Bosch GSB 18V-25 & GDR 18V-215 Kit vs Bosch GSB + GBH + GWS 18V Combo Kit

Buy the GSB 18V-25 + GDR 18V-215 twin pack if you mostly drill, drive screws and want a compact impact driver with 215 Nm and two auto-drive modes. Buy the GSB + GBH + GWS kit if you need an SDS-plus rotary hammer for masonry and a small grinder for cutting and grinding. The twin pack is lighter and more focused on fastening; the three-tool kit covers more trades but gives up the impact driver and adds a hammer and grinder you may not need. Owners of the Bosch Professional 18V line rate the batteries and build highly; the trade-off is tool count against fastening performance.

• Choose the GSB + GDR twin pack if your work is drilling, screwdriving and driving long screws, and you want a light impact driver with auto-stop modes.
• Choose the GSB + GBH + GWS kit if you need SDS-plus hammer drilling into concrete and a grinder for cutting and grinding metal.
