Margin Drill Bits & Negative Relief: Using the stan-
dard drill setting align the bit in the chuck. Visually
check the alignment of the bit before sharpening. Note
the position of the two chuck flats, (remember the flats

hold true on drill bits from 3/32" to 1/2". If the line
does not fall on the heel, then the alignment tube must
be adjusted. If the line falls to the right of the heel,
move tube slightly below the standard setting. The
chisel edge will rotate clockwise if the alignment set-
