MAKITA B-57629 SDS-MAX Concrete Core Cutter Drill Bit 40 x 550 mm

Concrete core bit, concrete drill bit MAKITA B-57629 for masonry drilling SDS-MAX size 40 x 550 mm
Specifications MAKITA B-57629 is a drill bit used for rotary hammers that operate with simultaneous hammering and rotation. This drill bit comes with an SDS-MAX shank system, Makita's largest and most durable shank, to transmit maximum impact energy and torque in hard material drilling applications.The 40 mm size provides a very large drilling diameter, while the 550 mm overall length is ideal for drilling large openings for pipe feedthroughs or installing structural fixtures through multi-layer thick walls or concrete floors. The bit features tungsten carbide cutting tips offering exceptional hardness, along with flutes engineered to evacuate rock chips and dust efficiently and rapidly.
