This detailed product description presents the premium quality, 4-flute solid carbide milling cutter from Wieländer+Schill, specifically designed for machining the hardest materials such as Usibor, Boron, BTR, as well as ultra- and mega-high-strength steels, and for removing spot weld points. This tool is part of the VarioDrill WS 90 series, belonging to the category of separation tools, representing the cutting edge of professional body repair technology.
This 4-flute milling cutter is an excellent choice for work involving high-strength metals where precision and tool life are critical factors. The tool's design guarantees efficient material removal and a clean cutting surface even in the most demanding applications.
The primary areas of application for the milling cutter include machining special high-strength steels (such as Boron or Usibor) found in modern vehicle bodies, and the precise and fast removal of spot welds without damaging the surrounding material. The 8 mm shank diameter ensures stability and compatibility with appropriate holding systems.
The use of high-quality solid carbide (VHM) material provides exceptional wear resistance and thermal stability, significantly increasing the tool's service life, especially under high load.
The product specifications have been optimized for maximum performance and reliability.

For maximizing performance and increasing tool life, the use of suitable cutting fluid is recommended.
The silicone-free BTR Fluid cutting oil significantly extends the life of milling cutters, drills, and reamers when processing high-strength automotive body steels. This fluid ensures optimal cutting performance and reduces friction and heat generation.
| Product | Package contents | Part number | Advantages |
|---|---|---|---|
| BTR/BOR Fluid | 125 ml | 628000 | Increases tool life, optimal cutting performance |
| BTR/BOR Fluid | 50 ml | 648007 | Increases tool life, optimal cutting performance |
These accessories are essential for the long-term, reliable operation of the tools when machining the hardest materials.
This milling cutter is part of the Wieländer+Schill separation tool portfolio, specifically tailored for the special requirements of the body repair industry. Modern vehicles increasingly use high-strength steel alloys to reduce weight and increase safety. Machining these materials with conventional tools is extremely difficult, resulting in rapid wear and poor cutting quality. The Z4 milling cutter offers a professional solution to these challenges, ensuring fast, clean, and safe operation.
The 44 mm length and 8 mm diameter create an ideal balance between rigidity and accessibility, enabling effective access to hard-to-reach spot welding points as well. The use of the tool minimizes the need for secondary repairs, thereby increasing workshop efficiency.
