About this product
This Faithfull SDS Plus masonry drill bit measures 4mm in diameter, with an overall length of 160mm and a working length of 100mm. The smaller diameter suits pilot holes, small fixings and delicate installation work where precision is needed, while the length allows standard-depth drilling without loss of accuracy.
The bit is tungsten carbide tipped for a durable cutting edge and fits SDS Plus chucks, giving a secure, non-slip grip that transmits power efficiently during rotary percussion drilling. The fluted shaft aids power transmission and helps avoid a worn shank rendering the cutting edge useless, while the SDS Plus fitting allows quick changing via a keyless chuck.
Suitable for use in bricks, blocks, concrete (including aggregates), marble, hard stone and other masonry materials.
