This detailed product description presents the Wieländer+Schill BTR/BOR Z3 series drill bit, specifically developed for the most demanding metalworking and body repair tasks. This tool is an excellent choice for the precise and efficient machining of high-strength (HSS) and ultra-high-strength (UHSS) steels.
The BTR/BOR Z3 drill bit belongs to the Wieländer+Schill Separating Tools category, specifically strengthening the Drilling Tools segment. Its design and material guarantee a long service life and reliable performance even when drilling the hardest materials.
This specific model (part number: 620010) is the 3.0 mm diameter, 70 mm length version, which is ideal for creating precision holes in structural elements where traditional drills quickly wear out or break due to the high strength of the materials. The 3-edge design (Z3) ensures optimal chip evacuation and stability during the drilling process.
Material quality: The drill bit is made from a combination of HSS (High-Speed Steel) and VHM (Tungsten Carbide), which provides unparalleled hardness and wear resistance. This composite material usage enables the drilling through high-strength steels (e.g., modern vehicle body components).
Configuration: The Z3 designation means three cutting edges, which is ideal for harder materials. This design increases the rigidity of the drill and improves chip evacuation, thereby reducing the risk of overheating and increasing hole accuracy.
Hossz: The 70 mm length provides sufficient depth for most body and structural applications while maintaining tool stability.
Precision Drilling: Specifically tailored to the requirements of the body repair industry, where hole size and positioning are critical.
