Dewalt quality drill bits

This is a quality drill set. The bits are sharp and cut into the material without issues. The case holds the bits in securely but easy to take out when pulling it out from the top. It does have extra space to have small parts to fit in the box, I tend to throw screws and such in the case. The case also has little gaps to allow holding drill bits being used when switching between bits. The case also was designed to be modular so it can hook on other cased if stacked.

Great price for drill bits if they work

I have high hopes for these because in my DeWalt drill it doesn't hold drill bits very well like most DeWalt drills. I'm thinking the flat spots on these may make the difference and be a game changer. But I also did change the checkout on my old 18 volt DeWalt drill for 20 bucks instead of buying a new one for 140 bucks so I'm crossing my fingers on both playing fields. I really like my Milwaukee black drill bits that come in the little red box those have been super sharp and go about through anything but that doesn't help when I use them in my yellow DeWalt drill. But I have high hopes for these and I hope they work out really great and keep an edge

Good quality

Good quality drillers. Used mainly to drill in metal. I use them to drill in wood as well even though they are not ideal for it. Cannot be use for concrete.
