This detailed product description presents the Wieländer+Schill 120° countersink cutter, an essential tool for preparing holes necessary for the precise installation of screws and rivets. Thanks to its excellent quality HSS (High-Speed Steel) material, it guarantees durability and reliable performance during the most demanding bodywork and metalworking tasks.
The 120° countersink cutter is specifically designed to create perfectly fitting, conical sinkings on metal surfaces. This operation is critically important for the flush, aesthetic, and functionally correct installation of countersunk head screws or rivets. The precise 120° angle ensures that the fastener head fits completely into the plane of the workpiece, avoiding protruding parts, which is especially important in vehicle repair and construction.
This tool belongs to the Wieländer+Schill category „Separating Tools,” specifically strengthening the segment of Drilling Tools and Milling Cutters / Drill Bits.
Precise Geometry: The 120° angle guarantees compliance with standards for countersinking, which is essential for professional fastening work.
Excellent Material Quality: High-Speed Steel (HSS) construction ensures the tool's long service life and resistance to high loads and wear.
Versatile Use: Ideal for screws and rivets where the goal is to fit the head flush.
Easy Clamping: Thanks to its 1/4″ shank diameter, it is compatible with most standard drill and machine drives.

The 120° countersink cutter is part of the Wieländer+Schill professional tool range, specifically developed for the special requirements of the vehicle repair industry.
Advantages of HSS (High-Speed Steel):
The choice of HSS material is intentional. This alloyed steel offers excellent resistance to the high temperatures generated by high rotational speeds. This ensures that the tool's sharpness and cutting performance are maintained over the long term, even when machining harder materials, such as high-strength steels. The service life of the tool is significantly extended compared to traditional carbon steel tools.
Ergonomics and Compatibility:
The 1/4″ shank diameter is standardized, allowing for quick and secure clamping in pneumatic or electric drills, as well as machines equipped with appropriate speed control. The compact dimensions (28 mm overall length) provide access even in tight spaces, which is a frequent challenge in modern vehicle body repair.
Precision in Fastening:
The quality of the countersinking directly influences the load-bearing capacity of the fasteners and the aesthetics of the surface. The 120° countersink angle provides a perfect base for the appropriately sized countersunk head screws, preventing material washout or cracking beneath the screw head. This is particularly important when repairing structural elements.
This countersink angle is the ideal choice for every specialist seeking the quality of Wieländer+Schill in body repair and metalworking processes where precision and reliability are fundamental requirements.
