Great drill! Feels good in hand. Great power and control with adjustable speed trigger. The weight is ok but I don't think I would want anything heavier. The cartridge is easy to put on, nothing slips in it. All in all a great tool.
Pros
Flexible power system - both DD and HDD are compatible with any Bosch 18V Li-Ion battery
This drill is amazing. And the case is great, the precisely fitting shelf is perfect and keeps the tool safe in the box. This drill has enormous torque and is very heavy. I hope for many years of service from this tool. I recommend it to anyone looking for a great tool.
Pros
New patented gear train and clutch - most compact design in its class and lightest weight
Really like this drill. You can't go wrong with Bosch, but this one is particularly popular. I love the LBoxx series and love the drills even more. Use it for Demarcs assembly, drilling cable/conduit holes and general demolition work. Bosch has done a good job here. The only downside is that it doesn't come with an extra handle (2602025158) but instead for <$20 on the Bosch parts page - done!
