An Easy Cutting Method
-
Cut oversize using diagonal (wire) cutters. This is the
fastest and easiest method, but crimps the tubing end requiring steps 2 & 3
to return the ends to a clean, round, smooth appearance
-
Sand to desired length using a Dremel®
sanding disk (or equiv.) WEAR EYE PROTECTION! This
process goes rather quickly on the smaller tubing sizes. A diamond cutting disk
or small bench grinder can be used for the larger sizes. Follow up
with the Dremel sanding disk or a sharpening stone to smooth the end.
-
De-burr inside diameters as
follows:
N2018 .018" tubing use #80 drill
N2025 .025" tubing use #76 drill
N2032U .032" tubing (w/.0025" wall) use #70 drill
N2032 .032" tubing (w/.006" wall) use #76 drill
N2042 .042" tubing use #65 drill
N2050 .050" tubing use #58 drill
N2065 .065" tubing use #54 drill
N2083 .083" tubing use #47 drill
N2095 .095" tubing use #44 drill
-
De-burr outside with very fine sandpaper
or an Arkansas (polishing) stone.
Alternate Cutting Method
-
Holding the tube in a pin vise or
v-block, rotate it while scoring the outer surface with a sanding disk or
thin grinding cutter. REMEMBER, WEAR EYE PROTECTION!
-
Snap the tubing at the scored groove. The
groove must be of sufficient depth to allow the tube to break and not just
bend or kink. With a little practice, this method works well and saves a
small amount of tubing (the crimped portion that must be ground away).
-
De-burr as in steps 3 and 4 above.
