offset from the center of the table. Reposition the
drill head as follows:
1. Loosen the two clamping hex nuts using the
hex socket wrench provided with the machine.
2. The swing the drill head to the desired
posit ion.
The table can be raised or lowered to
accommodate the height of the workpiece. To raise
or lower the table, loosen the table lock using the
hand cr a nk. T he n use t he ha nd c ra nk to m ove the
table to the desired height. Then lock the table in
position.
Figure 8
Radial Head Adjustment (All Models)
Change the radial position of
the drill head only if the drill press base is
secured to the floor. Swinging the drill head
without the base being secured to the floor will
cause the drill press to become unstable and
tip over resulting in injury and/or damage to the
machine.
2. A djust the speed pickup gap to approximately
1/8-inch. Re-tighten screws.
3. Operate drill press to verify that speed readout
is operating correctly.
Operating Precautions
The following operating and safety precautions
must be observed in order to avoid harm to the
operator or damage to the drill press.
1. The head assembly must be locked to the
column so the thrust produced by drilling will
not force the head assembly up the column .
2. The work table must be locked to the column
so it will not be forced down the column.
3. Before drilling, release the quill lock nut to
permit free travel of the quill.
4. Be sure the belt is tightened to the proper
tension.
5. DO NOT start to drill the workpiece until
making certain the workpiece is held down
securely.
6. MAKE SURE THE DRIVE MOTOR IS RUNNING BEFORE turning the speed control
handwheel in either direction.
7. Point of operation protection is required for
maximum safety. This remains the
responsibility of the user/purchaser since
conditions differ between jobs.
8. Make sure the drill is secured in the spindle or
chuck before attempting to use the drill press.
9. Mak e sure the spindle taper is clean and f ree
of burrs, scoring, and galling to assure
maximum gripping.
10. Lock the quill in position when using any sideloaded tool.

Drilling Recommendations
Indication of Extreme Speeds and
Feeds
Speeds for Drilling
The speed of a drill is u s ually me a s ure d i n t e rms of
the rate at which the outer periphery of the tool
moves in relation to the work being drilled. The
common term for this is Surface Feet per Minute
(SFM). The relationship of S FM is expressed in the
fol lowing formulas :
SFM = 0.26 X rpm X Drill Diameter (i n inc hes)
RPM = 3.8 x ________SFM__________
Drill diameter (in inches)
In general, the higher the speed the shorter the drill
life. Operating at the low end of the speed range
for a particular material will result in longer life. The
most efficient speed for operating a drill depends
on many variables:
1. Composition and har dnes s of m aterial.
2. Depth of the hole.
3. Efficiency of t he cutting fluid.
4. Type and conditi on of the drilling machine.
5. Desired quali ty of the hole.
6. Difficulty of set-up.
Feeds for Drilling
The feed of a drill is gover ned by the size of the
tool and the material drilled. Because the feed rate
partially determines the rate of production and also
is a factor in tool life, it should be chosen carefully
for each job. In general, the most effect ive feeds
will be found in the following ranges:
Diameter of Drill Feed per Revolution
(inches) (inches)
Under 1/8 .................... 0.001 to 0.002
1/8 to 1/4 ..................... 0.002 to 0.004
1/4 to 1/2 ..................... 0.004 to 0.007
1/2 to 5/8 ..................... 0.007 to 0.015
A drill that splits up the web is evidence of too
much feed or insufficient tip clearance at the center
as a result of improper grinding. The rapid wearing
away of the extreme outer corners of the cutting
edges indicates that the speed is too high. A drill
chipping or braking out at the cutting edges
indicates that either the feed is too heavy or the
drill has been ground with too much tip clearance.
In cases where carbon steel drills are applicable,
the drill should be run at speeds of from 40 to 50
percent of those given ab ove.
14
Optional Equipment
Coolant System Installation
1. Remove the large reservoir cover plate from
the machine base. Tap 1/4-20 threads in the 4
pilot holes.
2. Install the cover plate back onto the machine
