BRM- 60 MAG DRILL
10
o NOTE: Do not force the hole. Let the machine do most of the work.
Excessive physical effort should be avoided as it can cause damage to the
machine or the user.
o If the unit jams in a hole, stop the drill immediately to prevent injury.
Disconnect the drill from the power supply and loosen the cutter by turning
drill spindle counterclockwise. Never attempt to free cutter by starting motor!
Ø Make sure to keep the cutting material adequately lubricated.
Ø Ease up on feed pressure as the cutter starts breaking through the backside of the
material.
o If using annular cutters with a centering pin, the slug should eject using the
spring-loaded mechanism in the drill shank. Be mindful that this slug can
eject at a rapid rate, so be sure all is clear on the output side of this slug to
prevent injury to persons or property.
Ø Finish drilling the hole.
Ø Turn the motor off and disconnect power once the drill is safely back up in the non-
drilling position.
o Remove metal chips wrapped around cutter and tool holder. Use a leather
glove or pliers as these metal pieces can be sharp.
Ø Disconnect safety chain and move the drill to a new drilling location.
INSTALLING ANNULAR CUTTERS
Ø WARNING: Annular cutters are extremely sharp and should only be handled with a
thick glove so as not to cut the user during installation or removal.
Ø Check that the cutters are sharp and not damaged.
o Annular cutters that are dull or damaged should not be used.
Ø Insert the pilot pin into the center of the annular cutter you have chosen.
o NOTE: The pilot pin helps in locating the center of the hole as well as ejecting
the metal slug after the cut.
Ø Make certain the machine is unplugged from power.
Ø Raise the tool holder to ensure ample room to install the cutter.
o If using ¾” annular cutters, you will need to first install the ¾” MT3 Weldon
shank adapter.
Ø Insert the annular cutter into the ¾” adapter.
Ø Align the two “flat” sides of the annular cutter with the flat sides of the adapter.
o CAUTION: Make certain the hex screw is seated into the flat side and not
simply on the round side of the cutter shank.
