Rated 5 out of 5 by from Bosch Drill Bit Excellent quality drill bit, proof being we accidentally found these were much faster at drilling porcelain tiles than tile bits costing many times more! Will only buy these from now on...

Rated 5 out of 5 by from Super Drill Bits These drill bits are great, these are all I purchase now after trying them out. I use the 4mm one to Pre drill porcelain tiles and then use another multi drill bit for the size of plug and screw I'm going to use to fix with. keep them cool and will last for longer. They also drill through ceramic tiles like hot knife through butter, no need to use the drill on hammer either. Definitely reccomend
