The DongCheng HD114022 3–22mm Metal Pipe Cutter is a compact, precision tube cutter designed for HVAC technicians, plumbers, and refrigeration specialists. Engineered for clean, right-angled cutting of soft metal tubing, it handles copper, aluminum, and thin-walled brass pipes ranging from 3mm to 22mm in outside diameter.
Equipped with a high-grade bearing steel cutting wheel, it delivers sharp tracking and burr-free cuts without crimping or deforming thin-walled tubing. Dual smooth-rolling guide rollers ensure straight rotation around the workpiece. Its compact C-shaped cast body and knurled feed screw knob allow comfortable tightening and easy rotation inside cramped wall cavities, under sinks, and around air conditioner lines. Packaged in a slide blister pack.
