What you should know before you drill
1.
Type of material to be drilled, Brinnell or Rockwell hardness, material thickness and position should all
be determined to ensure proper selection of cutting tools.
2.
Remove any excessive mill scale or rust from surface to be drilled.
3.
When drilling thin materials, we recommends placing a steel plate under the work piece and
magnet area to increase magnetic holding force.
4.
Material that has been flame cut may become heat treated and therefore difficult to drill. Avoid drilling
near such areas whenever possible.
5.
Special cutter lubricant are available for using the machine and annular cutters in the horizontal
position. Consult your distributor for more information.
Caution: Do not drill on material where welding is also simultaneously being performed.
Drilling machine will be damaged.
Caution: Powering drilling machine from generator without proper surge protection device
between generator and drilling machine may cause damage to Printed Circuit Board in machine.
Ready to make the cut
1.
lnsert the annular cutter in to the machine arbor, lining up the flats on the cutter shank drive with
the set screws on the arbor. Secure the set screws making sure the screws are recessed in arbor
body. The surface you are working on should be clean and level, free from rust, scale, dirt and chips.
2.
Fill coolant reservoir with a water-soluble coolant
3.
Position of the Drill on the work piece.
4.
Lower cutter/drill to surface of material. When using cutter tool holder, coolant flow starts when
pilot pin is depressed. Lifting pilot pin off work surface will stop coolant flow.
5.
Place the drilling machine on the work piece, with pilot pin over the center of the hole to be cut.
6.
Move the rocker switch located on the panel to the ON position. The switch will illuminate to
indicate DC power is going to the magnet.
7. Depress motor ON switch to start drill.
8.
To start a cut, apply pressure until the cutter has established an external grove. Then apply steady
pressure through the remainder of the cut (Note: Do not peck drill when using annular cutters). The
tools are designed to evacuate chips when drilling.
After the cut
1. After the cut has finished, the slug should be expelled on the down stroke. lf the slug is not expelled
after the cut, disconnect the machine from the power source and remove the cutter from the arbor
body, then expel the slug. (Caution: The pilot should not be used to do this).
2.
After the cut is finished, return motor to the full upright position, depress motor OFF button and
wait until motor fully stops. Move magnet switch to the OFF position to release the magnetic base
from the material.
