Start immediately after preparation, no further punching required. An iron oxide alloy effectively protects against overheating. Abrasion-resistant size markings placed outside the clamping area ensure permanently good readability (from Ø 5.0 mm). Round holes have clean, almost burr-free edges. The specialist for handheld drilling in thin-walled materials allows for precise point drilling without drifting, thanks to the center point. Specially ground shoulder cutting edges mill exact, round holes with clean edges (from Ø 4.8 mm).

Up to 50% increased break resistance. The non-slip shank with three milled clamping surfaces prevents the drill from spinning in the chuck (from Ø 5.0 mm). The constantly increasing core diameter towards the shank ensures the highest break stability during handheld use (from Ø 4.8 mm).

Application examples: For drilling sheet metal and thin-walled profile materials (as well as pipes without pre-toothing), where precise and clean holes are required. Also very suitable for drilling wood and plastics. For use in alloyed and unalloyed steels up to 900 N/mm² tensile strength.
