A European manufactured hammer drill bit with a patented, high-volume, multi-flute that quickly channels the drilling dust from the hole, saving both time and money. Due to its aggressive design, the fast and durable carbide tip allows easy centring and spot drilling. Designed for regular professional use, providing excellent performance in the toughest of materials. Also excellent for drilling in high resistance materials such as Green Concrete or Engineering Brick. The unique reinforced flute geometry transfers more impact energy from the rotary hammer to the drill head, reducing stress for user and power tool. The design and technology innovations of these SDS drill bits significantly raised the performance parameters of drilling speed and life .
