Abrasion-resistant size markings located outside the clamping range ensure long-lasting readability (from Ø 5.0 mm). The core diameter steadily increases towards the shank to guarantee maximum break stability during handheld use (from Ø 4.8 mm).

Extreme 2 is the specialist for handheld drilling in thin-walled materials, producing perfectly round holes with clean, nearly burr-free edges. The center point allows for precise spot drilling without drifting, and the specially ground shoulder cutting edges mill exact, round holes with clean edges (from Ø 4.8 mm).

The iron oxide alloy effectively protects against overheating. The non-slip shank features three milled clamping surfaces to prevent the drill from spinning in the chuck (from Ø 5.0 mm). There is an up to 50% increase in break strength and break stability.

Start immediately after setting; centering is not required. The consistently increasing core diameter towards the shank provides the highest break stability during handheld use (from Ø 4.8 mm).

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