Tapping operations using the reverse feature
1. Drill the initial hole on the drill press for accuracy of diameter. If the diameter
is 1/2 inch or larger, drill a pilot hole about half that diameter first.
2. Make sure the hole has a large enough chamfer. If the chamfer is too small
the tap will work a little hard when starting the tapping operation.
3. Select the tap type. Choose from a taper tap (recommended), plug tap or
bottoming tap. The taper tap has several chamfer threads forming a tapered
cone on the inserting end. The plug tap has fewer chamfer threads and a
bottoming tap only has a couple chamfer threads.
4. Match the tap size. Use the specified tap size to thread the hole diameter.
Taps that are sold with drill bits are size matched for you. The taps
themselves may show the hole size they’re intended for, but it’s likely to be
given in metric notation. Use a conversion chart to match this with the inch
fractions measuring drill bits.
5. Cut the threads. Lubricate the tap with tapping fluid. Start the drill press and
lower the tap gently into the hole to be threaded. It only takes a few seconds
to tap a hole. When the tap gets to the desired depth reverse the direction of
the spindle and the tap will work its way out. As long as it has been set up
properly, the chances are good for success.
Tips for tapping
Tapping is a skill. It takes practice to do it well and to not break taps. If you’re
new to tapping, practice on sample stock before tapping into your actual
project
Materials have differing requirements for drill speed and lubrication. Hole
depths and diameters may present additional drilling requirements. Refer to
material charts for drilling specifications.

1. BASIC OPERATION (PROCEDURE)
Drill / Chuck Installation:
To show greater detail
Chuck guard is in the open position in POWER MUST BE OFF BEFORE
photos. CHUCK GUARD MUST IN MAKING ANY ADJUSTMENTS!
PLACE DURING OPERATION! TURN POWER OFF! Before inserting
drill bits, chucks or arbors, always clean
out spindle hole and taper hole with a
clean cloth.
Open chuck jaws completely by turning
attached chuck key counter-clockwise
until the jaws are fully opened.
To install the chuck to the arbor tightly,
slide the chuck into the taper forcing it
into the spindle with by hand. Place a
block of wood on the table then lower the
spindle to make contact with the wood
and press the chuck tightly into the
spindles taper.
Install a taper shaft drill bit into the taper
the same way as you would the chuck. If
an adaptor is used it must fit the taper
correctly and the bit must fit snug in the
adaptor.
Installation of drill bits in the chuck:
A drill bit with a shaft of at least 1” long
should be used to allow correct chuck jaw
contact. If shaft length is less than 1” do
not insert bit as far into the chuck where it
allows jaw contact with drill flutes. Center
drill bit onto the chuck and tighten the
chuck securely with the chuck key.

8
Note:
•Always use sharp, straight bits.
•Never use bits with turned down
shafts.
•Never exceed the maximum diameter
bit size for the machine.
•Always wear appropriate clothing
while operating the drill press.
•All guards and interlocks must be in
place when operating the machine.
Correct: Jaws Incorrect: Jaws
contact drill shaft contact drill flutes
Wedge removal tool Tooling removal:
Before removing the chuck or bit from the
machine; be sure the spindle has come to
a complete stop and power is off. If needed,
rotate spindle by hand to align the spindle
and quill openings. Insert the wedge
removal tool, while supporting the tooling,
and tap the wedge to remove the tooling.
Work holding:
When drilling directly on table surface, it is recommended that a
piece of wood or plywood be clamped securely to table under the
work piece. This will minimize splintering or burring as the drill breaks
through. It will help minimize drill bit and table damage.
Clamp the work piece to the table whenever possible. The table has
“T” slots that allow for many different clamping configurations.
When part cannot be affixed to the table a drill vise that is bolted in
place is recommended.

9
Table lock Table height adjustment:
Table height adjustment is
accomplished by loosening the clamp
Bolt, then adjusting the table with the
bracket handle to desired height. After
table is at working height, retighten
the clamp bolt securely.
Note: Keep table adjustment rack
clean from debris. Never attempt to
move table with clamp bolt tightened.
Table handle
Table tilting adjustment:
Using an adjustable or box wrench,
loosen table level lock bolt. Carefully tilt
the table to the degree needed, as shown
on the angle index scale located on the
table rotation point. Retighten nut
securely.
Note: Never tilt table if any material or
fixturing is on it. Only make adjustments
when table is free of loose articles.
Table swing adjustment:
To swing the table up to 360 degrees,
loosen the clamp release bolt and swing
table to the desired position. After the
table is in the correct position tighten
clamp release bolt securely.
Note: Never swing table if any material or
fixturing is on it. Only make adjustments
when table is free of loose articles.

SPINDLE DEPTH AND FEED OPERATION
Depth setting
Loosen the depth locking handle by turning it counter clockwise. When this is loose
you can turn the depth gauge to the desired depth.
Zigzag line is for auto feed depth operations
Straight line is for manual depth feed operations
After setting depth tighten the depth locking handle.
Manual feed operation
With the spindle in operation and the feed handle in the manual feed position pull
the feed handle down making contact with the work material.
Auto feed operation
With the spindle in operation, pull the feed handle out away from the drill press as
shown above (auto feed handle position). The spindle will begin to feed down. The
faster the spindle rotates the faster the spindle will feed down. The slower the
spindle rotates the slower the feed rate. If you want to stop the feed down
movement move the feed handle to the manual position and the spindle will go back
up to the starting position.

2. MAINTENANCE OF MACHINE
MAINTENANCE
BELT TENSION ADJUSTMENT
Proper belt tension is approx. 10 lbs. of pressure or deflection of about 1/2 “
1. On a regular basis blow out any dust that may accumulate inside
the motor. (Frequency depends on environment the machine is
in)
2. A coat of automotive wax applied to the table and column will help
to keep the surface clean.
3. All of the ball bearings are packed with grease at the factory. They
require no further lubrication.
4. Periodically lubricate the gear and rack table elevation
mechanism, the spindle splines and the rack (teeth on the quill).
5. After each use the machine should be cleaned. Weekly
lubrication of all sliding or moving parts with light weight or way oil
is recommended. For your own safely, turn switch “OFF” and
remove plug from power source outlet before maintaining or
lubricating your drill press.
