G1005Z Mill/Drill
The Model G1005Z is designed for drilling holes in
wood, plastics or metal. Basic operation consists
of lining up your drill bit with the intended hole
location, turning the mill/drill
ON, and using the
downfeed handles to move the spinning drill bit
into the workpiece.
For safe operation and optimum results, it
is very important to follow these guidelines
when drilling:
SECURING WORKPIECE TO TABLE: Secure
the workpiece to the table or in a vise that is
secured to the table before drilling.
CLEARING CHIPS: Raise the drill bit often to
clear chips and cool the drill bit. This will ease
the work of the mill/drill motor and extend the life
of your drill bits.
PROTECTING TABLE: Protect the table by plac
-
ing the workpiece on scrap wood. Also, use the
depth stop so that the drill bit goes no deeper
than necessary.
USING CORRECT SPEEDS: Use the correct
speed for the diameter of the drill bit being used
and the type of material being drilled. Refer to the
Drill Bit Speed Chart on Page 22
to help you
choose the correct speed for your application.
LARGE DIAMETER BITS: Large diameter drill
bits require slower spindle speeds.
SMALL DIAMETER BITS: Smaller diameter drill
bits require faster spindle speeds.
HARD MATERIAL: The harder the material,
(steel vs. wood) the slower the spindle speed.
Drilling Guidelines
Larger bits turning at slower speeds tend
to grab the workpiece aggressively. This
can result in the operator's hand being
pulled into the bit or the workpiece being
thrown with great force. Always clamp the
workpiece to the table to prevent injuries.
SOFT MATERIAL: The softer the material, the
faster the spindle may turn. (Plastics can melt at
too high of a spindle speed!)
LUBRICANT: Use some form of lubricant on
all materials except wood. Refer to Lubrication
Suggestions on Page 21
to find the correct lubri-
cation for your application.
DRILLING ACCURACY: To prevent drill bit wan
-
dering and ensure accurate placement of holes,
mark the hole location with a center punch before
drilling. Also consider using a center-point drill to
start the hole.
PLUG/ROSETTE CUTTERS: Plug cutters and
rosette cutters are for wood only. However, car
-
bide-tipped bits and cutters cut at a higher speed
and can cut materials other than wood, depending
on the cutter type.
5-FLUTE/2-FLUTE CUTTERS: Use a 5-flute cut
-
ter when cutting into plastics, brass, aluminum,
and mild steel. A 2-flute cutter can aggressively
grab the workpiece and damage the tool if used
with materials other than wood.
SPADE BITS AND PLASTIC: When drilling plas
-
tic with a spade bit, use a spade bit with spurs.
HOLE SAWS: When using hole saws, apply firm
and even pressure, so the saw teeth contact the
surface all at the same time—not at an angle. You
can also flip the workpiece and finish cutting from
the other side.
