Compact and lightweight design: the small reamer weighs 0.17 kg, with a 2 inch diameter and 2.36 inch height, taking up little space in your toolbox. Wide pipe compatibility: suitable for copper, aluminum, PVC, and PPR pipes with an outer diameter of 1/4 inch to 15/8 inch. Efficient chamfering and deburring: four cutting edges deliver a smoother chamfer, and burrs can be easily removed from either the inner or outer edge of the pipe. Durable and ergonomic: made from aluminum alloy, providing strength and resistance to deformation, with a nonslip shell for easier operation. Practical use scenarios: Prepare ends of copper, aluminum, PVC, or PPR pipes for fittings during home plumbing repairs. Deburr and chamfer pipe ends during installation of irrigation systems or water supply lines. Rework small sections of pipes in DIY projects or light construction where precise edge finishing is required.
