Abrasion-proof size markings, placed outside the clamping area, ensure permanently good legibility (from Ø 5.0 mm). Start immediately after setting; no more center punching is necessary. Circular holes feature clean, almost burr-free edges. The extreme DEWALT 2 center point enables precise spot drilling without running off, and specially ground shoulder cutting edges mill exact, circular holes with clean edges (from Ø 4.8 mm).

The extreme 2 is the specialist for freehand drilling in thin-walled materials, offering up to 50% increased breaking strength. The anti-slip shank with three milled clamping surfaces prevents the drill from spinning in the chuck (from Ø 5.0 mm). The core diameter constantly increases in the direction of the shank for the highest breakage stability in freehand use (from Ø 4.8 mm). An iron oxide alloy effectively protects against overheating.

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 drilling is required. It is also very suitable for drilling wood and plastics.
