The brand’s idents were created by V4 and will promote the different products it has for DIYers.
The idents will run twice an hour, all day, across shows including Salvage Hunters, Combat Dealers, Mighty Planes and I Am Steve McQueen. There will also be pre-roll on Quest OD, its video on-demand platform.
Martin Heaton-Cooper, the vice-president of commercial development for UK, Ireland & International advertising sales EMEA at Discovery Networks, said: "Quest is one of the fastest growing TV channels in free-to-air and has grown by another 21 per cent in Q1 versus last year as it continues to build its loyal fan base.
"A brace of firsts for Quest and Bosch Power Tools sees a smart, multi-platform campaign run across live TV and on demand content."
The six-figure deal was struck by OMD and begins on 1 May for six months.
Joao Barufi, the brand director at Bosch, said: "We are delighted to be the first channel sponsor for Quest. We pride ourselves on our reputation for reliability and we wanted to bring this to life through our latest advertising campaign.
"We hope these idents will raise awareness amongst new customers while also reminding existing users of the benefits of choosing Bosch for their home DIY and garden projects."
