The Spectra/Chrom® Tubing Cutter cuts most plastic tubing, leaving a flat, even edge. The special "V" shape of the tubing holder keeps the tubing perpendicular to the blade. The blade remains sharp for many cuts and can be replaced easily using only a Phillips screwdriver. Can be used on most flexible tubing 1/2" (13mm) OD or smaller. Not for use on metallic tubing.
