Both the original links are poor. That dewalt has a ni cd battery for starters ,
As above sds for concrete.
Look at hitachi
used their cordless 24v sds and their impact driver and combi drills , all seemed good to me and have stood up to my dads abuse for a number of years . The dewalt he replaced the drill driver with ( after he dropped hitachi a fair height) is lighter for swinging about every day though.
Ive got their nail guns , circ saw and brushcutter and having used paslodes , makita and stihl on a daily basis growing up working for my dad and grandad i have no qualms recomending their kit.
