G9969 Radial Drill Press
The Model G9969 is designed for drilling holes
in wood, plastics or metal. The basic operation
of a drill press is lining up your drill bit with the
intended hole location, turning the drill press
ON ,
and using the downfeed handles to move the
spinning drill bit into the workpiece at a steady
and controlled feed rate.
For safe operation and optimum results, it
is very important to follow these guidelines
when drilling
:
SECURING WORKPIECE TO BASE:
Secure the
workpiece to the base or in a vise that is secured
to the base before drilling.
CLEARING CHIPS:
Raise the drill bit often to
clear chips and cool the drill bit. This will ease the
work of the drill press motor and extend the life of
your drill bits.
PROTECTING BASE: Protect the base 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 23 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.
Basic Drilling
Operations
Larger bits turning at slower speeds tend
to grab the workpiece aggressively. When
using large bits, always clamp the work-
piece to the base to prevent injuries. Failure
to heed this caution can result in the oper-
ator's hand being pulled into the bit or the
workpiece being thrown with great force,
causing serious personal injury!
HARD MATERIAL:
The harder the material,
(steel vs. wood) the slower the spindle speed.
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 and cast iron. Refer to
Lubrication Suggestions on Page 23 to find the
correct lubrication 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.
