Grøntklima 121717 is a hand deburring tool with a rotating blade for removing burrs and sharp edges from copper, aluminium and plastic pipe after cutting. The swivelling blade follows the pipe wall on both inside and outside surfaces, preparing the end for a leak-tight fitting. It is a shop-tool accessory for HVAC and refrigeration installers. Typical application is pipe-end preparation before flaring, brazing or push-fit assembly in cooling and heating installations.
