The DCH273B is lighter and has smoother and more graceful action , but it ’s still extremely efficient .
It also features an SDS chuck , which is German for “ steck , dreh , sitz , ” or for English speakers , “ insert , bend , stay . ” This type of eats is plebeian on rotary pounding drills , while steady drill drivers normally come with a stock three - jaw chuck . I found it comparable to a three - jaw chuck , but it does need special SDS bits .
