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: Great high quality tool! - By far the tool I use most. More than enough torque to do most jobs. Small and light enough to get into tight spaces and not be tiring when using for several hours. I like the different heads, makes switching between drilling and driving really fast. Trigger and ergonomics really well done, great if you have kids you want to get into woodworking

A: The same motor different bodies.

**Q: Where is this made from?**

**Q: What is the maximum drill bit size for the keyless chuck?**
A: It's a 3/8" chuck. It'll even chuck up 1/2" bits with a reduced shank. If you're using spade bits, I've used it with up to 1 3/8", on low speed

**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.

### ⭐⭐⭐⭐⭐ Handy drill - good quality so far.
*by Z***P on December 14, 2025*

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.
