Tuning pin drilling? followup

    The bit I use is cheap as you can get.  It only has  to be round and have 
a pointed tip so it puts just the slightest dimple in  the Block.  As Ron 
said The bits I drill with I've had for along time as  well.  I think they came 
from Pianotech.
 Small forstner bits will work as well.  If they don't fit in the  hole grind 
the outer diameter just enough until they do and the block will have  a 
dimple right in the middle.  You can't miss.
  BTW  I always ream out the holes in the plate webbing to make  each hole 
the same size.  I don't usually end up taking much out but I am  surprised how 
inconsistent the size of these holes are. On some holes nothing  comes out 
others don't seem to be bored with the same bit. Which,  they  probably weren't.

Yes,  that's nice and simple... the brad point bits I've tried to use have 
trouble  clearing the
chips..get all jambed up...

What does the cutting  portion of the tip look like,  and who is your 
supplier...if I  may?
