between the magnet core surface and the mounting plate. The two
surfaces will be kept apart by curvature, coats of paint, by surface
irregularities, bolt heads, etc. Holding power is reduced by rough or
uneven surfaces, insufficient thickness of steel or insufficient
mounting area for the magnet base. The
magnet rapidly loses its holding power when
this surface irregularity raises the air gap above
1/64"(.4mm). Keep this air gap to a minimum
and be sure to smooth the surface removing
any undue projections, chips or other items that
will not allow full metal to metal contact. If the
magnet fails to hold on a metal surface, it may
be due to this condition and a check can be
made with a feeler gauge or similar device in
order to determine if an air gap exists under the
magnet at the crucial points.
1. Place drill press on work surface so that drill
point or cutter pilot is directly over spot to be drilled. Push the red
button (A) to give power to the tool. Position the cutter directly over
the spot to be drilled and turn the magnet on by pressing the
yellow button (B). Turn power on to the motor by pressing the
green button (C). When drilling in an overhead or vertical position,
the safety strap (D) must be employed.
(Fitted in slot in base as shown)
NOTE: Replace strap if edges become frayed.
Inspect the strap before each use. New straps
are available at your retailer or D
center.
2. Gently apply pressure to feed handle until twist
drill or cutter has a full bite then apply steady
pressure until cut is complete.
3. Turn off motor and allow motor to run down

before turning magnet off.
4. Turn magnet off by pressing the yellow button. The magnet will
remain engaged for 5 seconds before releasing.
5. After each use, remove all chips from
C magnet surface.
Operation with D
Annular Cutters
1. This unit was designed
convenience and safety in mind
2. User safety:
The switches are arranged to prevent
accidental motor start up before the magnet is energized.
The handles are arranged to allow for easy vertical and overhead
placement.
3. This unit comes equipped with a quick release feed handle (E). By
depressing a button, the feed handle can be
switched from the left to the right side of the unit.
The magnet is designed to adhere to 3/8"(10mm)
or greater thickness of flat steel or iron.
NOTE: DW151 can be adapted for use with twist
drill bits with addition of DW1561 Chuck Adapter.
4. Place proper pilot pin into desired cutter from the
top and insert cutter into the arbor. Line up cutter
flats with arbor set screws. Tighten both set
screws securely. (Make sure flats are properly
located under set screws so that they remain
recessed below surface of the shaft).
5. Fill reservoir with non oil-based cutting fluid. This
fluid is formulated to give the best performance
and life to the rotary cutters. Fluid will be released down pilot shaft
by gravity feed. Test by running cutter up and down against work
surface to start fluid flowing. Do not use liquid cutting fluids while
