Follow these Important
Safety Instructions:
Always wear safety glasses to protect eyes from fl ying
debris and chips.
Never continue to use a drill or accessory which appears to
be wobbling, out of round, vibrating or not running true.
Always use drills and accessories rated for 38,000 RPM or
higher.
Never wear loose clothing, dangling jewelry or other apparel
which may become caught in the equipment.
Always keep hands, fi ngers and hair well away from the drill
or other accessories.
Always bolt down the Drill Press for extra stability.
Set-Up and Operation
As you unpack the Drill Press, make sure that you have the
complete assembly (see photo). Loosen the Adjusting Knob
and move the Head Assembly up the Post to the desired
height. Tighten the Knob securely. Be sure that the head,
table and base are aligned and centered.
Foredom recommends bolting the drill press to the work-
bench or platform for extra stability. Insert suitable length
bolts through the four holes provided in the Base Plate.
Fasten to the workbench or to a piece of plywood approxi-
mately 2‘ x 2‘ x 3⁄4 ″.
Arm Adjustment
Test the downstroke action of the handle. This has been
preadjusted at the factory, but may have rattled loose during
shipping. It should feel smooth and free. If it feels too loose,
adjust the Shoulder Screws in the handle arm assembly.
These screws should be tightened snugly.
Inserting the Handpiece
The Locking Ring on the handpiece turns to Release or Secure
accessories in the collet. The ‘wings’ on the Locking Ring
2 knurled ‘wings’ on opposite
sides of the Locking Ring
H.MH-170
Locking Ring
should align vertically with the gap at the front and back of
the Handpiece Holder when inserting the H.MH-170
Micromotor handpiece. Loosen the mounting knob on the
holder and gently slide the handpiece into the handpiece
holder all the way until it is snug. The handpiece should fi t
so far down that the Locking Ring is below the Handpiece
Holder and can twist to open and close positions for changing
out accessories. Re-tighten the knob until the handpiece is
fi rmly held in place. Take care not to tighten and damage the
handpiece. You can now open the collet and insert the bur or
drill bit and close the collet to begin work.
Table Adjustment
Determine the desired table height for the thickness of the
material to be worked. When using a drill, make sure that
the drill tip is aligned with the center of the Table Drill Hole
by moving the drill gently through the hole while the motor
is still off.
Removing Adjustable Table
If you need to remove the adjustable table, the Head Assem-
bly must be removed fi rst. Loosen the Head Adjusting Knob
and slide the Head Assembly up and off the Post.
Note: Make sure that you have a fi rm grip on the Head
Assembly before loosening the knob. It could be damaged
if allowed to drop. Place the head on the work surface,
handle side up. Repeat procedure with the Adjustable Table.
Replace the Handpiece Head Assembly onto the post and
tighten the Adjusting Knob, aligning head and base plate.
Drill Stroke Adjustment
Adjust the drill stroke depth from 0–1-1⁄4 ″ with Lock Nuts.
Move the Depth Stroke Indicator to the desired measure-
ment on the Scale by pressing down on the handle. Hold at
desired setting and move Lock Nuts until the depth indicator
is stopped.
Securing the Workpiece
Slots are provided in the Adjustable Table and Base Plate for
use with clamps, jigs, and other holding devices. Make sure
the workpiece is securely fastened before beginning work.

Drilling
For drilling, generally high-speed steel, cobalt and diamond
drills are most often used. Whatever accessory you use,
let the speed of the tool do the work. Too much feeding
pressure can damage or break your drill, and may cause
loss of control. Twist drills are often used for drilling holes
in metals, woods, and plastics. On work items with rounded
surfaces such as rods, it is a good idea to centerpunch a
starting hole to keep the tip of the drill from “walking” or
wandering from the desired starting point.
When drilling, lift the drill up and down frequently to clear
away dust and chips.
Speed
Always use drills and accessories rated for 38,000 RPM or
higher. Generally, work speed is determined by experience
and varies with the type of material being drilled, the type of
drill or accessory, the thickness of the material, and the type
of work being done. Follow recommendations of the drill or
accessory manufacturer. Usually, higher speeds are used
on soft materials and lower speeds on harder materials. It is
always a good idea to experiment on a scrap piece of mate-
rial before beginning the fi nal work operation.
Coolants
Coolants are sometimes needed to help keep the accessory
cool and to keep the workpiece clean of debris. Which type
to use is determined by the material and the accessory and
will vary with operator preference. Wetting agents with rust
inhibitors, waxes, oils and water are often used when drill-
ing very hard materials such as metals, gems and stones.
Coolent must not be allowed to enter the handpiece.
Lubrication
All unpainted surfaces are sprayed with a rust inhibitor
when shipped. Be sure to clean away all debris after use.
Respray with rust inhibitor when necessary, especially dur-
ing storage. The Spring and two Shoulder Screws should be
lubricated periodically with a light coat of oil.
