The Milwaukee M12 H is a 12v cordless SDS drill. I bought mine from ebay- https://fave.co/2YFbbp8 This drill is very light and compact and can power it’s way through the toughest of masonry. The maximum diameter drill diameter for masonry is 13mm. I’ve owned this drill for about 5 years and it is now my drill of choice when installing fixings, such as wall plugs, or concrete anchors etc. Because the Milwaukee M12H is so light, it is really easy to use with one hand, when working at height etc.
