The Makita DWR180Z is a cordless Ratchet Wrench powered by 18v LXT batteries.
The ratchet has  variable speed controlled by the trigger and a forward/reverse rotation.

Supplied with two socket adapters: 6.35mm (1/4") square drive and 9.5mm (3/8") square drive.
When you remove the socket adapter, the model converts to a pass through wrench which is ideal for tightening 13mm nuts.
