EXCLUSIVE! Milwaukee Quality Hex Bit Set! At home, I mostly use one of several small electric screwdrivers/drills kept in various places (household, kitchen, office, study, etc.) for those quick jobs that we all encounter and that only require one or more screws are. It's not uncommon for some of us to just need to drill a hole or two in something light (drywall, wood for a small project, etc.) and it's much quicker and easier to do it with just a hex-head fastener. Drill in one of these little electric drills/drivers. The problem I kept encountering was that if the screwdrivers had any hex bits, they were only 2-4 bits of poor quality. It seemed inevitable that the hole I needed to drill was a different size than the drill bits provided. So I decided I needed a much more complete set of hex shank drill bits! When trying to find a more complete set of hex shank drill bits, I was surprised by the small selection. And it turned out that most of the "kits" I could find were of poor quality, had very limited bit sizes, didn't have a security case, and/or were offered by brands I didn't recognize. limited it to what appeared to be just two high-quality sets: this set and DeWalt's 10-piece set. There was little price difference between them, so I was ultimately won over by the additional 8-bit sizes in this set, although I suspect DeWalt's "one-piece" design is arguably technically superior. So I'm basically betting that - for the light, low-rpm use I intend for these bits - the difference in design doesn't matter. Exceeded or met my expectations.
