Perfect for DIY Projects – My husband loves It!
I got this set for my husband, and he absolutely loves it. We do a lot of DIY projects around the house, so we were looking for something versatile and durable — this DEWALT set definitely stood out. The variety of bits is perfect for handling different screw types, which makes it super convenient whether we're working on furniture, shelving, or quick fixes. I also really appreciate the tough, compact carrying case. Everything stays organized and secure, so we’re not constantly losing bits around the house. It’s a solid, well-made set, exactly what we needed. Highly recommend for anyone who does regular home projects or just wants a reliable screwdriver bit set on hand.

Very nice set.
I love these! My old set was missing several bits so it’s nice to have a full set. I also purchased the drill bits and was pleased to find out the two cases stack together. Looks like they have everything I need for projects around the home.

Excellent Quality Bit Set!
This bit set has exceeded my expectations. Every piece feels solid and well-crafted, with no cheap or flimsy parts. The bits fit perfectly and grip securely, making work so much easier and more precise. I’ve used them on a variety of projects — from assembling furniture to small repairs — and they’ve held up beautifully without stripping or wearing down. The set comes in a well-organized case that keeps everything in place, and the range of sizes and types means I’m always prepared for any job. A must-have for anyone who likes to be ready for quick fixes or serious projects.

Good and Bad...
I am replacing some stolen items and my original purchase, Bauer, from Harbor Freight is no longer available, so thought I'd try something new. I bought the DeWalt Drill set, which was fine, and then decided to by the matching DeWalt Bit set... The tool cases are hard see-through plastic (for no real reason and poorly designed for many other reasons) and if you drop it or drop something on it, it's going to shatter. The latches protrude above the top cover to allow for stacking (they do stack nice) but if they get pushed around in a tool bag or case, something could catch the latch and the case could open up and the lid could be broken off... not going to try it to find out. The sockets that hold the bits are very tight and the rows do not rotate up for easy extraction. I do not have FAT heavily callused fingers and it's even difficult for me to remove and reset the bits. you can move the bit rows around and they could have even added 1 or 2 extra rows for personal bit selection. I was also rather disappointed in their bit selection as it was rather limited and may be a "standard" contractor type use, in that it had 14 P2 Philips (What are you guys do?... lol...) and 6 SO2 Square tip... and several duplicates of other... I went into my parts boxes and dug out a wider range of bits to give me a full set. As I'm not a working contractor "out on some work site" I don't have to worry about breaking a bit and not having 13 back-ups... I just go to my parts drawer when I need one. Not that it's a specific issue, but when fully loaded, both the drill and the bit box weigh over 1.2lbs... don't drop them on a hard surface... especially if you have 2 or more stacked together... but they do stack nicely, which is about the only good think I found, other than that the bits and drills do appear to be decent quality, but I would have expected that.
