This detailed product description presents a high-performance, specially designed drill bit manufactured by Wieländer+Schill, engineered for the precise removal of spot welds. This Variantic series cutting tool is the ideal choice for professional body repair work, especially for use with the VarioDrill WS 90 drilling machine.
The Variantic Z3 cutting head with article number BMWA9500697 is a key tool for separating body panels. It is specifically optimized to quickly and efficiently remove spot welds without damaging the surrounding metal structure. The use of high-quality material and special geometric design guarantees a long service life and reliable performance even under intensive, daily use.
This drill bit falls into the OEM (Original Equipment Manufacturer) recommendations category, with special consideration for BMW vehicle repair procedures, ensuring work is performed according to factory specifications.
Precise Spot Weld Removal: The design of the drill bit allows for fast and clean penetration of weld spots, minimizing heat impact and metal flare.
Variantic Compatibility: Specifically designed for the VarioDrill WS 90 optimized for the drill machine, ensuring perfect fit and maximum efficiency within the system.
Excellent Material Quality: The tool, made from a combination of carbide (Tungsten Carbide) and HSS (High-Speed Steel), ensures outstanding wear resistance and thermal stability.
Z3 Toothed: The three-flute (Z3) design results in optimal chip evacuation and stable cutting behavior, which is particularly advantageous when machining thicker or multi-layered materials.
OEM Compliance: A tool compliant with BMW specifications, essential for dealership workshops and quality aftermarket repairs.

Variantic drills represent the cutting edge of the Wieländer+Schill tool range, where traditional drilling techniques are combined with the special requirements for spot weld removal.
Anyagösszetétel: The tool body is made of HSS base material, which ensures the necessary flexibility and toughness. However, the cutting edges are equipped with carbide inserts or coatings (depending on the exact specification, but the „Carbide, HSS” marking suggests higher hardness and service life), which is essential for drilling through hard, often multi-layered steel of spot welds.
Geometry (Z3): The design of the three cutting edges (Z3) creates a balance between fast material removal and tool stability. This configuration reduces vibration, which is particularly important for work on thin sheets where excessive vibration can cause deformation. The special geometry of the edge shape minimizes friction, thereby reducing overheating of the drill head.
Sizing (Ø 8 mm x 44 mm): The 8 mm diameter is ideal for standard-sized spot welds, allowing for the complete removal of the weld seam without the drill leaving a hole that is too large on the sheet. The 44 mm length provides sufficient depth for most structural body parts.
For maximum service life and performance, it is recommended to perform drilling with a suitable coolant, especially when working with thicker or high-strength steels. Speed control of the VarioDrill WS 90 drill is crucial: lower speed with higher torque is ideal for harder spots, while higher speed allows for faster penetration in thinner layers.
This drill bit reflects the commitment to professional body repair technology, ensuring fast, clean, and safe work.
