OPERATION
Correct Drilling Speeds
See ''Changing Speeds" section under "Controls and
Adjustments" and Speed Chart inside Pulley Cover for cor­
rect drilling speeds. Always disconnect tool from power
source before making any adjustments. Care must be taken
when setting speed for any cutting tool or accessory not list­
ed on chart. Read and follow any speed Instructions supplied
with cutting too! or accessory Rules for judging drilling
speed for materials not listed in chart are:
1, A small size drill requires faster cutting speeds than a
larger size,
2, Soft material requires faster speeds than hard material.
See "Accessories" section for a listing of items authorized for
use with this tool,
bottomed hole Be careful NOT to use any SCREW TIP
hand drill bit. At even the slowest drill press speeds, this style
will lift the workpiece from the table and could easily cause
injury.
Feed bit slowly through wood. As bit is about to cut through
bottom surface, slow feed even more to prevent splintering
or a burr to bottom face of workpiece. Always use a piece of
scrap wood under workpiece to reduce splintering and to pro­
tect drill bit and work table.
Use of clamps or a work vise is recommended for most
drilling operations, If a method of damping is not used, brace
back-up material against left side of column to prevent work­
piece from spinning.
Drilling Metal
Drilling Wood
Many types of drill bits designed for drilling or boring wood
can be used with this machine. Standard high speed twist
drills intended primarily for metal drilling work very well on
wood. Spur bits, sometimes referred to as forstner bits, are
best for woodworking because they cut a clean-sided, flat
Although primarily a woodworking tool, this Radial Drill Press
can be used to drill metal. Always firmly clamp or use a
drill press vise bolted to work table when drilling metal.
A WARNING: N ever hold a metal workpiece in a
BARE HAND DURING DRILLING. FIRHALY CLAMP WORK­
PIECE TO TABLE OB USE A DRILL PRESS VISE BOLTED TO
TABLE WHENEVER DRILLING METAL. FAILURE TO DO THIS
COULD RESULT IN PERSONAL INJURY.
MAINTENANCE
A
WARNING: F or you own safety , turn OFF
POWER AND DISCONNECT TOOL FROM POWER SOURCE
BEFORE PERFORMING ANY MAINTENANCE.
Periodically clean dust accumulation from machine. Apply a
light coat of paste wax to table, base work surfaces, and ver­
tical and horizontal columns. This will help to keep them
dean and working smoothly.
All of the ball bearings are packed with grease at the factory
and require no further lubrication. The Quill and Spindle Rack
should be lubricated periodically with a light machine or pen­
etrating oil Open Pulley Cover and spray a light coat of oil
on Spindle Shaft splines (REF 42) as you move spindle up
and down. Avoid getting any oil on the drive bell. Also, with
spindle in fully down position, spray a light coat of oil on Quill
(REF 40). A small amount of grease on Table Lift Gear (REF
7) and Horizontal Feed Gear (REF 90) will keep these two
mechanisms moving freely. Wipe excess grease from racks
to prevent dust buildup in teeth.
