[AT] Drill bits

[Carl Gogol]

I have a Drill Doctor about 5 years old and like it except I can never 
remember to change the angle setting to the drill I have in hand.  So it 
gets a new cutting angle or I have to do it again and it takes a lot more 
time since you do remove a lot more material in this two step process.  If I 
follow the directions the drills cut like new.
Through the years I have found a good sale for some of the important sizes 
of drills in Cobalt and buy a batch of 10 or 20 - you just can't beat the 
performance of Cobalt on steel.  The DD will sharpen these but you must 
remember to use the right angle - for sure.

I use a drill doctor and like it.  I have mixed success free-handing.   When 
I free-hand they are sharper than before, but not like new.   With the drill 
doctor they are like new.    I will be the first to admit that I am a bad 
hand sharpener and others(maybe you also) might get great results free 
handing.

Size is a problem with the drill doctor.  Each model sharpens certain sizes. 
So the occasional large bit still has to be sharpened by hand unless you get 
the top-of-line model or an optional chuck.    In addition, wood boring 
spade bits cannot be done by any model except one.  And that model cannot do 
large twist bits I fi remember right.  I am sure they have a web site that 
can help you choose though.

Hope this helps,

Spencer
