Questions and answers
- Which is better for drilling concrete?
- The 2904-20. It has a hammer mode and 1,400 in-lbs of torque. The combo kit's drill is a drill/driver with no hammer function.
- Is the combo kit worth it if I have no M18 batteries?
- Yes. It includes two batteries, a charger and a bag, and its recent low of $149.99 was below the $159.99 bare-tool price of the 2904-20.
- Which has more torque?
- The 2904-20 drill at 1,400 in-lbs beats the kit's 550 in-lbs drill. The kit's impact driver delivers 1,700 in-lbs, but that is driving torque, not drilling torque.
- Do both use the same batteries?
- Yes. Both run on M18 18V REDLITHIUM packs, so batteries and chargers are shared across the platform.
- Which is better for overhead or tight-space work?
- The combo kit. Its drill is 5.7 in long and its impact driver 4.4 in, against 6.9 in for the 2904-20.
- Is the 2904-20 worth the extra money?
- Only if you need hammer drilling or maximum drilling power and already own M18 batteries. Otherwise the kit gives you more tools and power sources for less.
