The settings of a Hammer of a corded drill is measured in blows per Minutes (BPM). It is primarily used for drilling through concrete, bricks, stone etc. according to an article on the Tools Inside blog, a big mistake that many drill users make is to permanently leave this hammer function on. Just ensure that you never do that as you should not be drilling through wood or any form of metal with a hammer function.
User Comfort & Ergonomics
Many manufacturers make a big play on this. Any drill should feel well balanced, and be light enough not to cause user fatigue along with a neat grip
The crucial question to ask and the things to watch out for are; does it come with a side handle, as that can be really useful for some drilling? Users also want the choice of being able to keep drilling without always having to hold the trigger down.
If it has all that, then most users are pretty content and tend to then ignore all the sale’s waffle and blurbs. So in very simple terms a side handle and a lock button for the trigger are a really useful feature to have.
So many people look for a reverse function in a drill. With a corded drill, except you are trying to use it with a driver set, then there’s a point in having this feature. This type of drill is useful for drilling holes and what is the point in having a reverse on that.
Corded drills are not actually designed to be used as screwdriver or impact drivers, though some can be used for that purpose. They are not really the tools for those type of jobs though, so not something I would look for myself.
So those are the main features examined and hopefully, that has really helped.
