purchased this item to reach the free delivery and because brick drill bits are always handy. Impressed by the quality (drilled a full brick as it was butter). Comes in clever size assortment being 6mm the one most used (4 pieces)

bought these for drilling porcelain floor tiles ,but each dill managed just one to two holes so used all 4 x 6mm drills to drill holes for bath side panel very poor at this price

For home or for work , amazing product .
