The normal position for the tool bit is illustrated below. This position is used for
.50” (12.7 mm) and smaller diameter tubing. This is the designed working position
of the tool bit and will leave virtually no burr with standard tubing. When working
with Electro-polished stainless steel tubing, slow cutting speeds must be used to
minimize the ID burr.
The tool bit may be reversed as illustrated. This reversed position may be used for
tubing with an ID greater than .50” (12.7 mm). With the extreme shear cutting action,
the burr on the ID will be virtually eliminated.
Tool Bit Installation
CAUTION:
NOTE:
Minimum burr may be obtained with a slow RPM and a slow feed, which will
cut a continuous chip.
The cutting edge of the tool bit must be located on the radial centerline.
Do NOT install the tool bit backwards.
