Keep the limits in view.

  • Do not confuse a charger manual in Downloads with the drill manual.
  • The product is marketed as compact, despite its general-purpose role in this editorial comparison.
  • Avoid treating the table weight as the total kit or battery-equipped weight.

Read the instructions for the tool and any applicable battery or charger together. Routine owner care stays outside the housing; internal service belongs with the manufacturer or an authorized service provider.

  • Bosch: decode the full model

    Consider the 300 for tight spaces and an existing 12V setup, the 400 for ordinary drilling on 18V, and the 975C when a suitable job needs hammer mode.

  • Bosch kit contents

    GSR18V-400B12 includes one BAT612 2 Ah battery and a charger; GSR12V-300N and GSB18V-975CN exclude both.

  • Bosch model and Type

    Record the model and ten-character identifier from the actual label; a sales suffix describes a package, not a verified parts match.

  • 300 versus 400

    Consider the 300 with suitable 12V equipment and smaller-shank accessories; consider the 400 for an approved larger shank or an existing compatible 18V setup.

  • GSR18V-400 controls

    Complete fitting and setup without power, then trial on matching scrap. Increase clutch only for an undamaged proud screw without abnormal resistance; stop for cam-out, overdriving or repeated shutdown.

  • 400 versus 975C

    For ordinary drilling, start with the 400’s size and complete setup; consider the 975C when a suitable hammer-drilling task justifies the extra mode and space.
