Something like that you can probably do while holding the bit
in a drill against a grinding wheel and go slowly, dip the end
in water frequently.


If you can get a piece of hardened rod down .070+-.005 on the full length
of
0.650" on such a setup AND keep it round you are a master machinist! And
NOT water, but cutting oil or coolant, NEVER water! You are NOT a master
machinist!


If you're using a grinder, water is just fine. The idea is to
keep it cool.


You are no machinist. The water does more than keep it cool. It needs a
lubricant and the water does not do a very good job of lubrication. Oil or
coolant keeps the part from becoming brittle.

Aha - look half way down http://www.wihatools.com/700_BitHolders.htm


There I am with the same thing as the DeWalt, PLUS shipping and handling!
From the picture I can tell that the diameter is too large!


Uh, no, take a look at the shank lengths. It's 1/4" hex stock, _not_
the outer diameter. #71433 would have probably done you, #71435
definately would.

I am not talking about the hex part, but the cylindrical part that the bit
sits in. The diameter is too large. The OUTER diameter is why I can't use
the DeWalt bit holder. The OUTER diameter needs to be turned down ABOVE the
hex.
