Due to a special geometry this drill bit is suitable for clean, splinter-free holes (exactly Ø 9.5 mm) in corrugated roof panels made from polycarbonate, acrylic glass or sheets made of nonferrous metals (perfect for aluminum sandwich panels). Quick grip of the screw thanks to simultaneous center mark. Exactly cylindrical bore thanks to the optimized cone transition.

Key details: In order to fix corrugated roof panels they must be fastened with roofing caps and stainless steel screws or with roofing screws with an additional seal.

To take the screws, holes must first be drilled at the high point of the corrugation. To allow for expansion, the drill bit has been designed with a diameter of 9.5 mm, so that the roof has the opportunity to expand or contract under hot and cold conditions.
