The next thing I need is a "Drill Doctor" to sharpen the good bits as
they get used up.
I have a Drill Doctor in storage. I used to buy bundles of what looked to
be HSS bits at garage sales then pass them through the DD. It does a great
job in sharpening and restoring bits. It has been a while since I have
seen any drill bits at garage sales.
At one time there were several large aerospace companies in San Diego. As
machinists retired then died their stuff would show up in some great garage
sales. Most of the companies have shut down to scatter into other
Congressional districts and Asia so you no longer see those really great
garage sales.
