HINTS FOR SMOOTHER OPERATION
1. Keep insides of Hougen Cutter clear of chips. Chips will
interfere with cutting to maximum depth as well as impede
free oil flow from arbor to work and can cause cutter
breakage.
2. Keep workpiece, machine, arbor and Hougen Cutter free of
chips and dirt.
3. Tighten all bolts regularly.
4. We highly recommend using a light viscosity cutting fluid
(preferably RotaMagic™ Cutting Fluid - P/N: 11742-4).
5. Occasionally check metering of cutting fluid flow. Lack of
coolant may cause Hougen Cutter to freeze in cut, slug to
stick, and may result in poor cutter life.
6. Always start cut with light feed pressure and then increase
sufficiently to achieve maximum cutting rate.
7. Ease off on pressure as cutter begins to break through at
end of cut.
8. Keep magnet and cutter free of chips and dirt.
9. if slug hangs up in cutter, turn motor off and bring cutter
down on flat surface. This will normally straighten a cocked
slug, allowing it to be ejected.
10. Cut overlapping holes as illustrated, using minimum steady
pressure. When cutter is removing material whose cross-
section is half or less than the cutter diameter, pilot should
be removed and tool should be fed with care. External
lubrication should be used.
NOTE: When cutting in this manner, cutting fluid may
escape from the cutting area. Tool should be fed with care,
using external lubrication.
11. When cutting large diameter or deep holes, it may be
necessary to stop in the middle of the cut to add cutting fluid
to the reservoir and also remove chips from around the
arbor. When doing this, do not raise the cutter out of the
hole. Doing so can allow chips to get under the teeth of the
cutter and make it difficult to restart the cut.
#1 cause of
cutter breakage and
prematurely dull
teeth is too little
feed pressure.
MAINTENANCE
In order to minimize wear on moving parts and to insure
smoother operation and longer life for your magnetic drill, the
following maintenance should be done periodically, based on
use.
1. Regularly tighten all fasteners and replace any worn
components.
2. Check motor brushes and replace if worn.
3. Check power cord and motor cord. If cracked or frayed,
return to authorized repair center for replacement.
“Babying” the Cutter through the
cut will only decrease tool life.
