The glass bottle cutter is an upgraded version that can be used to cut square and round bottles. The width is adjusted to 0.8 in - 2.7 in and the length is adjusted to 2.4 in - 5.9 in. You can use this bottle cutter to easily cut any bottle you like (unless the bottle is embossed). Stainless iron material, surface coating, waterproof, wear-resistant and not easy to deform, can reduce the error of manual cutting. The three pulleys can be used to cut the bottle more easily with the rotation of the bottle, and also protect the beauty of the bottle after cutting. Our bottle cutters have 3 cutting wheels on each cutter head, and the service life is 3 times that of other bottle cutters.
