We’ll look at the best cordless SDS drills in this section. We’ve compared efficiency, quality construction, ease of use, and cost to send you our best suggestions.
The Makita DHR280ZJ Twin 18v SDS+ Rotary Hammer has XPT – Xtreme Protect Technology which is optimum protection against dust and splashes water even under harsh conditions. Brushless motors are more efficient than a brushed motor meaning more run time. Less heat produced making them more suitable for prolonged use.
SDS Plus accepts a 10mm diameter shank (the part of the drill bit that attaches to the chuck) and is the most common type of SDS used. Designed for hammer drills up to 4kg, it is capable of handling the majority of building work needs and so has become the most common type.
Furthermore, we are pretty much going to be focusing here on SDS Plus drills only since they are the dominant type of impact drills on the market today and, in reality, unless you need the extra high drilling power for a specific job that an SDS Max drill affords, you are typically going to be buying an SDS Plus hammer drill.
What to look for in an SDS Hammer Drill
Cheap Muscle vs Refined Quality
In general, SDS Plus hammer drills fall into two broad categories, the less well-known, less expensive, fewer ‘bells & whistles’, and heavier drills (the Wolf, Silverline, and the Terratek), and the brand-name, more expensive, more universal, better-made, and lighter hammer drills.
The maximum revolutions per minute or RPMs that a drill can accomplish. It will be mainly determined by what sort of work the drill was designed for.
SDS hammer drills also tend to come with some common features too, such as multiple modes of operation. These days almost all hammer drills have the ability to switch off the rotary or the hammer action of the drill, typically providing the user with three modes of operation:
- Rotary action only (for drilling into wood, metal and plastics)
- Rotary hammer action (for hammer drilling into masonry, concrete and other hard materials)
- Hammer action only (for use as a power chisel)
Another common feature of hammer drills comes in the form of their safety characteristics. In the interests of user safety, and since today’s hammer drills generate. Such high levels of torque, corded SDS hammer drills almost always include a slip-clutch or torque limiter. To prevent loss of control of the drill and potential user injury in the event of drill bit binding. The slip-clutch or torque limiter ‘detaches’ the rotary action of the drill bit from the drill motor if the drill bit jams in the substrate while drilling and thus prevents the whole drill rotating around the stuck drill bit potentially injuring the operator.
