A mini tube cutter also called Hobby Pipe Cutter is a compact and versatile hand tool designed primarily for cutting small-diameter pipes and tubes. This hobby tool is widely used by professionals and hobbyists alike for tasks involving scratch-building, crafting, and DIY projects. 

This powerful Mini Tube Cutter will mainly cut plastic but it is also suitable for soft metals such as brass, copper, or aluminum tubing from >3mm (1/8") to 22mm(7/32") diameter.

The construction features a sturdy body made from aluminum alloy to ensure durability, with a sharp, rotating blade designed to score the tube's surface as the tool rotates. The cutting wheel is positioned between two guide rollers, which stabilize what you are cutting during cutting to ensure precision and consistency. The user can produce a clean and uniform groove by gradually tightening the blade and rotating the tool. Once the groove is deep enough, a slight manual twist can cleanly break the pipe.

Mini tube cutters are specifically designed for small-diameter tubes, ranging from 3 mm (1/8 inch) to 22 mm (7/8 inch), making them suitable for materials like plastic, copper, brass, and aluminum. These cutters often feature an ergonomic grip and a smooth-turning knob or screw to adjust the cutting blade.
