A Distinctive Design Built Around Practical Use
The design patent covers the machine’s exterior appearance. In practical use, the CM5 / PTC140 is designed to remain stable on a bench or work surface while still being convenient to handle and transport between work areas.
Its compact form supports workshop, prefabrication and maintenance work where operators need a pipe cutter that can be positioned quickly without requiring a large floor-mounted setup.
Fast Lever-Feed Operation for Small-Diameter Pipe
The lever-feed version is particularly suited to frequent cutting of small-diameter pipe. Lowering the operating lever feeds the cutting wheel toward the pipe, helping the operator maintain a quick and repeatable cutting rhythm.
An adjustment mechanism allows the lever position to be fine-tuned for different pipe diameters. This reduces unnecessary repositioning and makes the operating posture more convenient when switching between jobs.
Three Cutter-Head Positions for Different Pipe Sizes
The cutter head provides three position settings for small, medium and large pipe diameters. The operator can select the appropriate position before cutting, shortening setup time and keeping the cutting wheel within a practical working range.
These operating features complement the newly patented exterior design and reflect the product’s focus on stable positioning, efficient handling and straightforward adjustment.
