This cutter can talk the talk without walking the walk. Hilmor's Large Diameter Tubing Cutter features a four-roller tracking system to keep the tube from threading. All the while, a shock-resistant steel wheel cuts through the tube like a knife through butter. It is precise and accurate thanks to its flare-cutting groove and unique, four-roller tracking system. If needed, a spare blade comes with the tool and can be stored in the handle. With its quick-action ratcheting, any technician can finish the job in a swift manner. This Tubing Cutter is an HVAC technician's best friend. It cuts so well you'll be wondering what tube cutting was like before without it!
