Bosch GSB12V-31 Berbequim de impacto a bateria (isolado, L)

Tips

Pair this tool with a Bosch Professional 12V 2.0Ah or larger battery for extended runtime. Use the impact mode only for masonry and concrete; switch to rotary-only for wood and metal to avoid unnecessary wear. The LED light stays on for a few seconds after releasing the trigger, helping you locate the next screw position in dim conditions.
