Always get the 3 mode SDS drills. I have a corded Bosch with the addon Drill chuck. Makes a good mud mixer, heavy duty drill, scrapper, chipper and concrete drill all in one
Hammer/chipping-only mode is in the 6 o'clock position on this model. (There are a couple of other models in the dewalt lineup that don't have hammer mode, but this one does.) For those interested, there are some pretty comprehensive reviews & testing of this model on Boltah Downunder's channel.
Why push it the reason it's SDS is you just NEED to hold it in place and it will do it's thing. Does nobody understand how these tools work. FRUSTRATING. Oh and it does have a hammer mode only look carefully and read manual.
