§
DURABIT 1 is designed to run at the maximum available RPM from the tool this
makes the cutting procedure different in relation to the other Tube Facing Bits with
99-xxxx part numbers.
§
Make sure the tool bit clears 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 so the tool
bit clears the end, but when the tool bit is rotated, it engages the tube will a very
heavy cut.
CAUTION
CAUTION: Do not do an excess cut to reduce the risk of damage to the tool bit from an
excessive cut.
§
Use the maximum speed to turn the machine on and advance the tool bit into the
end.
§
On interrupted or out of square ends, advances the bit slowly with light feed
pressure (torque applied to the feed handle) until a continuous cut is achieved (the
tool bit is cutting all the way around the end).
§
After a full cut is achieved, use moderate feed pressure to finish the cut (either to a
just achieve a quality end or to cut to a scribe line).
