Summary: it is great to not have to get an extension cord to grind a chunk of old wire from around roses,or just to be able to do any other grinding job without having to have anything other than a grinder
Summary: I work on an irrigation system that covers a lot of rough ground. Everybody's go-to tool, an angle grinder cut-off doesn't work without power, unless it is cordless. Saves me from hoisting a generator into the back of a pickup and four-wheeling to the place where I need to cut something off. Has enough power, with a couple batteries, to do just about any cut-off job. Would also be handy for gas welding in the outback.
Summary: one of the few makita lithium tools that is poor. It quickly runs a battery down to the point where the battery runs hot and will not power the tool under any reasonabe load. A great uit to destroy expensive lithium batteries.
BEWARE does not ship with rapid charger DC18RA pictured and detailed on the site
24 December 2013
Summary: We received this with a black DC18RC "fast" charger, not the pictured blue DC18RA "rapid" charger. Since the pictured charger is more expensive on the amazon site, it appears we were supplied with a less expensive substitute (even though it may be newer model). Beware this is not shipped as pictured or detailed. Update 12/27/13 - we had one of the pictured chargers (DC18RA) so we tested the 2 chargers on the 2 brand new batteries we received with the order.
Summary: Bought to use on truck day to day. Been using Makita products for 33+ years. This generation of 18v Li-Ion is the greatest yet. I keep a Makita 120 Volt on the truck as well, but this one gets the most use because of convenience. It does drain batteries fast, but not unreasonably for the power it outputs. Perhaps the next generation will replace line power tools completely, but for now this comes close enough when used within reason.
Summary: This tool is amazing. It is surprising how nice it is not to have a cord getting in the way when working with a tool like this. The cut off wheel works really well and we use it all the time to slice parts. The tool does take a lot of power and runs through the batteries fairly quickly so if there is a longer grinding project we the corded version from Makita.
