nsTalling drills
Insert the drill into chuck jaws about 25.4 mm long. When using a small drill, do not insert it so far that the jaws
touch the flutes of the drill. Make sure that the drill is centered in the chuck before tightening the chuck with the key
(fig. 17).
6.2 p
osiTioning The work piece
Always place a piece of wood or plywood on the table. This will prevent "splintering" or making heavy burrs on the
underside of the work piece as the drill breaks through. The wood should make contact with the left side of the
column (fig. 18).
6.3 U
sing The vice
For small work pieces that cannot be clamped to the table, use a drill press vice. The vice must be clamped or bolted
to the table.
