The B-46551 is an European manufactured hammer drill bit with a patented, high volume multi-flute that quickly channels the drilling dust from the hole. Due to the aggressive design of the B-46551, the fast and durable carbide tip allows for easy centring and spot drilling. Designed for regular professional use and provides excellent performance in the toughest of materials. The B-46551 is also ideal for drilling 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 both the user and the power tool. The design and technology innovations of these Performance SDS-Plus Drill Bits significantly raises the performance parameters of drilling speed and life expectancy. Applications: Concrete, masonry, brick, anchors, fixings, hard concrete, green concrete, engineering brick
