Reed's copper tubing cutters are popular due to long-lasting, quality construction. The large grip knob is easy to tighten during use, and features a built-in reamer for convenience and safety. Wide rollers yield a square cut while thin cutter wheel profile ensures a quick, clean cut. The included wheel is designed for copper, but the tubing cutter accepts a variety of other wheels to cut a variety of other materials: a great value! Reed cutting wheels are made from high shock-resistant tool steel on CNC machines and then heat treated. This process creates a thinner yet stronger blade for precision and durability. Includes the Reed lifetime warranty.
