Product Description These high performance Faithfull Tungsten Carbide tipped drill bits fit into 'SDS-plus' chucks which provide a particularly secure non-slip grip that transmits maximum power for rotary percussion drilling, mainly into concrete. The SDS-plus bits ensure maximum power transmission due to their unique fluted shaft. This effectively removes situations where a perfectly serviceable cutting edge is rendered useless by a worn shank. The SDS-plus system also enables faster changing of drills using a quick release keyless chuck. For use in bricks, blocks, concrete containing aggregates, marble and hard stone and other hard masonry materials.
