CAUTION:
Securing the Tool Bit
Insure that the Model 302 Tube Squaring Machine is disconnected from the
power source before installing a Tool Bit.
Insert the Tool Bit into the slot in the Cutting Head.
The cutting edge of the Tool Bit must be located on the radial centerline.
Do NOT install the Tool Bit backwards.
Position the tip of the tool bit to be just inside the inside of the tube wall. The tip
must always be Inside of the tube bore to achieve a flat end. The tip location is
critical on .50" to 1.00" tube because when tip is too close to the center of the tube
the chip may roll into the tube and scratch the ID.
Tighten the cap screws to secure the tool bit(s) to the cutting head.
CUTTING PROCEDURES
DURABIT 1 Tool Bit
The DURABIT 1 is designed to run at the maximum available RPM from the
tool which makes the cutting procedure different relative to the other Tube
Facing Bits with 99-xxxx part numbers.
Visually verify that the tool bit will clear the end of the tube with the feed fully
retracted (normal return position). A tube end that is cut at an angle (not
square) can be set such that the tool bit clears the end, but when the tool bit
is rotated it will engage the tube will a very heavy cut.
