PRE-SETTING THE DRILLING DEPTH
BENCH TYPE
To set the depth of the hole, adjust the depth stop as follows:
1.
Lower the chuck with the power OFF, un l the drill bit touches the surface
of the workpiece, and hold in that posi on.
2.
Spin down the adjuster nut so that the
gap between its underside and top of
bracket is the depth of the hole required.
Screw down the lock nut and lock it
against the adjuster nut.
The drill is now set to drill holes to your pre-determined depth from that
par cular start point. i.e. Providing the surface of your workpiece is
fl
at and level,
you may drill a series of holes, each to the same depth.
The scale and pointer can be used when drilling individual holes.
Lower the chuck un l the drill bit touches the work, set the pointer against a
point on the scale, and proceed to drill to the required depth, using the scale.
