90 25 20 Pipe Cutter For composite pipes and protective tubes
- For cutting composite pipes Ø12.0 to 25.0 mm and for cutting flexible protective tubes Ø 18.0 - 35.0 mm without damaging a potential pipe inside
- A calibration arbor can be fitted, for example for Geberit composite pipes with Ø 11.5 and 15.0 mm
- Blades: special tool steel, oil-hardened, interchangeable
- Tool body: high-grade chrome vanadium electric steel, oil-hardened
Patented blade guidance – surprisingly simple and efficient
Front cutting area for protective pipes
The patented cutting mechanism operates with two guide plates. During cutting, these vertical plates run in the troughs of the protective pipes. Only the raised part of the protective pipes, the crest, is cut. With this system of cutting, the blade always remains at a distance to the inset pipe, so that protective pipes can be cut to size after they have been installed. A rotating movement at right angles to the protective pipe is used when cutting.
Rear cutting area near the joint for composite pipes
The composite pipes are cut in the area near the joint using a pliers action. Composite pipes are plastic pipes with aluminium insert, as used in heating engineering, for example. Technically perfect ends are vital due to the need for systems to be leak tight. When inserting the composite pipe on the Knipex 90 25 20 pipe cutter, a jaw feeds the composite pipe at right angles to the blade; a clean cut edge without burrs is created. Because of the extremely sharp blade, the pipe end is not deformed during cutting. The section of pipe can be integrated directly with pipe couplings without any finishing work, e.g. in an underfloor heating circuit.
One single, convenient cutting tool is sufficient for all applications
Gone are the times when you had to work with several or even makeshift tools when installing composite pipes. The Knipex 90 25 20 pipe cutter has been set in the Knipex factory as a cutting tool for composite pipes from Ø 12 to 25 mm and protective pipes from Ø 18 to 35 mm. There is an optional calibrating mandrel, e.g. for Geberit composite pipes with Ø 11.5 and 15.0 mm. The composite pipes, which are suitable for drinking water, can then be installed diffusion-resistant after cutting. Several applications – one convenient tool.
