[AT] Drill bits

[jtchall at nc.rr.com]

Made in USA cutting tools are American made generic cutting tools, usually 
no fancy stuff or coatings. Most machine shop suppliers carry them. You only 
see them in basic tools. Some of them are even made by the same companies 
making name brand. When you buy name brand, Lord only knows where it will be 
coming from, but at least it will be good quality. When I am buying cutting 
tools for use at the farm shop, I stick with "made in USA" or the cheapest 
name brand due to budget  reasons. At work I almost always buy name brand, 
unless we only need the tool very briefly and may opt to save a few bucks.

John, you must be physic  :) I was just going to ask what bits to buy.
Whether or not I go with a sharpener or not, I must replace most of my bits.

Great advice below, I will start shopping.

Thanks
