Nibbler shears are specialized cutting tools designed for making precise cuts in sheet metal and other thin materials. They operate by using a pair of blades that move in a scissor-like motion, allowing users to cut curves and intricate shapes without distorting the material. These shears are particularly useful in metalworking and construction. These tools come in various designs, including manual and electric versions. Manual nibbler shears require physical effort to operate, while electric models provide more power and efficiency. Nibbler shears are often used in conjunction with other tools, such as metal snips and angle grinders, for comprehensive metal fabrication tasks.
