Bought a Bosch Drill. Chuck packed up after five months. Mega Mica Eastgate say chuck not covered?? Bought 2015/12/19 08:57:22 for R2999.00

Not much can be done if the dealer will not warrant the chuck
if the bosch name appears on the chuck, call bosch direct and make a complaint but if it doesn't then get a new and better quality chuck and replace the chuck on the drill
remember that ordinary key operated 3 jaw chucks are not designed to used in a hammer operation continuously as that damages the screw mechanism of the chuck especially if the drill bit is over 5/16 drill size
if that is your operation, invest in a special masonry drill such as ramset or hilti or other makes of that sort
