What to check before buying a Bosch combi drill
Bosch offers two main lines: the blue Professional series for trades and the green DIY range. Professional models use the 18V ProCore battery system for higher runtime and power. Key specs to compare include torque (Nm), impact energy for masonry, and chuck quality. A brushless motor is worth the extra cost for longer life and better efficiency.
Mistakes to avoid
Do not buy a green Bosch for daily professional use the battery system is less robust. Avoid corded models unless you need maximum sustained power for drilling into concrete. Do not ignore the weight of the drill heavier models with higher torque can cause fatigue during overhead work.
