You can buy inferior tools at HF and swapmeets and evilbay. Or buy quality name-brand tools that will maintain accuracy and last several lifetimes. I have the same set of USA-made drills (number/letter/fractional) I bought 20 years ago. You can still cut your finger on the flutes if not careful!!!!!! I have not needed to re-sharpen them on my Darex yet. But I have a cheeeeepo set of HF drills I use for general construction and drilling of the same sizes that I have resharpened at least 6 times in the past 8 years.
Same goes for lay-out tools. Starrett only here.
Same with taps and dies, hammers, screwdrivers, and any other tool. Quality trumps cheap ever time.
Buy what you can afford. But think ahead and buy tools that you grandchildren can use!!! I have many precision tools from the late 1800's that are still as useful and accurate as the day they were made.
