Drilling Wood
Twist bits, which are intended for metal, may also
be used for boring holes in wood. Machine spur
bits are generally preferred, they cut a square
bottomed hole and are designed for removal of
wood chips. Do not use hand bits which have a
screw tip; at drill press speeds they turn into the
wood too fast and tend to lift the workpiece off the
table and spin it.
For through boring, line up the hole in the work
table with the bit to avoid damaging its tip. Scribe
a vertical line on the column and a matching line
on the table bracket so the table can be clamped
in the center position at any height. Use a piece
of scrap wood under your workpiece and feed the
bit into the wood slowly to prevent splintering the
bottom side of the workpiece.
When using your drill press for operations such
as shaping, sanding or mortising, use jigs, fix-
tures or hold-downs that are appropriate. For
more information, review reference materials per-
taining to your specific application.
The chuck will accept any tool with up to a
5
⁄8"
shank. Do not attempt to open the chuck wider by
forcing it.
