BOSCH GSB18V-45 18v Brushless Combi Drill with 1x6ah Battery

When choosing a Cordless Combi Drill, one of the key aspects is identifying how you are going to use the tool. It’s easy to buy more tool than you really need. Look at the torque offered by the product – the larger the torque, the more turning force your tool will have.
Modern Cordless Combi Drills bring plenty of power to your work and offer lightweight portability, meaning that whether you’re on site or working around your home, you and your Combi Drill can go wherever you need to.

Cordless Combi Drills are ‘all-rounders’; they have screwdriving, drilling and hammer drilling modes. You’d typically switch between them using the collar of the drill. Screwdriving mode allows you to set the amount of torque you want to apply to the screws you’re tightening or loosening. The standard drilling mode will help you make holes in wood, plastic or metal, while the hammer drilling mode is great for penetrating brick or concrete.

Drill Drivers are designed for driving screws and drilling holes, so are brilliant for lots of jobs but struggle to penetrate the toughest material). Because they have a hammer drilling function, Combi Drills can penetrate brick, concrete and similar materials in a way that a Drill Driver wouldn’t be able to.

Brushed motors use carbon brushes to transfer power from the fixed part of the motor to the rotor. This creates a reliable and relatively inexpensive motor, but brushed motors do require regular maintenance, in order to either clean the brushes or replace them as they wear out. A brushless motor, by contrast, uses a magnet mounted on the rotor to generate the power and electrical switching to perform the function carried out by the brushes. The additional complexity of the motor’s working means that brushless motors are usually more expensive than brushed.
However, eliminating the brushes also eliminates internal friction and maintenance, meaning that brushless motors offer both increased power and a longer working life. Brushless motors also generate less heat and noise and so, on balance, are considered superior to brushed motors.

Our range of Cordless Combi Drills starts with 12v machines, but the increased power and relative affordability of 18v tools means this has become the industry standard. Professionals who need more power from their Combi Drill for working on site could also consider the 40v XGT range from Makita.
