Are you having a hard time deciding what is the best cordless SDS hammer drill for your specific needs? Heck maybe it’s not even worth picking up cordless and picking up a corded hammer drill will work best for you! In this post I want to help you to make a better educated decision before you purchase the wrong SDS hammer drill all together.
It really wasn’t that long ago that using any kind of cordless tools for concrete was unheard of. Lets face it, concrete is one of the most unforgiving building materials out there and honestly it takes some brute force and energy to drill through it. But fortunate for us, new advancements in technology are always being introduced including Lithium Ion Batteries which have changed the game of cordless tools all together.
If you just want a great all around Cordless Rotary Hammer, we recommend this one (amazon link), it’s the one we would choose if we could only pick one!
Advantages and Disadvantages Of A Cordless SDS Hammer Drill
Before we get into choosing the best cordless SDS hammer drill I would like to take a moment and actually break down some of the advantages and disadvantages of going cordless over corded. Now I’m sure you probably already know them but I like to cover all of the bases in my articles so bare with me.
- Versatility – Of course one of the first advantages is versatility, without having to worry about power and cords you are free to use your hammer drill anyway, anytime and anywhere you need it
- Fast & Convenient – There is really nothing worse than always having to run around with extension cords trying to find the nearest power source, especially if you are only drilling a handful of holes. With a cordless drill all you need to do is grab and go, easy as that
- Battery Life – This is of course one of the biggest disadvantages of a cordless SDS drill. Especially if you are on a bigger job where you need to drill lots of holes, in this case maybe cordless is not the best option.
- Lack Of Power – Honestly in my experience this usually only stands true when you start comparing cordless to larger corded SDS drills. In fact when it comes to BPM’s, RPM’s and often times Impact Energy in similar models they are very comparable. In fact lets look at a side by comparison of the Bosch RH328VC and the RH328VC-36K
Choosing The Right Cordless SDS Hammer Drill For The Job
As I have mentioned many times on this site there is absolutely nothing worse than coming up too short when it comes to dealing with concrete but at the same time you don’t want to show up with too much artillery either. Let’s have a look at a few things that you should consider when choosing the right cordless hammer drill.
- Hole Diameter – The first thing that you should probably consider before rushing out and purchasing a drill is the size of hole that you plan on drilling. Each size of drill is specifically designed to drill a set diameter of holes efficiently.
- SDS Plus is designed to perform best from 3/16” to 3/4”
- SDS Max is designed to perform best from ½” to 1 ¾”
- Spline is designed to perform best from ⅜” to 1 ⅜”
- Operation Modes – What exactly do you plan on using your new cordless SDS drill for. Is it solely for drilling holes in concrete, brick, mortar etc. or do you plan to be able to use it as a chisel to bust up tile, concrete or brick? Not every SDS hammer drill is created equally, some offer 2 mode operation (drill only & hammer drill) and others will offer 3 mode operation (drill only, hammer drill & hammer only)
- Battery Type – It goes without saying nowadays, if it’s not Lithium Ion then it is probably not worth your time unless you have a plethora of spare batteries charged and ready to go. But even when it comes to Lithium there are a few different types to consider depending on what your needs are. Here are some of the most common battery types you will find in cordless rotary hammers
- 36 Volt or 18 Volt – Naturally the 36V option is going to offer you more punch when it comes to smashing through concrete but an 18V is sufficient enough if you don’t plan to use it too much.
- Amperage Hours – When it comes to amp hours a 4Ah rotary hammer will last an average of 30% longer than the 3Ah but on the other hand a 4Ah battery can take up to twice as long to charge. So basically we’re talking about 6 of one and half a dozen of the other, what is more important to you, longer battery life or shorter charge time?
- Frequency Of Use – How often are you going to use your cordless SDS hammer drill? The reason I suggest considering this aspect is because unless you have a ton of cash to throw around then why pay top dollar for something that is going to sit in your garage collecting dust. Keep in mind though, a rotary hammer drill is a very useful tool for many different jobs around the home.
- Brand – As with anything that you can purchase nowadays there is always those brands that should not be playing with the big dogs. Sure you can save a little money by going with Nenz, GoPlus and even Ryobi just to name a few. The truth is, you are the one who will be paying in the long run. I suggest that you pick up one of the following brands of cordless sds drill, these guys are the big players in this game.
