The Bosch RS428 is a powerful 14 A reciprocating saw offering one of the best power-to-weight ratios in its class — just 8.65 lb (≈ 3.9 kg). An innovative counterbalance system and anti-vibration handle reduce hand-arm vibration by about two-thirds, and Constant Response electronics maintain speed under load. Variable speed (0–2,900 SPM), 1-1/8″ stroke length, and a 3-position adjustable foot make it versatile for demolition, branch cutting, or overhead work.
