interrupted cuts.

Which geometry advantages does the triangle 60° form provide?
A triangle 60° form gives three usable cutting edges per insert and a good compromise between strength and clearance; combined with a 0.4 mm corner radius and 7° free angle, it supports repeatable dimensional control and a stable cutting process.

Can this insert be used for both drilling and turning operations?
Yes, the TCMT090204-RM4 WSM30S is specified as a drilling/boring and turning indexable insert; the combination of grade and geometry makes it versatile for related machining tasks where the material and cutting conditions are appropriate.

What is the key benefit of the Tiger·tec Silver series here?
Tiger·tec Silver provides enhanced wear resistance and temperature management, which extends tool life and improves process reliability when machining tough-to-cut alloys with this insert.
