MT2 ANNULAR CUTTER ADAPTOR
This machine is equipped with a unique annular cutter adaptor system with built-in coolant directly to the
gearbox.
1. To install the annular cutter adaptor, first insert the taper end of the adaptor into the arbor of the
machine as described above.
2. Attach the coolant tank to the slide and ensure that the tube is attached properly.
3. To insert an annular cutter, first insert the pilot pin. Then slide the cutter into the adaptor, align the
proper flat with the locking screw(s) and tighten securely with the supplied hex wrench.
4. Ensure that the oil feed tap is on and coolant feeds properly by pushing
the pilot pin. If it feeds too quickly or slowly, adjust the tap accordingly.
Keep the tap closed when not in use.
GEAR SELECTION
Before drilling select desired gear range by first pushing in on spring-loaded
gear selector slider switch and then sliding selector up for high speed or
down for low speed. (It may be necessary to turn the arbor slightly in order for the gears to mesh properly).
Follow the recommended speed ranges on the cutting speed chart to set the proper speed and gear range.
CAUTION: Ensure that that gears engage fully.
CAUTION: ALWAYS ensure that the machine is fully stopped before attempting to change gears! NEVER
change gears on a running machine!

NOTE: These speeds are general recommendations only. The material should determine actual speeds
and the cutting speed recommended by the cutting tool manufacturer. See the section below
"RECOMMENDED SURFACE SPEEDS" and use the formula to calculate the best RPM.
VARIABLE MOTOR SPEED
The electronic variable motor speed control allows the motor speed to be
lowered for further flexibility for adjusting the cutting speed to suit the size
of cutter and type of material. Simply turn the thumb wheel to raise or lower
the motor speed electronically.
