The verdictOur take

The GKT 18V-52 is Bosch's compact cordless plunge saw at 4.1kg, but it pairs a smaller 140mm blade with the shallowest cut in the group at 52mm (46mm on rail) and one of the loudest noise figures at 99 dB(A). It runs BITURBO brushless power on a single 18V Bosch Professional battery, and like the corded GKT its dual-groove base sits on Festool and Makita rails as well as Bosch and Mafell. We would suggest it where portability and one-battery convenience matter more than depth; if you need deeper cuts, the Makita DSP600 or Milwaukee FPS55 reach 56 to 59mm.
