What it does: Chain pipe cutter designed to cut vent tailpipes and vent pipes with diameters from 3/4 in to 3 1/4 in. The tool delivers consistent, controlled cuts in tight spaces where a standard tubing cutter or saw would be difficult to use. Key components and performance: The adjustable chain carries 15 rollers, each fitted with a cutting wheel blade. The chain's alloy steel construction allows full engagement of all 15 cutting wheels for even cutting pressure and reliable performance across the specified pipe sizes. Materials and durability: Chain and rollers are made from alloy steel for strength and wear resistance. Cutting wheel blades are mounted on each roller to distribute cutting load and extend service life. Ergonomics and handling: Padded ergonomic handle provides a comfortable, slipresistant grip for safe operation. The tool's compact, understated design supports both onboard (inside vehicle or equipment) and offboard use. Where it works : Designed for use in narrow and confined spaces where access is limited. The adjustable chain conforms around pipes for secure cutting and better leverage whether working inside a vehicle or from outside. Use scenarios 1) Trimming an exhaust vent tailpipe inside a vehicle chassis: wrap the chain around the pipe, engage all 15 cutting wheels, and rotate for a clean, controlled cut without needing large clearances. 2) Cutting vent pipe runs in tight HVAC or appliance compartments: the compact chain design allows access where a standard cutter cannot reach. 3) Onvehicle and replacement: convenient for mobile technicians who must work both inside engine bays and underneath vehicles for consistent cuts. Why customers choose this tool Fits common vent pipe sizes (3/4 in – 3 1/4 in) so one tool covers multiple jobs. Multiple cutting wheels on an adjustable alloy steel chain provide even cutting pressure and reduce the need for repeated adjustments. Padded ergonomic handle and compact form factor make it safer and easier to use in confined locations.
