Abrasion-resistant size markings, placed outside the clamping area, ensure permanently good legibility (from Ø 5.0 mm). The core diameter constantly increases in the direction of the shank for maximum breakage stability during freehand use (from Ø 4.8 mm).

Extreme 2 is the specialist for freehand drilling in thin-walled materials, producing circular holes with clean, virtually burr-free edges. The centre point enables precise spot drilling without running off, and the specially ground shoulder cutting edges mill exact, circular holes with clean edges (from Ø 4.8 mm).

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

Start immediately after setting; no centre punching is necessary. The constantly increasing core diameter in the direction of the shank provides the highest fracture stability in freehand 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 profiled materials (as well as tubes without pre-graining) where precise and clean holes are required. It is also very suitable for drilling wood and plastics.
