The Makita DHR171Z is a lightweight drill with excellent SDS drilling qualities, the low rotational speed of just 680rpm is combined with a high 4800 impact blows per minute giving the drill amazing drilling power, holes are drilled in concrete in a fraction of time compared to other drills that are just starting to make an impression.
This drill bought for use off ladders or at height where one is unable to apply pressure against the drill bit, the Makita does not need any force to be applied the drill cuts a hole in seconds without the normal bounce due to the high impact rate and slow turning speed, this allows the SDS bits to work as intended and at their best.
The drill is lightweight at just 1.6Kg so can be used one handed, ideal for ladder work, the DHR171Z is just an SDS drill and cannot chisel or stop rotation, it is designed for one purpose that it excels at, SDS drilling.
This thing is amazing. I've been making heavy use of it since I bought it and it never complains. Lightweight and powerful.
Better drill than my Bosch 36volt drill
Fantastic
Seems underpowered when you pull the trigger but once you’re drilling it is excellent, powerful & even with 4AaH batteries it does loads of holes.
Worth the money
Very light and great ergonomics ,a bit dissapointed with drilling perfomace ok for brickwork but very slow drilling concrete
