A reciprocating saw, also referred to as a Sawzall, consists of a handheld tool that features a horizontal blade and a trigger on the handle. The blade moves in a push-and-pull, or reciprocating, motion and remains exposed which allows it to work in tight spaces. They use interchangeable blades to accomplish tasks ranging from demolition to remodeling. Bosch offers the 1-1/8-inch reciprocating saw which features innovative counterbalance technology and an anti-vibration handle. This helps reduce the vibration to about 1/3rd that of standard tools. It also comes equipped with a variable speed trigger to improve cutting control in various materials. Additionally, this tool features a constant response circuitry to maintain the desired speed for consistent performance under load.
