About this product
The Faithfull FAIMAX20520 is a 20mm diameter SDS Max masonry drill bit with an overall length of 520mm and a working length of 400mm. The extended length gives capacity for deep drilling in large-diameter applications, such as deep anchor points in structural concrete, thick wall penetration and long fixings in masonry.
The SDS Max shank fits any machine with an SDS Max chuck, providing a secure connection with no slippage during use. An L-shaped flute profile aids dust extraction, and the bit is suited to concrete and brick applications.
