[AT] drill bits

I bought a very good set of drill bits in a screw top holder at the 
farms show.   It was the American Made Bit Sales booth.   They have a 
lifetime sharpening and replacement guarantee.   However, I had mine 
sharpened lately, and the sharpened ones seem to be a lot shorter and 
they dull much quicker.  My advice would be to just break the bit if you 
want it sharpened by them and give them the broken piece that goes in 
the drill.   I got the mechanics length set that has 3 flats on the bits 
for a 3/8 drill.  The set goes from 1/16 to 1/2 by 1/64  i think the set 
is made by Triumph.

I have been buying cheap throw away Harbor Freight titanium nitride coated bits but have gone back to using high speed steel bits.  Even the higher quality coated bits don't seem to work as good as the high speed steel bits.
