Specifications MAKITA B-57700 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 80 mm size provides a very large hole diameter, while the total length of 990 mm makes this drill bit ideal for drilling extra-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.
