Tube cutter K2 n-ob22 for copper pipes 3–22 mm, rolling/rotary cutting

K2 n-ob22 is a rolling tube cutter designed for cutting copper pipes with diameters from 3 to 22 mm. The compact, handheld tool uses a rotating roller and a cutting wheel mechanism to deliver straight, burr-free cuts suitable for plumbing, HVAC and refrigeration applications. Its small profile and simple rotary action make it convenient for on-site pipe preparation and for working in confined spaces where a clean, accurate cut is required.

Advantages

The rolling/rotary cutting system provides consistent, square cuts with minimal deformation of the copper tube. The cutter’s compact design allows access to tight spots and makes it easy to carry between job sites. The mechanism reduces the need for post-cut deburring and speeds up repeated pipe-fitting tasks. Durable construction ensures stable alignment of rollers and cutting wheel for reliable, repeatable results.

Suitable for

• Cutting soft copper pipes and tubing with diameters from 3 mm up to 22 mm
• Plumbing repair and installation work in residential and commercial settings
• HVAC and refrigeration piping preparation
• On-site and tight-space pipe cutting where portability is required

Key specifications

• Material compatibility: soft copper tubing
• Cutting diameter range: 3–22 mm
• Cutting mechanism: rotating roller with cutting wheel
• Design: compact, handheld rolling tube cutter
• Cut quality: straight, low-burr cuts suitable for soldering or fitting

How to use

Position the tube cutter around the copper pipe at the desired cut point and tighten the tool until the cutting wheel contacts the tube surface. Rotate the cutter around the pipe, gradually tightening the tool after several rotations to maintain cutting pressure. Continue rotating until the pipe is separated. After cutting, inspect the edge and remove any remaining burrs if necessary using a deburring tool or small file to prepare the pipe for joining or soldering.

Usage recommendations

Use the cutter on clean, unsupported pipe sections and avoid excessive tightening to prevent tube deformation. For best results, secure the pipe to prevent rotation during cutting and check the cutting wheel periodically for wear; replace the wheel if cuts become uneven or require excessive force.
