About this product
This Faithfull SDS Plus drill bit measures 12mm in diameter, with an overall length of 410mm and a working length of 350mm. Its extra-long design suits deep drilling into thick masonry sections, foundation work and other applications requiring extended reach.
The bit has a heavy-duty tungsten carbide tip and fits SDS Plus chucks, giving a secure, non-slip grip that transmits maximum power for rotary percussion drilling. The fluted shaft aids power transmission and helps prevent a worn shank from wasting a still-serviceable cutting edge, while the SDS Plus fitment allows quick changing via a keyless chuck.
Suitable for bricks, blocks, concrete containing aggregates, marble, hard stone and other hard masonry materials.
