Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
Ø The purpose of the BRM-60 is to drill through steel using annular cutters or standard
twist drill bits.
Ø These drills are designed to magnetically adhere to a ferrous surface using their
electromagnetic base. Generally these drills are designed and used to drill through
mild steel. This magnetic base will not work without a power connection.
o NOTE: The entire magnetic base must cover the work area to have full
magnetic adhesion. Using only a portion of the magnet is dangerous! Make
sure the base fits completely on the surface.
Ø These machines can be used vertically, horizontally or overhead (inverted) provided
strong enough magnetic adhesion and an acceptable work environment. NOTE: For
safety, the safety chain should always be used incase of an accidental power failure
or other loss of magnetic adhesion.
OPERATIONAL PRINCIPLES
Ø The main drilling shaft rotates in a left hand or right hand direction. The main drilling
motor connects to the MT3 tool holder. Either the MT3 Weldon shank or drill chuck
adapters are secured in the MT3 tool holder. A cutting bit is inserted in the adapter
which allows for contact with a surface and slowly bore a hole. Using the feed
handles on the side of the drill, the user can raise or lower the drilling motor.
MACHINE COMPONENTS
Ø The main components of the BRM-60 are the tool holder, gearbox, motor, frame and
magnetic base. The tool holder is driven by the transfer case and the motor.
o These components must be not be removed except by a qualified technician.
Power must be disconnected prior to any service.
