Anything for grown ups or only this toy one? 15Nm - forget it!
This drill doesn't have hammer function. Are you talking about 100mm hole? You need corded drill Something like this https://www.hotukdeals.com/deals/bosch-professional-gsb13re-corded-240-v-impact-drill-ps3887-at-amazon-france-uk-mainland-3838920?utm_source=mappshare&utm_medium=referral&utm_content=3838920&utm_campaign=2021-11-28 It might last you lifetime.
Can anyone recommend a cheap drill like this that will be good enough to drill into brickwork to put a tumble dryer vent on?
Better to get something like this. Its more expensive but at least last longer and extra battery and hammer mode for light duty. https://www.amazon.co.uk/gp/product/B01N4PT3ST?tag=pepperegc-21&ascsubtag=2270593056
15nm torque and 650rpm are awful specs. You'd expect at least double that even from a budget cordless drill. For general DIY I'd recommend 35/40nm plus.
