The DeWalt. Its DCD1007 hammer drill has a hammer mode and 2,100 in-lbs of torque. The Bosch has no hammer function and 400 in-lbs, so it is for wood, metal and drywall.

Do I need the impact driver?

If you drive lots of long screws or lag bolts, yes. The DeWalt's DCF845 delivers up to 1,825 in-lbs and 3,400 RPM. The Bosch drill/driver covers light fastening with its 20+1 clutch.

Which is easier to use all day?

The Bosch. It weighs about 2.4 lb and is 6.3 to 7.44 in long. The DeWalt kit weighs 13.73 lb with both tools, batteries, charger and bag.

Which lasts longer per charge?

The DeWalt, on paper. It ships with a 4Ah and an 8Ah battery, and DeWalt rates up to 275 holes per charge with the 8Ah in fir. The Bosch kit has one 2Ah (36 Wh) battery.

Is the DeWalt worth the extra money?

It is $299.00 at The Home Depot as of November 3, 2026, for two tools and two batteries. That is good value if you need hammer drilling and an impact driver. For light home drilling, the Bosch is the simpler buy.

Can the Bosch handle deck building?
