Forward/Reverse Switch
The reversing switch is located on the bottom
right of the D-handle. ALWAYS allow the
chuck to come to a complete stop before
changing rotation.
1. Push the switch to the back for FOR-
WARD (clockwise) rotation.
2. Push the switch forward for REVERSE
(counterclockwise) rotation.
Extended Side Handle for D-Handle Drills
An extended side handle is supplied with all
D-Handle drills. It can be attached to the
gear case on either side of the drill. Because
of the high torque of this drill, the side handle
must always be used when operating the
drill. To attach the side handle, screw the
threaded end of the side handle into the hole
on the drill's gear case.
Ring Clamp Side Handle For Right
Angle Drive Unit
A ring clamp side handle is supplied with
Right Angle Drive Units. This handle clamps
onto the Right Angle Drive Unit and swivels
360° to be locked tight in any position. When
using the D-Handle Drill without the Right
Angle Drive Unit, do not clamp the ring clamp
side handle to the front of the gear case;
instead, use the extended side handle.
WARNING !
To reduce the risk of injury, always use a
side handle when using D-Handle Drills
and Right Angle Drive Units. This tool
operates with high torque. Always brace
or hold the tool securely.
Starting
Place the drill bit on the work surface and
apply firm pressure before starting. A center
punch may be used to make starting easier.
On units with trigger speed control, start
drilling slowly to allow maximum control and
to prevent the bit from wandering. When the
hole has been properly started, increase the
speed.
Stalling
If the tool stalls, reverse the motor, remove
the bit from the work and start again. With
speed control units, if the drill is slowing down
1107-50 / 3107-4
due to loading, increase the speed until the
tool operates properly.
Speed
Increasing the speed of the drill permits in-
creasing the amount of pressure applied;
however, too much pressure will slow the drill
bit and retard drilling efficiency. Too little
pressure will cause the bit to slide over the
work and cause excessive friction which will
dull the point of the bit.

and Moving Parts

Before drilling, clamp the workpiece down
securely and brace the tool firmly. This helps
assure an accurately cut hole and helps
prevent personal injury should the bit bind.
When drilling wood, composition materials
and plastic, start the drill slowly. Increase
speed as drilling progresses. Low speeds
are recommended for plastics with low melt-
ing point.
When drilling holes in heavier gage metals,
maintain an efficient drilling speed.
NOTE: Keep the speed low enough to pre-
vent burning the bit.
When drilling holes in light metal or thin
pieces or wood, back the material to prevent
binding, distortion or splintering on break-
through.

When drilling masonry with carbide-tipped
bits, high speeds are most effective. Drilling
soft masonry materials such as cinder block
requires little pressure. Hard materials, like
concrete, require more pressure. In either
case, do not let the carbide-tipped bits spin in
the hole without cutting, as this will damage
