Review: You NEED This - Pro user here. I own a home services company. This is an amazing tool. For most regular tasks it has ample power. I love the soft start when trigger is pulled and the different drill accessories are incredibly useful. ULTRA quie, too. Easy to change heads for different tasks and small but very solid feeling...not light and plasticy junky feeling. Great for lighter drilling and driving. I have bigger, stronger drills and impact drivers for the heavy duty tasks. My hands are a little arthritic now and this little guy allows me to do more without resting (removed 30 outlet and switch covers for a painting job at twice the speed of normal). I wish it had a better quality case that had moulded areas for each accessory head to keep everything in place, but that is a minor gripe. Just bought a second set for my other business! BUY it. You won't regret it. I may need to buy a 3rd one for my son's tool kit (he's 10). Hope this was helpful!
Review: Handy drill - good quality so far. - I like the different adapters on this drill - I don't need them often but when you do, they really make a project go more smoothly/easily. Good quality. Battery life is ok for a "hobby use" which is my use case. The batteries come in larger capacity and I'd probably get a 4 ah if I were doing professional work. I've got 2 smallest batteries that are light which is my preference. The storage case is "ok" but not using it that much to be honest. It has decent torque. My milwaukee M12 drill is probably a bit more powerful but not something that matters much - I am more interested in the flexibilty of the attachments. The right angle one is my favorite. Used that several times and it saved the day. I'd buy it again.

**Q: Electric 110 or 220**
A: The Bosch Power Tools in North America are all 110/120V power rating. If you will use this on 220/240V, you will need to get a power converter to step down the voltage that you have in your area. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

### ⭐⭐⭐⭐⭐ Great all around drill that will last
*by S***T on January 16, 2026*

This has become my go-to drill for just about any house project, it's compact and light weight, the LED on the front illuminates whatever you are doing, and its very powerful for the size. Paired with the Bosch screw and drill bits, (which can fit with all the attachments in the included carrying case) makes changing bits very fast. I have owned for over 6 years and had no issues with this set, both of the included batteries still work great and hold charges (even without use) for months so its always ready to use. Just bought a second one for my parents as their old heavy drills were becoming hard for them to use.
