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
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.
