Festo 218606 Tube Cutter 20 mm Cuts Polyamide

Keep these replacement pipe cutting blades from Festo as a permanent fixture in your toolbox. They come with a mounting hole to precisely fit the ZRS-series tube cutter (136-7029). Changing blades is a quick and easy job – simply unscrew the old blade, slot in the replacement and secure with the tool's holding screw. These tube cutting blades make light work of slicing cleanly through plastic or rubber pipes up to 20mm in diameter, even those with textile reinforcement.

• Blades come in a pack of ten, so you won't run out halfway through a job

• Plumbing and electrics

While you could sharpen a blade with the right tools, it isn't recommended as it's difficult to accurately bevel the edge and retain a symmetrical point. This means you could damage plastic pipework and tubing when you're cutting.
