Pilot Bit assembled to 18" shaft.
Pilot Bit assembled to 24" shaft using the Hole Saw Arbor.
End of wire on coupon retaining bit
must extend past end of hole saw.
NOTE: The slow speed setting on
the drill motor is recommended to
prevent magnets from coming loose
and losing the coupon. Do not use
magnets on hole saws larger than
1 3/4".
Tips:
• Use a new hole saw. Time saved with the new, sharp hole saw
will be worth the small cost.
• Use low RPM with larger diameter hole saws for less wear on
the hole saws as less heat is generated
