Bosch, GSA 18V-28 Professional, 18 V, Cordless Reciprocating Saw

The Bosch GSA 18V-28 Professional is an 18 V cordless reciprocating saw built for demanding demolition and installation work. It runs on an 18 V Li-ion battery platform and delivers a 28 mm stroke length at up to 2,900 strokes per minute. The saw cuts wood up to 230 mm deep and handles metal profiles or pipes up to 150 mm thick. It also cuts through plastic and insulation materials on site. A brushless motor keeps material removal rates high without needing a corded power supply.

Weighing 3,200 g with an overall length of 450 mm, the saw balances cutting capacity with manageable handling for overhead and confined-space work. An ergonomic handle supports sustained use during prolonged demolition tasks. Adjustable speed settings let the operator match the stroke rate to the material being cut. Bosch supplies the tool with one S 2345 X Progressor blade for wood and one S 123 XF Progressor blade for metal. The saw is fully compatible with the Bosch Professional 18V System and the AMPShare battery alliance.
