I was very pleased with the quality of the bits in this set. Equally impressive was the beautifully crafted case that fits into a previously empty slot in my Milwaukee 2410-22 M12 case! So many drill and screwdriver sets from other well-known brands come in a cheap case that breaks within weeks of purchase, but this one doesn't have those problems! Sturdy body with rubber bumpers on the ends and a very simple but effective locking mechanism. I also love the fact that the bits stick out of the holes in the holders instead of being held by those annoying clamp holders that end up hurting your fingers trying to get something out, or worse, one of the little bits breaking into the half in progress! If you're looking for a quality drill set to complement your drill/screwdriver, you won't find a better choice than this! While these bits will work with any brand of drill, if you don't already have a Milwaukee cordless drill, this bit set will give you an idea of the quality this brand offers. Your cordless drills are even more impressive than drill sets!
