Re: CNC drill sharpening

I have a couple custom shops here in the phila area. they will take
blanks of the material and make what you need. Figure $30 to $50 for
set-up then $5-$10 for the blank (1/4 carbide ?? x 3" long??) then
some $$ for the work. it gets cheaper the more you have done at one
time. The first is usually about $50.00

You can save a dollar or two if you use coblat and another 50 cents
if you use HSS, but why ?? at $47.50 for HSS or $48.00 for Cobalt or
$50.00 for carbide.


Obviously, the larger dia the bit, the more time grinding and the
more $$$ for the blank.
