Bosch GSR18V-400B12 Drill/Driver Kit vs Bosch GSB + GBH + GWS 18V Combo Kit

The Bosch GSR18V-400B12 is a single compact drill/driver, and the Bosch GSB + GBH + GWS combo kit is a three-tool professional set. Buy the GSR if you want one light, simple drill for home and hobby work. Buy the combo kit if you need to drill masonry, chisel and grind, and want two batteries and a charger for a full 18V platform. The GSR is the lighter, simpler tool; the combo kit covers far more jobs but is heavier and more complex to use.

• Choose the Bosch GSR18V-400B12 if you want one compact brushless drill/driver for home repairs, furniture assembly and light drilling.
• Choose the Bosch GSB + GBH + GWS combo kit if you need hammer drilling, light chiselling and grinding, and want two 4.0 Ah batteries to share across Bosch Professional 18V tools.
