Some manufacturers engineer safety checks into the motor and battery of their tools. So, keep your eye out for the safety features installed on the drill. Keep reading to find out our top recommendations for best SDS hammer drill.Ĭlearly, the type of applications you’ll be performing with your cordless SDS+ hammer drill will take a toll on the tool and you. Our guide will cite the weight of the drills with the battery attached. 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. The advent of brushless motors has seen more smaller sized SDS+ hammer drills appear on the market which give the grunt you’ll need. 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. 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. 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. The harder the drill works, the more charge the motor will need to pull from the battery. 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.īearing all of this in mind do you need portability or do you need heavy hitting? The higher the number the stronger the impact. 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.Īnd very importantly, look out for the Joules, or energy, behind each BPM. Make sure to be on the lookout for the blows per minute (bpm) and revolutions per minutes (rpm). Now you’ll be able to use all of your standard drill bits. 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. The final type of SDS+ hammer drill available, determined by the modes offered, is the 3-mode with changeable chuck. What features should you look for in a cordless SDS plus hammer drill? LOOK FOR 3 MODES! An SDS hammer drill will allow you to drill into wood, metal and masonry with ease. 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. Hammer action, coupled with the SDS+ bit, means you get the job done with little effort needed. There are 3 types of SDS drill: Regular SDS drills, SDS Plus drills and SDS Max drills.Įnergy is delivered to the bit in a much more efficient way, reducing the amount of pressure the operator needs to put into the application. This makes them highly effective at drilling in the toughest materials like concrete and masonry that standard drills simply could not handle. 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.Īn SDS drill combines the hammer action of a hammer drill with the rotary motion of a regular drill. This design allows them to be inserted into the chuck with a twist and locked into place via the chuck’s sprung ball bearings. Some argue that it comes from the German phrase ‘steck, dreh, sitzt’ that translates as ‘insert, twist, fits’.Įither way, SDS+ refers to how the chuck interacts with the bit. There are a few definitions of the term, the most common of which is “Slotted Drive System”. First off, we need to understand what SDS+ means.
