There's always some level of nervousness when drilling into tiles. Bosch – like you – want this process to be as quick and painless as possible. That’s why the brand is offering a solid selection of Expert Ceramic Tile Drill Bits. For this test, The Tradie met up with carpentry apprentice Angus Redfearn from Teak Building Co in Melbourne.
