This detailed product description presents the premium quality Wieländer+Schill 6.6 mm diameter pilot (center drill) accessory, specifically designed for precise hole machining, particularly for use with 100° countersinking tools. This component is essential during body repair and metalworking operations where accurate center determination is critical.
The 6.6 mm pilot center drill belongs to the precision tools category, and the WS Wieländer+Schill represents recognized quality. Its main function is to position the 100° countersinking tool with extreme accuracy, ensuring that the countersinking or drilling starts at the desired location, minimizing the chance of error. This feature is particularly valuable in applications where dimensional accuracy and surface integrity are primary concerns.
This precision tool is Separating Tools and among the Drilling Tools category, and is an ideal choice for professional workshops where reliability and long service life are expected.
Precise Positioning: The tool's design guarantees the precise centering of the 100° countersinking tool, which is essential for a clean and flawless hole start.
Excellent Material Quality: Made of steel, which ensures the necessary hardness and wear resistance during frequent industrial use.
Optimized Dimensions: The 6.6 mm diameter specifically fits the countersinking tools designed for it, while the 2.18 mm shank diameter ensures a stable fit in the chuck.
Könnyű Kezelhetőség: Its extremely low weight (0.010 kg) facilitates handling and reduces fatigue during longer work sessions.
The technical specifications of the product ensure compatibility and reliable performance in professional applications.

This 6.6 mm pilot insert is part of Wieländer+Schill's broader Separating Tools range, which are specifically tailored to the demands of the automotive repair industry. Modern vehicle bodies often contain high-strength steels and aluminum alloys that require special precision for machining.
The use of the pilot is essential for precise countersinking during the process. When a countersunk hole needs to be created for a screw head or a fastener, the pilot first creates a small, stable guide hole. This guide hole prevents the larger diameter countersinking tool from slipping on the metal surface (so-called „wandering”), which is especially critical on thinner sheets or already painted surfaces. The 6.6 mm size corresponds to the most frequently used countersinking diameters, ensuring a perfect fit.
The steel material guarantees that the tool can withstand the high shear forces and friction generated during drilling without wearing out or breaking prematurely. Tool maintenance is simple: cleaning after use and proper storage ensure long-term reliability.
Wieländer+Schill is committed to the highest quality standards. Manufacturing processes are subject to strict quality control, which is supported by the company's ISO certifications:
ISO 9001: Quality Management System Certificate.
ISO 14001: Environmental Management System Certificate.
These certifications ensure that consistently high-quality procedures are applied during the manufacturing of the 617247 part number pilot center drill, which is a direct benefit to the user in terms of tool reliability and lifespan.
This precision tool is the ideal accessory for any professional toolkit active in the field of body repair technologies (XSeries – Professional Riveting Technology).
