Is the battery included?

No. This is the Solo version, so it ships as a bare tool without battery or charger. You need an existing Bosch Professional 18V battery and charger.

What is the difference between the drilling, hammer and chisel modes?

Drilling mode spins only, for wood, metal and tile with the right bit. Hammer drilling adds piston impact for concrete and masonry. Chisel mode locks rotation so you can chip and break.

Can it use standard drill bits?

It has an SDS chuck, so it takes SDS-plus bits directly. For round-shank bits you need an SDS adapter chuck.

How does it compare with a corded SDS hammer?

It is more portable and needs no outlet, but a corded SDS hammer delivers more sustained power for large holes and long chiseling sessions. For anchors and medium holes the cordless unit keeps up.

Which batteries should I use with it?

Use Bosch Professional 18V batteries. For hammer drilling and chiseling, a higher-capacity pack gives longer runtime and steadier power than a compact one.
