When looking for the right hammer drill, you have to consider a few things before you make that purchase. First you have to take a very close look at its power system. How many speeds does it have? What about its torque? How many rotations per minute can it do? What is its housing made of? How durable does it look in terms of construction, features and price?
You would also need to know if what you want to have is a corded hammer drill or a cordless hammer drill. Where are you going to use it and what is it most likely going to be used for? Would you be needing to take it along with you as part of your job or is it just going to be used in and around the house? What about the chuck? How easy and fast would it be to change bits at one time? How about the handle grip, is it built for comfort and balance? Would it give you maximum control over what you are doing?
If it is a cordless hammer drill that you are after, make sure that you get every information that you can about the battery before you buy it. What is its battery made of, NiCad or Li-Ion? While some units may be cheaper if it’s a NiCad that it comes with, the battery life may not be as reliable compared to Lithium-Ion. Li-Ion lasts so much longer, and charges so much faster. Some units also come with just one battery with no replacement. Look for the one that will provide you with an extra battery so you can efficiently charge one while you are busy using the other. In that way, you are assured that there will be no chances of you running out while in the middle of a tough job.
There are also some hammer drills that come with a built-in LED light that would conveniently provide illumination if you’re working in enclosed spaces or if you’re in the dark. Also, make sure that your unit is backed by a warranty against defects. These powertools do not exactly come in cheap all the time so make sure that you are left with an assurance that you’re not throwing away money just like that.
There you are folks. Just a few guidelines in choosing the right hammer drill. Be smart enough to know what you’re purchasing and you are guaranteed that it will last a whole lot longer than you think. Good luck and happy drilling!
