SAFETY FIRST
Speed Reducer
Welcome to Hougen
Congratulations on your purchase of the Holcutter™ Speed
Reducer. Your Speed Reducer is designed to reduce RPMs
while maintaining torque when using large diameter Holcut-
ters™. The Speed reducer can be connected directly to a
drill in place of the chuck or held in the drill’s chuck. The 4:1
gear ratio allows a drill turning at 1000RPM to reduce the
cutter output to 250 RPM. This allows for a more correct
cutting RPM for the large diameter Holcutters. Through con-
stant innovation and development, Hougen is committed to
provide you with hole-producing tools and products to help
you be more productive.
Before attempting to operate your new Speed Reducer,
please read all instructions fi rst. These include the Oper-
ator’s Manual and Warning Label on the unit itself. With
proper use, care, and maintenance, your model will provide
you with years of effective holemaking performance. Once
again, thank you for selecting our product and welcome to
Hougen.
The Speed Reducer is capable of producing high torque:
•
Always keep a fi rm grip on both handles when
drilling.
• Do not overreach or overextend while drilling; it
is best to keep the tool close to your body.
• Work from a stable stance.
• Pay attention to your work.
• Always wear safety glasses and gloves.
• Do not use the Speed Reducer without the
Clamp Handle.
• Always use Slick-Stik™ lubricant when cutting.

Optional Parts:
INSTALLATION METHOD #1
04942 Thread Adapter (1/2-20-UNF to a 3/8-24-UNF
thread)
04943 Triple-fl atted Shank Adapter for 1/2” drill chucks
Recommended Method.
This method is used for drill
motors with a fi xed circular boss. With this method the
drill chuck is removed and the speed reducer is threaded
directly onto the drill chuck spindle.
You must maintain a
fi rm grip on both the drill and Speed Reducer Clamp
Handle.
1. Remove the chuck from the drill motor leaving washer
on drill motor shaft.
2. Thread the Speed Reducer onto the drill chuck spindle.
Tighten by hand. Speed Reducer has a 1/2-20-UNF
female thread.
3. Slide the clamp handle over the speed reducer and
down to the end
closest the drill
motor. Rotate
clamp handle
to the desired
position and
tighten clamp by
twisting handle.
4. Install pilot drill,
hex washer, and

MAINTENANCE
The Speed Reducer is designed to be relatively mainte-
nance-free and is thoroughly lubricated at the factory: how-
ever, periodic lubrication will increase tool life. There are four
important points of lubrication:
1. Pilot Drill
2. Planetary Gearing
3. Planet Gear Shaft
4. Input Shaft Bushing
2, 3, 4 are internal parts and require partial disassembly.
Pilot Drill Lubrication
Each time the pilot drill is removed, a thin coating of
grease should be applied between the fl ats before
being reinserted. This grease provides lubrication for
the piloting hole in the output adapter which guides
the pilot drill. After installation, wipe away all the
excess grease from around the hole to prevent
machining chips from sticking to this area.
INSTALLATION METHOD #2
This method allows the Speed Reducer to be installed in a
1/2” chuck. This also allows the Speed Reducer to be quickly
removed and the drill be used with other holemaking tools.
The disadvantage is the Speed Reducer and drill is heavier
and longer.
You must maintain a fi rm grip on both the
drill and Speed Reducer Clamp Handle.
1. Screw the Triple-fl atted Shank Adapter (04943) into
the input shaft of the speed reducer.
2. Tighten the other end of the Shank Adapter into the
chuck of the drill motor.
3. Slide the clamp handle over the speed reducer and
down to the end closest the drill motor. Rotate
clamp handle to the desired position and tighten
clamp by twisting handle.
4. Install pilot drill, hex washer, and cutter to complete
the setup.
