The Model W1669/W1670 is designed for drilling holes
in wood, plastic, and 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
down feed levers 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:
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.
SECURING.WORKPIECE.TO.TABLE:
Secure the workpiece
to the table or in a vise that is secured to the table
before drilling.
PROTECTING.TABLE:
Protect the table by placing the
workpiece on scrap wood, or center the location of the
hole to be drilled over the pocket in the table when
through drilling. Also, make use of 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,.Cutter,.and.
Hole.Saw.Suggested.RPM.Chart
on
Page.27
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:
Harder materials (steel vs. wood)
require slower drilling speeds.
SOFT.MATERIAL:
Soft materials require a faster drilling
speed. (
NOTE:
Plastics can melt at too high of a spindle
speed!)
Drilling
LUBRICANT:
Use lubricant on all materials
except wood and cast iron. Refer to
Lubrication.Suggestions
on
Page.26.
to find the correct lubrication for your
application.
DRILLING.ACCURACY:
To prevent drill bit
wandering 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.
5-FLUTE/2-FLUTE.CUTTERS:
Use a 5-flute
cutter 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
plastic 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 drilling from the other
side.
