BRM- 35A/B MAG DRILL

RUNNING THE MACHINE
Ø Do all pre-operational and operational safety checks from Chapter 1.
Ø Consider your security and stability as well as the orientation of the machine in the
work area.
o Consider the work surface material, condition, strength, density and rigidity.
These factors directly affect the tools magnetic adhesion. Magnetic adhesion
diminishes with thinner material and rough surface. Full magnetic spec’d
adhesion is considered on 1” material. When using on material 3/8” or less,
the drill should be mechanically clamped to the work-piece.
Ø After placing the machine in work area, connect the safety chain.
o The safety chain should attach to the machine (preferably through the
carrying handle) as well as attached to the work area in such a manner that
prevents the machine from detaching or falling from the work area in the
event of magnetic deactivation or lost adhesion.
Ø Ensure the feed handles are securely attached to the feed spindle.
Ø Ensure the work surface and bottom of magnet are free of debris, oil, etc.
Ø Select appropriate size tool holder, chuck or adapters.
Ø Select and set up oiling method or cutting pastes.
o If drilling overhead or horizontal use cutting paste liberally applied to the
cutting bit.
Ø If using the machine horizontally with the oil bottle, connect bottle to the side of the
machine using the two set screws located on the drill frame.
o Connect the oil bottle tube into the side of the tool holder by firmly pressing
in the hose.
§ To remove the hose later, press in the plastic piece around the hose
towards the tool holder while simultaneously pulling the plastic hose
away from the tool holder.
o Make sure the oil bottle valve is in the off position.
§ This is generally at a 90 degree angle from the valve hose.
o Fill the oil bottle with cutting fluid.
Ø Select appropriate size annular cutter or standard twist drill bit.
o The ¾” Weldon shank uses two Allen head bolts. The annular cutters will go
in the shank and be secured on the two flat sides by the two Allen head
screws. See next section below for more specifics on using annular cutters.
o If using a standard twist drill bit you will can use the drill chuck with a ¾”
Weldon shank adapter. Secure the chuck into the Weldon shank using the
same method as standard annular cutters. Tighten the bit into the chuck.
