force cutting action.
This Tool Bit allows the tubing to be positioned in the Collet so that only 1/16”
(1.6 mm) to 1/8” (3.2 mm) is unsupported by the Collet at the cut line.
Another method is to use a consumable aluminum “pot chuck” which has been
made from approximately 6” (152 mm) lengths of 3/16” (4.8 mm), or 1/4” (6.4 mm)
aluminum rod or tubing.
The rod or tubing is then bored and or reamed to match the OD of the tubing to be
squared.
A very fine longitudinal slit is then cut in the consumable pot chuck, which will allow
the Collet to clamp on the product tubing.
The product tubing along with the pot chuck are loaded into the Model 301 and both
are squared.
In this manner the tube is supported and a clean burr free end is obtained.
