Capricorn PTFE tube cutter
To properly seat your Bowden tube, it is imperative to have a clean, square, end. Without this, you risk oozing, or worse, clogging, in the hot end. This super-sharp tubing cutter is the perfect tool for obtaining a clean, square cut in your tubing, every time.
Features a stainless steel blade and spring. The housing is made from tough durable plastic.
Fits up to 6mm diameter tubing. Can also be used to cut filament. (Do not use as a wire cutter or you will dull the blade, however.)
PTFE, or Polytetrafluoroethylene, is a synthetic polymer commonly used as a coating for non-stick pots and pans. It is the slipperiest substance known to man, and is said to be the only surface to which a gecko cannot stick. Although Bowden tubes can be made from several different polymers, PTFE is generally considered the best because of its high melting point and low coefficient of friction.
