How do drills work?
An electric drill converts electricity into mechanical energy (in the rotating drill bit) using an electric motor. As the drill bit bites into the material you’re drilling, the mechanical energy is converted into heat energy.
Is a 20V drill better than 12V?
Some cordless tools require more power than others. Tasks that use more torque need batteries with a higher voltage to complete the toughest jobs. That’s why many craftsmen choose to use the 20V MAX* instead of the 12V battery for the toughest jobs: higher voltage generates more torque.
What is the difference between an 18V drill and a 20V drill?
It’s because an 18V battery can charge up to 20V just like a 10.8V can be charged up to 12V (in the case of lithium batteries). This means that the MAX refers to the maximum voltage the battery can store as opposed to the 18V that refers to the nominal voltage of the battery cells added up.
Do Impact drivers have torque settings?
Impact drivers do not have torque control, so the only way to adjust the amount of torque being delivered is by using the speed control trigger (or by selecting a model with several gears). These tools are extremely powerful, producing up to 150Nm of torque!

The main difference between a drill and an impact driver boils down to power and rotational action. Unlike drills, impact drivers have quick release shanks that accept all one-quarter inch hex driver bits. Internal mechanisms allow impact drivers to produce more torque than drills, and in quick bursts.
Should I get a 12V or 18V drill?
It’s obvious 18-volt tools are more powerful than their 12-volt brethren, but 12V vs 18V isn’t just about power. You simply may not need all that torque. However, if you are in production where you’re doing heavy-duty, high-stress tasks, then an 18-volt platform is better suited for the job.
