OFF – no rotation.
FORWARD – counterclockwise shaft rotation.
Forward is going to be the most commonly
used setting. Right-handed people will get
the most control in the forward direction.
At Foredom we define motor rotation this way:
Forward motor rotation means that the motor
is turning an accessory (bur, bit, drill, cutter,
etc.) counterclockwise when holding the
handpiece upright in your hand and you are
looking down on to the front of the accessory.
When the handpiece/accessory is applied to
the workpiece, your viewpoint changes to the
back end of the handpiece and accessory and
the forward rotation direction can be
described as clockwise.
Forward Motor Rotation
• ONLY use Chisel or Hammer handpieces or
Angle Grinder attachment for H.30

hand-
piece in Forward Rotation. Using Chisel or
Hammer handpieces or Angle Grinder
attachment in reverse can damage the hand-
piece, attachment, flexible shaft, or motor
and may cause injury.
• Use the forward motor direction ONLY for
fluted burs, drills and cutters. Most will cut
efficiently only when turning in this direction.
• Many mandrels have right-hand threaded
arbor screws which will unscrew in the
reverse direction.
• Dust and debris flies away from the user
when operated in forward in the left hand.
• Whether you are right or left handed or
REVERSE – clockwise shaft rotation.
Advantages of Reverse Rotation
• Left-handed users will have better control in
the reverse direction.
• For right handed use, dust and debris flies
away in reverse.
• Alternating motor direction helps to extend
the life of mounted abrasive points, buffs,
brushes, sanding bands, and Typhoon

burs.
• Reverse helps with accomplishing symmetri-
cal grinding and carving techniques.
• Reverse is good for “backing out” stuck
drill bits.
• Alternating motor direction makes it easier
and faster to polish metals.
• Be sure to use a mandrel with a left-hand
threaded arbor screw.
Never change motor direction while the motor is running.
