wood is fine try using a very tight grain wood or even "nova ply"
i understand you can not always back your work up like drilling pipe or
on site eye beams , etc
but here is a grind that will minimise drill pulling when drill goes thru
and it lends itself for longer lasting , takes a slight more physical energy
but worth the expense for the results , recommended grind for brass also

grind the positive rake on the drill to nuetral rather than positive
rather than grind till you understand function , use a sharpening stone at first
a few swipes on the face is all you need
be careful not to wrap around to the margin of the drill
i will try to generate better pics on my cad system

drilling principles is one of the most important aspects of machining and
sometimes blacksmithing however somethings are overlooked
