Though generally I'll say that one should always go somewhere other than HF for tools, the truth is every once in a while they have a great product.
Couple of years ago, I erected a large metal building. There was the need to drill many thousands of small holes. At just the right time HF sent me a flyer with a listing basically for the sized bit I needed, bag of 50 for about $10. I figured what the heck, I'd only loose $20 so I ordered two packs (that gave me 200 bits, since these were double ended!)
Well, the building is up. One pack is still unopened. The other pack is almost full. Some of the bits that I used when I first started are still being used now, the only ones that failed were ones that I broke! Some of the blasted best drill bits I've ever bought, and I paid a couple of pennies for each one. Heck, at this rate I'll die and still not have opened that second pack... (And I use a lot of drill bits, too.)
But, bottom line, usually one gets what one pays for. Buy cheap, get cheap. My HF Rayobi 18V drills... (Got to do the building too) were intended to last the project and be tossed at the end (I do have other, perhaps better ones but wanted two identical units to optimize battery usage). Both still work, though two of the battery packs are long dead. Good deal? Well, OK, but not great. But a Millwalkee (spelled wrong!) that I got at the same time, for twice as much lasted how long: half way though the construction. Burned out the motor. Replaced the motor. Burned it out again four days latter. Oops, not a good value!
