Which is the Best Cordless SDS Drill?

Hitting hard and drilling big are important features of any SDS drill. Many of us are tethered to a power cord when we use our SDS hammer of choice, but in this Toolstop guide, we’ll show you why you should buy a cordless SDS+ hammer drill.

In this buying guide, we'll cover:

We’ve got a fantastic range of cordless SDS+ hammers in stock for next day delivery, click here to see what’s on offer.


What is an SDS Drill?

First off, we need to understand what SDS+ means. There are a few definitions of the term, the most common of which is “Slotted Drive System”. Some argue that it comes from the German phrase ‘steck, dreh, sitzt’ that translates as ‘insert, twist, fits’.

Either way, SDS+ refers to how the chuck interacts with the bit. SDS bits have a slotted shank. This design allows them to be inserted into the chuck with a twist and locked into place via the chuck’s sprung ball bearings. This pays dividends when the drill is used in hammer mode as the slots in the bit allow for the back-and-forth action required while reducing friction within the drill.

An SDS drill combines the hammer action of a hammer drill with the rotary motion of a regular drill. This makes them highly effective at drilling in the toughest materials like concrete and masonry that standard drills simply could not handle. There are 3 types of SDS drill: Regular SDS drills, SDS Plus drills and SDS Max drills.

Benefits of SDS drill bits

Energy is delivered to the bit in a much more efficient way, reducing the amount of pressure the operator needs to put into the application. Hammer action, coupled with the SDS+ bit, means you get the job done with little effort needed.

The SDS drill combines hammer action from hammer drills with the rotary motion of a regular drill to give them the power and functionality needed to complete heavy-duty tasks. An SDS hammer drill will allow you to drill into wood, metal and masonry with ease.

What features should an SDS Hammer have?

Think Modes, BPM, Joules and RPM! SDS+ hammer drills are available in a few different varieties, determined by the modes. SDS drills typically come with either 2 or 3 modes, as explained below.

A 2-mode SDS+ hammer drill will have rotary hammer and rotary only modes. You’ll be able to drill into wood or metal (using rotary only) and by selecting the rotary hammer mode you’ll also be able to drill into masonry thanks to the hammer-action.

A 3-mode SDS+ hammer drill gives you the same functions as a 2-mode SDS Drill, but with the added addition of chiselling function. This is the ideal drill for some light chiselling or chipping into concrete or masonry.

Often a 3-mode SDS+ hammer drill will include a neutral position on the mode selector which gives you the opportunity to position your chiselling bit at the desired angle, before moving the selector ring to chisel mode.

For the most demanding tasks, you would typically opt for a 3 mode SDS drill.

What features should you look for in a cordless SDS plus hammer drill? LOOK FOR 3 MODES!

The final type of SDS+ hammer drill available, determined by the modes offered, is the 3-mode with changeable chuck.

This type of SDS hammer gives you the benefits of a 3-mode but also allows you to swap out the SDS+ chuck for a regular chuck. Now you’ll be able to use all of your standard drill bits.

Make sure to be on the lookout for the blows per minute (bpm) and revolutions per minutes (rpm). In each case the higher the number will typically be better in terms of how hard the drill will chisel or drill into masonry and the size of holes you’ll be able to drill.

And very importantly, look out for the Joules, or energy, behind each BPM. The higher the number the stronger the impact. Obviously, a smaller machine will give you all the benefits of a lightweight drill such as superior ergonomics and a less-fatiguing experience, but it may lack the energy to punch as hard as one of its larger relatives.

Bearing all of this in mind; do you need portability or do you need heavy hitting?

Features to look out for - Portability or big hitting power?

The harder the drill works, the more charge the motor will need to pull from the battery. So if tougher applications are your norm, you’re going to be in the market for a tool that comes supplied with higher capacity batteries, such as 4.0Ah or higher.

In summary then, determine the type of applications you’ll perform most with your cordless SDS+ hammer drill, then make a buying decision based on the number of modes you’ll require.

Think Size and Weight - Just because an SDS+ hammer drill has been designed for pushing larger bits into harder materials doesn’t mean that the drill itself needs to be large and weighty.

The advent of brushless motors has seen more smaller sized SDS+ hammer drills appear on the market which give the grunt you’ll need. Therefore, even though the addition of a battery adds a little weight to these drills, going for a brushless model will claim some of that weight gain back in your favour, meaning you can use the drill for longer periods without arm or hand fatigue.

Our guide will cite the weight of the drills with the battery attached. Keep reading to find out our top recommendations for best SDS hammer drill.

Think Safety!

Clearly, the type of applications you’ll be performing with your cordless SDS+ hammer drill will take a toll on the tool and you. So, keep your eye out for the safety features installed on the drill.

Some manufacturers engineer safety checks into the motor and battery of their tools. These are great ways to make sure you’re not overloading the drill and putting yourself, those around you, and the tool itself at risk. Therefore, check the spec of your new cordless SDS+ hammer drill for any safety features like an electric brake built-in.

Should You Buy a Body-Only Cordless SDS+ Hammer Drill?

Sometimes it’s possible to buy a cordless power tool like an SDS+ hammer without batteries. This is called “naked” or “body only” (click for our guide to this type of tool). If you’re already carrying around spare batteries that are compatible with the SDS+ hammer drill from your manufacturer of choice, it might save you cash opting for the naked version.

Alternatively, look out for the SDS+ hammers that are supplied with higher capacity batteries. Higher capacity means longer runtimes, it’s that simple. And if your cordless SDS+ hammer is sold with more than one battery, that could be a huge advantage to you also.
