The verdictOur take

The GST 18V-125 S is the barrel grip twin of the GST 18V-125 B, with the same 125mm wood capacity and 26mm stroke at 1.9kg bare. Its declared vibration of 7.4 m/s² cutting boards is higher than the bow handle version's 4.9 m/s² but well below Milwaukee's M18 FBJS at 15.55 m/s². Bosch's EXPERT EXST18V-155S adds 30mm of depth and a saw blade guide, at a higher price.
