This is a drill bit used with rotary hammers, operating with simultaneous hammering and rotary action. This drill bit comes with an SDS-MAX shank system, which is Makita's largest and most durable shank for transferring maximum impact force and torque in hard material drilling applications.The 65 mm size provides a very large hole diameter, while the total length of 990 mm makes this drill bit ideal for drilling large openings for running pipes or for installing large structures through thick multi-layered walls or thick concrete floors. The drill bit features a cutting tip made of tungsten carbide, which offers high strength, and flutes designed for efficient and fast debris and dust evacuation.
