What tools come in this Metabo combo set?

It is a two-tool 18V cordless set with a drilling-focused tool plus a second 18V tool, two LiPOWER batteries, an ASC 55 charger and a MetaBOX 145 L case. Check the listing for the exact second tool, since Metabo sells several two-tool pairings.

Does it use brushless motors?

Yes. Both tools use brushless (BL) motors, which run cooler and typically give more runtime per charge than brushed motors.

Are the batteries compatible with other Metabo 18V tools?

Yes. The LiPOWER 18V packs fit Metabo's 18V cordless range, so you can share them with other bare tools on the same platform.

Is the MetaBOX case worth having?

The MetaBOX 145 L is a rigid stacking case that locks onto other MetaBOX cases, which protects the tools better than a soft bag and keeps a van or shelf organized.

Is this set good for heavy drilling?

It handles drilling and driving in wood, metal and masonry with the right bits, but it is a compact 18V kit. For sustained core drilling or concrete work, a dedicated rotary hammer is the better tool.
