To drill cordless, there are some fundamental features you have to understand. There are flexible drills that typically vary from low to mid-budget for drilling holes and driving screws. They're a popular choice and are sufficient for most tasks, including woodworking projects, or drilling in mild metal.
12-volt battery capacity is the main feature of the cordless drills. The maximum size of keyless chuck is generally up to bits 3/8", which is enough for most handyman jobs.
There are special cordless drills with much more torque and higher-rated batteries. A good illustration is a hammer drill joining a hammer and drilling action to produce holes in masonry and bricks. From my experience, there is nothing more frustrating than a powered cordless drill for this purpose.
Because these drills strategy the thousands weekly, they will need to be stronger for longer than ordinary drills. If you need a hammer drill to get larger jobs then don't compromise on the price because more costly batteries will function better in the long run.
The high-speed equipment (1200 rpm) will be for quicker drilling, and the reduced rate gear (400 rpm) to control the screwdriver jobs. Check whether the drill will rotate rapidly by squeezing the trigger, or by adjusting a round ring.
Can the drill have two batteries? In case you have to quit working to recharge the battery, then it can be frustrating not to get two batteries. This is a compelling reason to have two batteries to avoid downtime. Buy the best-rated battery you can manage since they will provide you the most efficient long-term service.
Do not ignore the way the cordless drill will sense as if you use it. For drilling and screwing little jobs around the house, weight or balance might not be significant. But before you purchase a massive drill, first check if you would feel comfortable carrying it for any length, particularly above your head.
