OPERATION
7. If the bit jams in the workpiece or if
the drill stalls, stop the tool immediately.
Remove the bit from the workpiece and
determine the reason for jamming.
DRILLING IN WOOD
For maximum performance, use high-speed
steel (available separately) or brad-point
bits (available separately) for wood drilling.
1. When drilling “through” holes, place
a block of wood behind the workpiece to
prevent ragged or splintered edges on the
back side of the hole.
2. Begin drilling at a very low speed to
prevent the bit from slipping off the starting
point.
3. Increase speed as the drill bit bites into
the material.
DRILLING IN METAL
For maximum performance, use high-speed
steel bits (available separately) for metal or
steel drilling.
1. When drilling metals, use light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the bit and increase
the drilling efciency.
2. Begin drilling at a very low speed to
prevent the bit from slipping off the starting
point.
3. Maintain a speed and a pressure that
allow cutting without overheating the bit.
Applying too much pressure will:
• Overheat the drill/driver
• Wear the bearings
• Bend or burn bits
• Produce off-center or irregularly shaped
holes
SCREWDRIVER OPERATION
1. Select the desired speed/torque range
to match the planned operation.
2. Attach the desired driving bit into the
chuck.
3. Make a few practice runs in a scrap
piece before working.
