About this product
This Faithfull SDS Plus masonry drill bit measures 20mm in diameter, with an overall length of 410mm and a working length of 350mm. Its extra-deep drilling capability suits large-diameter applications such as thick masonry sections, deep foundation work and heavy-duty anchor or pipework installations.
The bit has a heavy-duty tungsten carbide tip and fits SDS Plus chucks, giving a secure, non-slip grip for maximum power transmission during rotary percussion drilling. It is suitable for bricks, blocks, concrete containing aggregates, marble and other hard stone or masonry materials.
The fluted shaft design helps transmit power efficiently and prevents a worn shank from making an otherwise usable cutting edge redundant. The SDS Plus fitment also allows quick changing of drills using a keyless chuck.
