Please read these safety instructions
thoroughly before operating this tool.
They are for your protection and
should always be followed to reduce
the risk of personal injury or damage
to the handpiece.
Never run Handpiece in
Reverse direction.
Form 1214 n 12/09 Printed in U.S.A.
See your Power Tool Owner's Manual
for complete instructions on use, care
and maintenance.
Always wear proper eye protection
while using this handpiece.
Never use a damaged, bent, vibrating,
or out of balance chisel, cutter, gouge,
or other tool bit.
Cutting Tips
Practice on some scrap wood to become
familiar with the feel and characteristics of the
H.50
and H.50C Handpiece and cutters.
For the best results the angle of the handpiece
to the work should be about 45° when using
a V type cutter. Carve at a 30° angle when
using round edged cutters and gouges.
Press the cutting tip into the wood gently and
increase the flexible shaft speed slowly to
make fine shallow cuts. To make deeper cuts
add a little more pressure.
Always cut away from your other
hand or body.
Optimum Cutting Speed is 1,000 —
8,000 RPM. Running at higher speeds
will lead to heat, vibration, and
excess cam wear.
Safety Instructions
Always cut away from your other
hand or body.
Optimum Cutting Speed is
1,000 – 8,000 RPM.
The H.50 and H.50C Chisel Handpiece
can only be used in the forward motor
rotation direction. Using the H.50 Handpiece
in reverse will cause severe damage to the
handpiece and flexible shaft.
Always wear proper eye and face
protection. Wear safety glasses or a face
shield whenever you operate a Foredom Flexible
Shaft machine or any power tool to prevent
serious eye injury.
The H.50 and H.50C Handpiece should
only be used with Foredom Cutters.
Never use other chisels and gouges in this
handpiece as they may not fit properly or be too
large for safe use.
Do not run or use the handpiece
while the locking nut is loose.
Cutters, chisels and gouges should be
kept sharp. Dull or blunt tools require more
effort while sharp tools cut easily and with
more control.
Never change cutters, chisels, gouges, or tool
bits while motor switch is in the ON or FOR
(forward) or REV (reverse) position.
Never sharpen cutter, chisel or gouge when it
is mounted in the H.50 and H.50C Handpiece.
Always remove chisel or tool bit for sharpening.
Never use or continue to use any chisel,
cutter, gouge or other tool bit that is damaged,
bent, loose, vibrating or out of balance. Inspect
each accessory for cracks or flaws before using.
Avoid knots, imperfections in the wood or
metal objects like nails, which could catch or
damage the tool bit. Let the speed of the tool
do the work.
Do not apply heavy pressure to the tool bit.
Always insert the cutter, chisel or gouge fully into
the plunger shaft slot. Never use an adapter, extension
or other device to mount other chisels, cutters
or gouges.
Secure the work piece that you are carving in
a vise or other work holding device. Holding it
with your hand is dangerous and can result in serious
hand injury.
Never wear open shoes or sandals. Use footwear that
is tough enough to protect your feet from falling tools.
Keep both hands and fingers away from the
cutting edge at all times.
Never cut or exert pressure, toward your hand or any
other part of your body.
Do not wear loose fitting clothing or jewelry.
Loose clothing or jewelry can be come entangled in
the tool. Do not wear items such as neckties, neck-
laces, or bracelets when operating power tools.
Secure or tie back long hair.
Use both hands whenever possible to hold and
guide the carving tool.
Always use a proper dust collection system or wear a
respirator to prevent the inhalation of dust particles, or
other debris into the lungs.
Assembly Instructions
Attaching the Handpiece
To attach the handpiece, be sure that the keyed tip of
the flexible shaft is properly lined up with the slot in
the back end of the handpiece by looking into the rear
of the handpiece before pushing it on. If it is not in
line, turn the shaft tip or the handpiece to the correct
position (see illustration). To remove the handpiece,
simply pull the handpiece off the shaft and sheath
with a firm grip while the motor is not running.

Maintenance and Lubrication
The H.50 and H.50C Handpiece requires little maintenance to keep
it running at peak performance. Keep it dry, free of debris and
lubricated for a long trouble-free life.
After every 200 hours of use you should clean and lubricate the
H.50 and H.50C Handpiece. The old grease must be cleaned off of
the interior cam chamber and replaced with new lubricant.
1. First remove the chisel, gouge or cutter tip from the handpiece.
2. Next remove the handpiece from the flexible shaft. Follow
“Attaching Handpiece Instructions” on reverse.
3. Unscrew (counterclockwise) the aluminum housing ring (#15)
and Q.D. connector (#12). To prevent the pliers from marring the
aluminum, wrap it in a rag or piece of leather.
4. Now you can carefully separate the halves of the black plastic
top housing (#6) and bottom housing (#14). Keep the spindle/
plunger assembly in one half of the black plastic housing. Be
careful not to lose or displace the small pin guide inserts (#5).
5. Gently wipe out the grease from the empty half of the housing
with a small clean rag or Q-tip.
6. Carefully remove the spindle/ plunger assemblies making sure
not to disassemble either and gently wipe off the old grease with a
soft clean rag.
7. Clean the other half of the housing with a small clean rag or
Q-tip and replace the cleaned spindle/plunger assemblies in one
half of the housing.
8. Squeeze a thin line (1/8 ″ thick, no more!) of Foredom ® Chisel
Handpiece Grease (p/n MS10008) from the plunger pin (#3) to the
furthest of the two actuating cam gears (#13). Do Not put grease
beyond this cam as the ball bearings do not require grease.
9. Replace the remaining half of the housing taking care that the
plunger pin is inserted in the pin guide insert (#5) and that the
sleeve bearings and ball bearing fit into their respective slots.
10. Carefully screw the metal Q.D. connector and metal housing
ring onto the softer plastic top and bottom housing, making sure
that you do not cross-thread them. Attach the handpiece to the
flexible shaft and run slowly for 5 minutes to redistribute the grease
before resuming carving.

IMPORTANT INSTRUCTIONS
put a thin line
of lubricant here
To operate within the 1,000 – 8,000 RPM optimum cutting
speed, we recommend the use of a bench top dial control (C.EM
or C.EMX) in place of the more common foot pedal. Running at
higher speeds will lead to heat, vibration, and excess cam wear.
Attaching and Mounting
Cutters, Chisels, or Gouges
1. Remove the H.50 Handpiece from
the flexible shaft or make sure that the
flexible shaft motor switch is OFF.
2. Loosen the locking nut with the supplied
12mm spanner wrench by unscrewing it
counterclockwise.
3. Choose a chisel, gouge, or cutter and with
the protective cap still in place insert the tang
fully into the plunger shaft. Tighten the locking
nut clockwise until chisel or tool bit is held
securely. Do not over tighten. Once the
accessory tip is mounted and the protective cap is removed, you can re-
attach the handpiece, turn on the flexible shaft machine and begin to carve.
